THE INFLUENCE OF MORPHOMETRY OF THE SURFACE RESERVOIRS IN EVAPORATION LOSSES IN POTIGUAR SEMIARID REGION
Surface reservoirs. Evaporation. Morphometry.
Superficial reservoirs are essential for water supply, food production and various economic activities in semi-arid regions. However, in these regions, due to the very dry climate characterized by rainfall irregularity and high temperatures, the high evaporation rates interfere significantly in the efficiencies of the surface reservoirs. Meanwhile, the morphometry of the reservoirs has been frequently recognized as one of the most important characteristics that influences the volume evaporated in the reservoirs. Thus, using multiple linear regression analysis, this work presented the morphometric parameters most associated to the storage efficiency of the reservoirs and formulated a predictive statistical model of the annual evaporated volume rate of the reservoirs with a 67% adjustment.
