Abstract

The effects of Climate Changes (CC) on the hydrologic system in the Lam Takhong Basin located in northeastern Thailand were determined using Soil and Water Assessment Tool (SWAT). The hydrologic SWAT model was set up with land use and soil data of 2002 and observed flow and weather data during 1999-2000. The model was calibrated and validated against observed flow data during 2001-2009 and its CC scenario with input weather data during 2010-2065 was simulated. The results showed that changing climate over the 56-year period appeared to affect both water yields and flows. Water scarcity will tend to take place across the Lam Takhong River Basin in the near future. Longer periods of severe droughts and floods might occasionally occur, particularly downstream. Therefore, it is critical to prepare specific management measures to mitigate climate change-related impacts in the river basin.
