Construcción de las Curvas de Caudales Clasificados en la CHE Trasvase Sabanalamar – Pozo Azul

Abstract

El siguiente trabajo plantea como principal problemática el desconocimiento de las interrelaciones de los caudales trasvasados en diferentes periodos de tiempo en las estructuras hidráulicas de Sabanalamar y Pozo Azul pertenecientes al Valle Caujerí. Tiene como objetivo general construir una serie de curvas que vinculen los posibles caudales trasvasados en destiempo teniendo en cuenta el año hidrológico y que esto posibilite la correcta interpretación de los parámetros económicos ideales para el correcto funcionamiento de una pequeña central hidroenergética. Para materializar el anterior objetivo tuvimos en cuenta las principales particularidades del escurrimiento y las estrategias para su aprovechamiento, después seleccionamos los parámetros hidrológicos en el cierre de interés. Luego proseguimos a la selección de una cuenca análoga con una estación hidrométrica poseedora de datos superiores a los diez años, analizamos y procesamos las observaciones medias diarias registradas del escurrimiento de dicha estación. Finalmente construimos las curvas de caudales clasificados de dicha cuenca análoga y determinamos los diferentes coeficientes modulares partiendo de las observaciones realizadas. Dicho algoritmo fue tomado como referencia para la confección de las curvas de caudales clasificados del Trasvase Sabanalamar y la Presa Pozo Azul, el cual nos permitió concluir que todo el caudal determinado en la mencionada cuenca, aún el alterado, no debe ser derivado. También obtuvimos una detallada información de los diferentes posibles momentos por los que puedan transitar los caudales en el cierre seleccionado.

The following work raises as the main problem the ignorance of the interrelationships of the flows transferred in different periods of time in the hydraulic structures of Sabanalamar and Pozo Azul belonging to the Caujerí Valley. Its general objective is to construct a series of curves that link the possible flows transferred at the wrong time taking into account the hydrological year and that this enables the correct interpretation of the ideal economic parameters for the correct operation of a small hydroelectric power plant. To materialize the previous objective, we took into account the main characteristics of the runoff and the strategies for its use, then we selected the hydrological parameters in the closure of interest. Then we continued to select an analogous basin with a hydrometric station with data greater than ten years old, we analyzed and processed the daily recorded average observations of runoff from said station. Finally, we constructed the classified flow curves for said analog basin and determined the different modular coefficients based on the observations made. Said algorithm was taken as a reference for the preparation of the classified flow curves of the Sabanalamar Transfer and the Pozo Azul Dam, which allowed us to conclude that all the flow determined in the mentioned basin, even the altered one, should not be derived. We also obtained detailed information on the different possible moments through which flows may pass in the selected closure.
