(2013) Espinoza Márquez, Patricio Armando; Vintimilla Rojas, Gustavo Enrique; Cisneros Espinoza, Felipe Eduardo
The Project “Plan for the Efficient Use and Water Control in the Province of Los Ríos” (PACALORI) strives for the regularization for the water potential of this province, by implementing hydraulic structures to facilitate the use and distribution of water. Within these structures, a Calabí river bypass through direct intake is expected, located in the right hand margin. For the optimal design of said structures, a hydraulic behavior characterization of the River Calabí in the in the intake sector, has been established in the in the present study, using a mathematical model. Mathematical modeling has been performed with the software HEC-RAS and its extension HEC-GeoRAS developed to process georeferenced data. In developing the geometry of the Calabí river, 12 cross sections raised along the section being studied were used, for additional cross sections, a digital elevation model with base cartography at a scale of 1:10000 were used. In this thesis, a calibrated mathematical model of a section of the Calabí river comprised of the intake sector has been obtained, in which the discharge curve in the intake sector and floodplains for flow rates for return periods of 50 and 100 years was determined. These values were 426.78 and 458.73 hectares respectively.
Evaluación hidrológica e hidráulica del Río Tomebamba tramo Balzay-Monay mediante modelación matemática del flujo en uni y bidimensional

Mathematical modeling of water flow in rivers is a tool that helps us assess the capacity of a river for high flows and thus identify sites vulnerable to flooding. The study area includes the Tomebamba River; It is located in the city of Cuenca belonging to the province of Azuay. Three mathematical models were used: HEC HMS, HEC RAS and Iber and in conjunction with the GIS geographic information system, flood zones were defined for different return periods. The HEC HMS model was used to model the contributing basin and determine the output hydrograms for the return periods of 5, 10, 25, 50 and 100 years, with peak flows ranging from 99.7 m^3/sg to 289.4 m^3/sg respectively for the smallest and largest return period. To make the hydraulic model in HEC RAS, previously with the Hec GeoRAS complement, the cross sections were defined, as well as 8 bridges existing in that section. In the Iber model, a 1 meter pixel DEM was used and the bridges were also entered as internal conditions in the program. Finally, the flood and velocity maps were created for the return periods analyzed and with the help of ArcGIS the flood areas were quantified.
