Abstract: Base on the information of satellite observation (EOS/MODIS) and the meteorological and hydrological data observed by the meteorological and hydrological stations in the Kumalak River Basin, this paper analyzes the formation causes of snowmelt flood and the relations between the change of snow cover depth and the meteorological factors in the Kumalak River Basin during the period of 2002-2008, and studies the weather system and the meteorological factors resulting in the mixed and snowmelt flood in the drainage basin. The results show that snowmelt caused by high temperature is the cause of flood during the period from mid-July to mid-August. The change of 0 ℃-level height over the drainage basin in summer can be regarded as a good index of predicting flood. Snowmelt flood in midsummer is dominant in the Kumalak River Basin.
