    CALIDAD DEL AGUA EN EL SECTOR RURAL DE CUENCA, CASO DE LOS SISTEMAS COMUNITARIOS “TIERRAS BLANCAS” Y ‘CONCHAN DEL MILAGRO’ DE LA PARROQUIA DE EL VALLE
    (Universidad de Cuenca, 2025-09-23) Sanizaca Calle, Aldo Xavier; Sigcha López, Fausto Nicolas; Idrovo Murillo, Diego Benjamín
    In the canton of Cuenca, some rural communities have their own autonomy, which allows them to adequately manage their resources and generate a response to the needs of their population. One of these needs is the supply of drinking water to their beneficiaries. The drinking water supply systems that serve the communities “Conchan de Milagros” and “Tierras Blancas”, belonging to the parish “El Valle”, require maintenance and redesign interventions to improve treatment efficiency. The present work includes an evaluation of the quality of the water supplied in the communities, by taking samples for analysis, inspection of the elements that make up the system through field visits and the redesign of the drinking water treatment plant. The existing infrastructure has been considered. In the case of small communities, a socialization was carried out with each of the beneficiaries in order to gather suggestions, opinions and common problems, seeking solutions to them. Once all the information was collected, a redesign of a slow filter for the community of “Conchan de Milagros” and the design of a slow filter for the community of “Tierras Blancas” were proposed, together with the construction budget.

    ANÁLISIS DE AGUAS NO CONTABILIZADAS EN EL SISTEMA DE AGUA POTABLE DEL BARRIO TRES DE MAYO MEDIANTE MACROMEDICIÓN POR ULTRASONIDO
    (Universidad de Cuenca, 2025-09-26) España Medina, Daniel Andrés; Carrillo Serrano, Verónica Margarita
    In Ecuador, one of the most common problems among drinking water systems is non-revenue water, which represents the loss of water resources during the distribution and supply processes. This phenomenon generates significant economic and environmental impacts, such that water losses are estimated to be between 50% - 60% in our country. Given the seriousness of this problem, the aim is to quantify the unaccounted-for water in an urban area of the city of Cuenca known as Barrio Tres de Mayo (Rio Amarillo). For this purpose, Ultrasonic bulk water metering will be used, using the water entering the system, the registered consumption of users with meters and the estimated consumption of users without drinking water meters.

    Evaluación Hidráulica Sanitaria de la Planta de Tratamiento de Agua Potable de la Comunidad de Guachún-Paute
    (Universidad de Cuenca. Facultad de Ingeniería, 2025-10-17) Chicaiza Quilli, Erika Fernanda; Garay Villavicencio, Karen Tatiana; Vázquez Guillen, Gabriela Belén; Pacheco Tobar, Esteban Alonso
    This study evaluated the hydraulic and sanitary efficiency of the drinking water treatment plant (DWTP) in the community of Guachún, located in the Paute canton, Ecuador. The research addressed the need to ensure the quality of water intended for human consumption, within the framework of optimizing water resources and protecting public health. A technical methodology was applied, which included the physical, chemical, and microbiological characterization of water under various climatic conditions, along with a hydraulic analysis of the units comprising the conventional treatment system. Parameters such as retention times, velocity gradients, and flow rates were analyzed through practical tests, operational records, flow measurements, jar tests, and tracer studies. The results showed a significant improvement in the quality of treated water, particularly in the reduction of color and turbidity, with many parameters meeting current regulatory standards. However, the study also identified the need for maintenance and optimization of certain infrastructure components. In conclusion, it was determined that the Guachún DWTP requires more efficient management, involving both preventive and corrective actions to strengthen the system and ensure better quality drinking water for the population.

