| Research Abstract |
Using several GCM outputs developed by the Meteorological Research Institute in Japan and so on, streamflow in the Southeast Asian region was projected using a distributed river flow routing model with the kinematic wave flow approximation. The projected streamflow was analyzed spatially and statistically, and catchments with changing streamflow regime were detected. It was found that the annual mean flow and the annual maximum flow at the Irrawaddy River basin showed significant increase. Future irrigation water demand in Thailand was also estimated by a land surface model coupled with a crop growth scheme using MRI GCM output.
