Abstract
The impact of climate change on river flow in Thailand is analyzed by feeding future climate projection data into a distributed rainfall-runoff model. The projection data used consists of daily hydrologic data downscaled by hourly precipitation for the present climate (1979-2003), the near future climate (2015-2039), and the future climate (2075-2099), which were simulated by a 20km spatial resolution general circulation model (MRI-AM20km) developed by the Meteorological Research Institute, Japan Meteorological Agency. It is found that a change of river flow appears at the tributaries of the Chao Phraya River. The change pattern differs according to location, and it is expected to decrease of water resources at the Pasak River basin. Thus, we develop a water resources assessment model at the Pasak River basin, which includes a distributed hydrologic model, a dam reservoir water storage prediction model, and a plant growth model for rice production assessment.