    Evaluación de patologías, propuestas de rehabilitación estructural y plan de mantenimiento: Aplicación a una vivienda multifamiliar en la ciudad de Cuenca
    (Universidad de Cuenca, 2025-09-24) Tello Benavidez, Patricio Alexander; Mogrovejo Carrasco, Daniel Estuardo
    Reinforced concrete and confined masonry structures are designed to meet functional and structural requirements throughout their service life; however, pathologies originating from construction or design deficiencies can arise, which affect their performance and increase maintenance costs over time. This situation was evident in the building under study, which, after 25 years of service, presented several pathological problems, particularly due to a floor plan configuration that increased seismic vulnerability and the continuous exposure of the posterior area to weathering. Semi-destructive and non-destructive tests were conducted to evaluate the property, analyzing its structural behavior under permanent, variable, and accidental loads, with the support of ETABS structural analysis software. In addition, compliance with the minimum requirements established by current regulations was verified. Based on these results, a series of interventions were proposed to rehabilitate the building and ensure the safety and functionality of its occupants. Finally, a periodic maintenance plan was recommended, and a reference budget was presented for the selected rehabilitation solution.

    Análisis comparativo de transitorios en una chimenea de equilibrio con orificio y una chimenea de equilibrio de sección compuesta
    (Universidad de Cuenca, 2025-09-24) Villavicencio Fernández, Manuel Alejandro; Reyes Zuña, Doménica Giselle; Pacheco Tobar, Esteban Alonso
    This study presents a comparative analysis of the hydraulic behavior of two surge tank configurations—a surge tank with an orifice and a composite-section surge tank—under transient flow conditions caused by sudden valve closures and openings. A numerical-iterative procedure based on the rigid water column model is employed to simulate flow dynamics and piezometric level oscillations within the surge tanks. Both configurations are evaluated through critical scenarios adapted to specific hydraulic conditions, derived from a case study located in Ecuador. The methodology includes the definition of hydraulic and geometric parameters for each surge tank type, accounting for variations in the orifice diameter and the upper widening of the composite section. Key variables associated with transient phenomena, such as water level oscillations, stabilization times, and amplitude of fluctuations during the events, are analyzed. This work aims to provide clear technical criteria for selecting the appropriate surge tank configuration based on the operational characteristics of the hydraulic system and flow conditions, thereby contributing to the efficient and safe design of pressurized conduits in regions with high topographical complexity.

    ANÁLISIS DE LA CALIDAD DEL AGUA EN EL SECTOR RURAL DE CUENCA, CASO DE LOS SISTEMAS COMUNITARIOS “CARMEN DEL CONCHÁN” Y “ CONCHAN DEL CISNE” DE LA PARROQUIA DE EL VALLE
    (Universidad de Cuenca, 2025-09-25) Carchi Fernández, Wendy Cristina; Peñaloza Ganán, David Herman; Pacheco Tobar, Esteban Alonso
    This paper analyzes the water quality and technical condition of the community water supply systems “Carmen del Conchan” and “Cisne del Conchan”, located in the parish of El Valle, canton Cuenca, province of Azuay. Currently, the evaluation of community systems is based on the level of coverage and quantity of water supplied, which generates systems with technical deficiencies, leaving fundamental aspects such as quality in the background. In addition, the urban-rural gap generates neglect in terms of updating and validating information, which delays development processes in rural areas. This paper analyzes the current status of community systems in terms of water quality, i.e., the analysis and evaluation of treatment and disinfection systems, but also of distribution and catchment systems. With this, technical solutions adapted to the conditions of each community are proposed, and with them, the efficiency of filtration systems as a treatment process is evidenced, as well as the importance of making known the need for a disinfection system to improve the conditions of drinking water. Finally, it is identified that the values of endowment established by the current standard in the country tend to be high compared to the results obtained in this study, which leads to the oversizing of the technical solutions in civil works. This situation implies an increase in investment costs for the beneficiary communities. Therefore, it is considered essential to update the information at the rural level for the development of more efficient and sustainable designs in future research and projects.

