ABSTRACT:
This
research was conducted in the upstream watershed of the Mae Yom Irrigation
Project, which was located in the Upper Yom River Basin in Phrae Province,
Thailand. The most common troublesome in this area is flood and drought and leads
to poor water management by difficult river flow forecasting to an existing
large weir without upstream dam. The Soil And Water Assessment Tool (SWAT)
model was applied for the simulation of the hydrological system and predicting
the daily river flow to the upstream weir during flood season in 2006 and 2011
as for simulating and comparing with observed data. The results were fitted to
the observed data with Nash and Sutcliffe efficiency (NSE) of ?0.65, and root
mean square error (RSME) of 228.0 whereas the mean inflow discharge during wet
season in both years was 173.3 cubic meters per second, respectively.
