چکیده

The hydrological models are important tools to evaluate the behavior of watersheds, helping in decision making. Thus, this study had objective evaluating performance Soil and Water Assessment Tool (SWAT) model flow simulation Ribeirão Taquaruçu Hydrographic Basin. Flow data from two fluviometric stations were used April 2013 August 2015. results sensitivity analysis indicated that most influential parameters SOL_K (saturated hydraulic conductivity soil) CN2 (curve number for condition II). Nash-Sutcliffe (NSE) functions determination coefficient (R2) indicated, calibration period, following values: -0.05 0.55 (sub-basin 1); 0.51 3), respectively. In validation presented NSE R2: 0.44 0.54 0.24 0.29 order. Considering object is responsible a large part water supply Palmas - TO program was unable simulate minimum flows adequately, considered unsatisfactory

Hydrodynamic Modelling with Soil and Water Assessment Tool (SWAT) for Predicting Dynamic Behaviour of Pesticides

The first step in the dynamic modelling of pesticides is a reliable hydrodynamic model. SWAT (Soil and Water Assessment Tool) calculates both the dynamic hydrological response and the associated diffuse pesticide supply towards surface waters. In this study, we focus on the hydrodynamic part. First, an intensive data collection for the Nil-catchment was performed. During model set-up, a reducti...