    Diseño del sistema de alcantarillado sanitario para la comunidad de Sigsihuayco, de la parroquia Honorato Vásquez del cantón Cañar
    (Universidad de Cuenca, 2025-09-24) Vintimilla Calle, Abraham; Carrillo Serrano, Verónica Margarita
    This work, "Sanitary Sewer Design for the Community of Sigsihuayco, Honorato Vázquez Parish, Cañar Canton," proposes an alternative design for a sanitary sewer system for the community. In this context, it is presented that the community does not offer this basic service, which represents a serious lack of attention from the authorities towards the population due to existing health problems for the residents and the well-being of the area. Therefore, an alternative solution is proposed for this problem. This work includes a preliminary study of the area, a characterization of the community and its current situation, which was compiled from the various sources of information used, to provide an alternative sanitary sewer design with its different units and sections. A budget for this alternative was also developed based on current trends. For the design, the knowledge acquired during the program was used, along with the recommendations of the various strict national standards. The budget study recommends using PVC as the primary materials for the proposed collector pipes and residential connections, and concrete as the inspection wells. This provides a solid proposal with a detailed description of the community, unit design, construction budget, and system plans.

    Factibilidad técnica para los usos del agua de lavado de las unidades de la planta de potabilizadora de Tixán - Fase 1
    (Universidad de Cuenca, 2025-09-23) Cumbe Hurtado, Diego Fernando; Alvarado Martínez, Andrés Omar
    This research will evaluate in a first phase the technical feasibility of reusing wash water from the Tixán Drinkable Water Treatment Plant (DWTP) in Cuenca, Ecuador, as an option to optimize the use of water resources in the face of growing climate challenges and prolonged periods of drought. This study will focus on the characterization of the clarified effluents from the washing of decanters and filters. Laboratory analyses were carried out on different dates to determine key parameters, considering the DWTP characteristics and comparing them with the limits established in Ecuadorian regulations. The results indicate that most parameters are within the permissible limits and that the plant has the adequate processes for their treatment; the lead concentrations could suggest the need for a prior treatment. Several options for the treatment of the wash water at the plant were studied, proposing a feasible solution for its reconditioning. The recoverable water volume could cover a considerable population demand, demonstrating the high potential of this practice in the optimization of water resources.

    Análisis de transitorios para el diseño o evaluación de una columna piezométrica
    (Universidad de Cuenca, 2025-09-24) Torres Delgado, Emily Maritza; Pacheco Tobar, Esteban Alonso
    In mountainous areas, hydraulic structures such as galleries, low-head tunnels, and pressure pipelines face significant risks associated with hydraulic transients caused by sudden changes in flow regimes at control points (valves, pumping equipment, and turbines). These changes result in abrupt pressure variations, leading to phenomena such as water hammer and undesirable oscillations. The effects include damage to joints, reverse leaks, structural collapses in tunnels, and fluctuations in reservoir levels. To mitigate these impacts, the design and use of piezometric columns and surge tanks are required. The theoretical framework offers various methodologies and models, both empirical and theoretical, to analyze these phenomena. However, an integration of methodologies and procedures that enable a standardized approach to design and evaluation for projects has not yet been developed. This creates uncertainty in review, evaluation, and alternative selection procedures, impacting the implementation and cost of the works. In this context, based on a review of theoretical aspects and fundamental technical criteria, an evaluation of design procedures and best practices for sizing piezometric columns and surge tanks has been proposed. Through the application of a case study, the aim is to contribute to the development of a methodology that standardizes aspects related to review and evaluation.

    Análisis exploratorio de modelos guiados en datos informados por la física como modelos subrogantes en problemas de mecánica de sólidos no lineales
    (Universidad de Cuenca, 2025-09-25) Aguilar Valarezo, Emerson Roberto; Merchán Avila, Daniel Esteban; Samaniego Alvarado, Esteban Patricio
    This work presents a proof of concept based on a multiscale data-driven (DD) approach to modeling the elastoplastic behavior of materials without using explicit constitutive laws. Two configurations are studied: a one-dimensional case (bar) and a two-dimensional case (plane strain), considering both hardening and softening plasticity. At the one-dimensional and twodimensional microscopic scales (with hardening), synthetic data were generated for the material under tensile loading and for the unit cell subjected to shear loading, respectively. These stress-strain data were fed into a DD model which, at the macroscopic scale, solved the problem without resorting to a constitutive model. Adequate convergence was achieved in both hardening cases (one-dimensional and two-dimensional). However, in the onedimensional softening case, increasing the number of elements (from 3 to 5) caused the softening model to fail to achieve convergence. In the two-dimensional softening case, a Deep Ritz-type variational model was used to perform virtual shear experiments on the unit cell. These experiments used Dirichlet-type boundary conditions and the equilibrium equations of continuum mechanics to obtain data on material behavior. The 2D softening results showed that the DD model presents difficulties in solving the problem, highlighting the need for methodological adjustments in scenarios with strain localization. MATLAB and Python were used alongside deep learning libraries for model training. The study demonstrates the potential of the DD approach to model complex materials without requiring an explicit constitutive formulation.

