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