Caracterización del comportamiento hidráulico de un tramo del río Calabí en el sector de Toma utilizando un modelo matemático

Abstract

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.
