Simulation of Stream Flow for Upper Lam Takongsub-Watershed Using SWAT Model

Netnapa Pongpetch and Pongthep Suwanwaree

Abstract—Watershed is considered to be the idea unit for water management. The Soil and Water Assessment Tool (SWAT) interfaced with ArcGIS 9.3 software (ArcSWAT2009) was selected for stream flow estimation from Upper Lam Takong, a part of the Moolbasin, in Northeastern region of Thailand. This sub-watershed has a total area of 581 km2. The model was calibrated for the year 2007-2008 and validated with observed stream flow for the year 2009. Then the model performance was evaluated using statistical and graphical methods to assess model simulation capability for the study area. The Nash-Sutcliffe model efficiency (NSE) coefficient and the regression correlation coefficient (R2) for monthly stream flow were obtained as 0.85 and 0.86 for calibration period and 0.63 and 0.92 for validation period, which showed that SWAT model can be a useful tool for water resource management in Upper Lam Takongand the bigger Lam Takong watershed.
