Abstract: 

Global warming and climate change has caused serious impacts on water resources of the world, including the glaciers with reducing their surfaces and volumes. Surface and volume decreasing of the glaciers, could have the serious impacts on the discharge of the glaciers rivers downstream as well the soil erosion of watersheds. The increasing amount depends on the local and regional conditions. Changing in the rainfall amount, land using, vegetation covers and erosionable potential could influence the rate of river discharge and watershed erosion. In this paper, the impact of climate change on the Sardabrood river in the west part of the Challoos city in the North of Iran has been studied with statistical methods for a fifty years period (1958-2008). In this regard, the Hodric-Prescott filter as well as regression method, for investigation the randomized and non-randomized trends of the discharge and sediment. The results showed that the discharge and sediment trends increase in this glacier watershed. The general conclusion is that sediment increase by increasing the discharge, and indicates further erosion in the basin.
