Curvas guías de operación en el control eficiente del embalse Sixto Durán Ballén para gestionar sustentablemente el patrimonio hídrico

Abstract:

The operating guide curves (volume/time) of a reservoir, help to establish an order in the filling and evacuation period. Because of this, it aims to evaluate the relationship between operating guide curves and Sixto Durán Ballén reservoir control. Using information retrospective was possible to obtain prospective data using deductive-inductive method, and also was able to analyze historical information and simulate it in time. It was necessary using the following software: Global Mapper 16, ArcGIS 10.4.1, AutoCAD 2014, for the treatment of the shapefiles and satellite imagery (DEM), and Excel for statistical analysis of the historical information. This helped to obtain an extension of 428,50 km2 of the basin contributor of the reservoir in study, in which 4% represents the storage area and this in turn stores 228,78 hm3 to the height 66 m.a.s.l., collecting annually an average of 1038,43 hm3 of precipitation, of which 22 hm3 get evaporated and 437 hm3 is evapotranspirated, so by applying the formula of water balance and adding the different contributions of input and output was realized a schema in the Stella program, simulating three scenarios (dry, rainy, average), giving the appropiate operating guide curves for each scenario. Therefore, the operating guide curves that would simulate in a time and space will be closely associated to the timing of the water balance.
