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.