    Evaluación sísmica del edificio patrimonial del antiguo Colegio Borja: análisis modal y pushover con el método del macroelemento discreto
    (Universidad de Cuenca, 2025-09-25) Ordóñez Chacha, Miguel Ángel; Urgilés Verdugo, Carlos Santiago; Jiménez Pacheco, Juan Carlos; García Erazo, Hernán Alfredo
    This study assesses the seismic behavior of the Antiguo Colegio Borja (ACB) heritage building, located in the Historic Center of Cuenca, Ecuador. The structure, constructed ofunreinforced brick masonry, exhibits an irregular plan geometry due to a curved appendage attached to the main block, leading to structural uncertainties associated with eccentricities, torsion, and variable stiffness. To address these complexities, the discrete macro-element method was employed using the 3DMacro software. Based on this model, two key analyses were performed: a modal analysis to characterize the building's dynamic response and a nonlinear static pushover analysis to determine its capacity curve and fragility. The modal analysis results indicated that the dominant modes are translational, with significant participation from the flexible diaphragms and the curved appendage, while the pushover analysis revealed brittle behavior and a reduction in the overall structural capacity. Furthermore, a parametric study demonstrated that shear strength (τ0) has a critical impact on the global resistance, and the building's lateral capacity was found to be anisotropic. The study concludes that the curved appendage induces detrimental torsional effects and reduces the structure's load-bearing capacity, highlighting the importance of evaluating the building as an integral system. This work provides a significant contribution to the structural conservation of built heritage in seismic zones and lays the groundwork for future interventions on historic buildings with irregular geometries.

    Estimación de la demanda de taxis del aeropuerto Mariscal Lamar de la ciudad de Cuenca
    (Universidad de Cuenca, 2025-09-23) Buri Guamán, Edwin Humberto; Correa Barahona, Diego Estuardo
    The availability of taxi services at the Mariscal Lamar Airport in Cuenca presents significant challenges, particularly during peak hours, resulting in long passenger wait times and inefficient service distribution. To address this issue, the objective of this study was to estimate taxi demand using predictive models that allow for anticipating operational conditions and improving transportation planning in the airport area. The methodology involved primary data collection through manual counts conducted on-site for one week, complemented by variables such as number of flights, weather conditions, and hourly characteristics. To strengthen the analysis, a Monte Carlo simulation was applied to expand the database and capture the inherent variability in demand behavior. Subsequently, three models were trained and compared: multiple linear regression, Poisson regression, and a Random Forest model, with the latter demonstrating the best performance (RMSE = 7.91, R² = 0.899). The results show that variables such as the number of passengers per airline, the average number of passengers per taxi, and the time of day have the greatest influence on demand. In conclusion, the use of predictive models combined with simulation techniques allows for accurate estimation of taxi demand at the airport, contributing to more efficient ground transportation management.

