    Modelación física del flujo a través de las compuertas radiales de la derivadora Cañar
    (Universidad de Cuenca, 2014) Tinoco, Vicente; Cisneros, Felipe; Pacheco, Esteban; Carrillo, Verónica; Calle, Edison; Domínguez, Juan; Garate, Johana; Solís, Katty; Universidad de Cuenca; Dirección de Investigación de la Universidad de Cuenca; DIUC
    The Cañar River lower basin is a coastal flat area with a high hydro-economic potential, however this zone is vulnerable to flooding. The Ecuadorian Government invests in a flood control project. The project design alternatives need testing in a physical model for supporting the final design. The variables related to the flow through the radial gates of the diversion works are investigated in a physical model. A discharge curve was calibrated for the gate operation. In addition, the best gate location was determined, as well as the optimum still basin depth. Unusual osculation with negative flow directions were found for specific tests. This phenomenon has a scour effect. In order to solve this problem, changes in the geometry of the still basin entrance are recommended by adjusting it to the flow profile.

    Modelamiento de operación de embalses para el proyecto integral de riego en la cuenca del río Macul
    (Universidad de Cuenca, 2014) Tinoco, Vicente; Willems, Patrick; Wyseure, Guido; Cisneros, Felipe; Universidad de Cuenca; Dirección de Investigación de la Universidad de Cuenca; DIUC
    An irrigation project is planned in the Macul Basin Ecuador for developing the agriculture as the main income in the region. The proposed water system comprises three large reservoirs damming the rivers Macul and Maculillo. The river basin planning and operation was investigated by modelling alternative reservoir operation strategies aiming at a sustainable balance between irrigation and river ecology by integrated reservoir/river management. The model simulates the integrated water system for long term periods of data, covering also several historical extreme events. Results indicate that the planned irrigation volumes are higher than the available water for a sustainable irrigation. Two lines of action are suggested for reaching the target irrigation demands: one is to design a deficit irrigation schedule, and the second implies modification in the reservoir’s spillway height.
