Modelación Hidrodinámica y de Calidad de Agua con MIKE 3 y ECOLab en el Embalse la Playa - Boyacá

Abstract

The reservoir La Playa located in the municipality of Tuta, Department of Boyacá, is part of the upper basin of the river Chicamocha, was built in 1967 to regulate the flow of the river Jordan and control floods in winter, Currently the reservoir does not present information on water quality and its conditions are alarming, since the waste water from the surrounding municipalities is discharged. There is a variability in the growth of the aquatic ecosystem, which has a high polluting load with high concentrations of BOD, which causes a decrease in the dissolved oxygen of the reservoir and this leads to the generation of impacts such as air pollution by the generation of bad Odors, deterioration of the ecosystem and the effects on human and animal health from the use of water for irrigation and human consumption [1]. The study of the hydrodynamic behavior of a reservoir is relevant since it directly influences the sedimentation process, one of the most complex processes that alter the water quality conditions [2]. In order to evaluate these conditions, the MIKE 3 hydrodynamic model was implemented, which represents the physical behavior of the reservoir. The model allowed to simulate water level, variations and flows in response to a variety of forcing functions, together with the ECOLab water quality module, which is the complementary tool for the analysis of water quality in water bodies [3]. Thus fulfilling the objective of the study within the evaluation in water management.