    Análisis modal y de capacidad sísmica del edificio patrimonial del antiguo colegio Borja ante fallas fuera del plano
    (Universidad de Cuenca, 2025-09-24) Mejía Cornejo, Álvaro Leonardo; Pineda Uyaguari, Martín Alejandro; Jiménez Pacheco, Juan Carlos
    This study deals with the seismic evaluation of the heritage building Antiguo Colegio Borja (ACB), a large unreinforced masonry structure located in the city of Cuenca, Ecuador. The analysis is carried out with special attention to the behavior of the building under out-of-plane failure mechanisms. The investigation starts with an exhaustive characterization that includes detailed geometric surveys, determination of mechanical properties by means of standardized tests, and analysis of previous damage. For numerical modeling, 3DMacro software was used, implementing the discrete macroelement analysis methodology, which allows to adequately represent the nonlinear response of the masonry. The modal analysis identified the predominant vibration modes, while the seismic capacity analysis quantified the vulnerability of the building to lateral forces in terms of maximum achievable strength and ultimate deformation capacity before collapse. The findings of the present study reveal critical damage patterns associated with the interaction between structural elements and highlight the importance of connections in the overall response. The methodology developed provides a framework for the evaluation of similar heritage structures, offering technical bases for intervention decisions that balance conservation and seismic safety.

    Estudio de mejoramiento de suelos expansivos con la adición de fibras de polipropileno
    (Universidad de Cuenca, 2025-09-24) López Reinoso, Josué Sebastián; Pacurucu Álvarez, Andrea Carolina; Santacruz Reyes, Karla Johanna
    The purpose of this study is to evaluate the behavior of a clayey soil through the addition of polypropylene fibers at different dosages. For this purpose, laboratory tests were conducted, including Atterberg limits, standard Proctor compaction, free swell, and controlled swell tests. Polypropylene fibers were incorporated in dosages of 0.5%, 0.6%, 0.7%, 0.8%, 0.9% and 1% by weight, based on the standard Proctor test. The results show that, as the fiber content is increased up to a dosage of 0.7%, a reduction in the percentage of free swell and controlled swell of the soil is observed, demonstrating the effectiveness of polypropylene fibers in the improvement of expansive soils. This behavior is due to the fibers' ability to act as a three-dimensional reinforcement, which restricts the soil’s expansion and contraction movements.

    Estudio vial de prefactibilidad para el mejoramiento de la vía 10 de Agosto en la Parroquia Delegsol del Cantón Chordeleg
    (Universidad de Cuenca, 2025-09-24) Albarracín Pintado, Tomas Alejandro; Tigre Matute, Kevin José; Mogrovejo Carrasco, Daniel Estuardo
    The 10 de Agosto road, with a length of 1.8 km, serves as a key transportation corridor for the Delegsol parish, Chordeleg canton, as it connects residential areas with productive and touristic sectors of the region. Its frequent use by light vehicles has led to increasing demand on an infrastructure that currently presents both geometric and structural limitations. In light of this situation, the need arises for a redesign proposal aimed at improving circulation conditions, reducing travel times, enhancing road safety, and efficiently utilizing available resources. Within this context, and following the topographic survey, traffic analysis, and geotechnical assessment of the terrain, the need for a comprehensive geometric design of the 10 de Agosto road was identified, with specific adjustments in critical segments that present physical or functional constraints. As a response, solutions such as lane widening (shoulders), adjustments to curve radii, and the implementation of porous pavement in sections where conventional drainage was unfeasible were applied, all aimed at improving road performance, ensuring safer conditions, and maintaining adequate infrastructure functionality. These interventions were defined in accordance with the guidelines and standards established by the Ecuadorian Ministry of Transport and Public Works. Finally, a referential budget was prepared using unit prices provided by the Chordeleg municipal GAD, supporting the technical and economic feasibility of the proposal. This study offers a concrete contribution to the improvement of rural road infrastructure.

