The purpose of the present study was to evaluate the hydrologic changes and the effect of runoff characteristics of a large river basin due to construction of a dam. The changes of land use and vegetation are quantified from remote sensing film taken before and after dam construction. Evapotranspiration, runoff and soil moisture were calculated using water balance equation. It was found that the albedo of watershed upstream of the dam is decreasing due to the decreasing of vegetation and the increasing of water surface and forest, and the increasing of potential evpotranspiration and soil moisture led to increasing actual evpotranspiration and runoff ratio after dam construction.
