Hydrodynamic and ecological 3D modeling in tropical lakes

Abstract Conservation and improvement of water quality in bodies is an important matter to maintain all its uses as well other human necessities like microclimate regulation leisure. Lakes reservoirs have a complex circulation behavior with vertical temperature profiles changes along the time, resulting differences density stratification condition. This characteristic can directly affect conditions perturbing main indicators. study aims evaluate quasi-3D models' capacity represent hydrodynamic tropical lake effects on variables that characterize quality. To achieve this objective, high-frequency monitoring data were collected, was represented model, accuracy result evaluated by applying statistical indices. The evaluation showed good agreement between field measures simulated results when compared applications. connections seen simulations analysis, which mixing events long periods perturb quality, first re-suspended bed material second blocking surface bottom exchanges. application 3D model gives reproduce reservoir spatial variability profiles, necessary constituents' distributions across column. Therefore, lakes accurately importance improving techniques.