    Diseño integral de un sistema de drenaje para vías de pavimento y lastre en la parroquia de Santa Ana
    (Universidad de Cuenca, 2025-09-24) Chuquimarca Peralta, Edwin Andrés; Jiménez Moscoso, Wilson Eduardo; Sánchez Cordero, Esteban Remigio; Morales Matute, Oscar Patricio
    Efficient drainage design refers to its importance in protecting the road infrastructure that connects populations, preventing waterlogging, landslides and road deterioration. This guarantees safe and continuous trafficability, essential for community development and communication. This thesis focuses on the design and evaluation of the drainage system for the road that connects the communities of San Pedro, Bella Unión, Santa Bárbara and Sigsicocha in the parish of Santa Ana. The methodology used in this document combines the application of fundamental principles of hydraulics and hydrology for the design calculations, since sufficient parameters and calculations are used for the design of ditches, culverts and subdrains. This information is complemented with numerical modeling in IBER and Hec-Ras for the verification of culvert and ditch sizing, respectively. This project focuses on revealing whether the current dimensions of the ditches in the paved section are sufficient for the estimated flows. It also proposes adequate dimensions for the ditches in the ballasted road and analyzes the need to resize and add culverts in this segment to ensure hydraulic capacity. In addition, the implementation of subdrains is recommended for efficient management of surface flows. These findings highlight the importance of proper drainage design and contribute to improving the functionality of the existing drainage system.

    Evaluación sísmica del edificio patrimonial del antiguo Colegio Borja utilizando macro modelización dentro del esquema pórtico equivalente
    (Universidad de Cuenca, 2025-09-23) Amaya García, Nathaly Cristina; Vélez Barreto, Kevin David; Cárdenas Haro, Xavier Ricardo; García Erazo, Hernán Alfredo
    The thesis addresses the seismic response of the Antiguo Colegio Borja (ACB), a heritage building made of unreinforced masonry in Cuenca, Ecuador. Built with bricks and lime mortar, it has flexible floors and walls with openings that affect its rigidity. It was modeled using macromodeling with 3Muri software, using the Equivalent Frame Approach (FME/FEA) that allows its analysis through its geometric and mechanical properties. A detailed survey was carried out that included wall thicknesses, opening dimensions, and floor characteristics to evaluate its behavior as rigid diaphragms. According to the results, the modal analysis identified 66 vibration modes, with a mass participation factor greater than 90% in both directions, complying with regulations. The first mode, with a period of 0.32 s, indicates a relatively rigid structure. Pushover analyses with uniform and triangular loads showed non-linear behavior, with sequential failure mechanisms and redistribution of forces. Fractures due to bending, compression, and shearing were detected in specific elements, in addition to the ineffectiveness of certain structural components. To improve seismic response, three strategies are proposed: increasing wall continuity by reducing spans to improve stiffness and strength; dividing the building into independent blocks using structural joints to mitigate irregularities in the floor plan; and stiffening floors and roofs with a reinforced concrete slab that ensures adequate rigid diaphragm behavior, preventing out-of-plane failures. These measures seek to preserve the historical value of the ACB and ensure its safety in the event of seismic events.

    Estudio comparativo de los métodos de Martson y ATV para cálculo mecánico de tubos flexibles enterrados
    (Universidad de Cuenca, 2025-09-23) Chimbo Vélez, Edgar Fernando; Guamán Coronel, Marcos Omar; Pacheco Tobar, Esteban Alonso
    Diametral deformation in pipelines largely depends on whether the material is rigid or flexible. The Marston model, originally developed to simplify the mechanical load analysis for rigid pipes based on the Marston Spangler theory, allows its extension to flexible pipes through a modified equation. Alternatively, the ATV-DVWK-A 127 theory compiled in the UNE 53331 standard has been specifically developed for the mechanical analysis of flexible pipelines, accounting for both soil and live loads, as well as short- and long-term deformations occurring during installation. This study presents a comparative analysis of both theoretical approaches, along with the main regulatory considerations, through a case study involving the mechanical analysis of buried flexible pipelines under typical installation conditions. The comparison includes simulations carried out using the AseTUB software package, which follows the guidelines of the UNE 53331 standard. Results indicate that the Marston model is significantly more conservative than the normative approach, potentially leading to an overestimation of the loads acting on the pipe. In contrast, the ATV-DVWK-A 127 theory, as incorporated in the UNE 53331 standard, provides more realistic estimates for flexible pipes, as long as the input values are thoroughly applied in the equations defined by the standard. The present analysis aims to contribute to the improvement of calculation procedures and the practical applicability of the Marston-Spangler and ATV-DVWK-A 127 approaches.
