level third level fourth level fifth level 8 the complicated reaction of runoff forming zone and runoff dissemination zone to the recent climate changes and anthropogenic impacts takes place. sources of the mountain rivers feeding: a seasonal snow cover melting, historical accumulation of ice and firn in the glaciers, rains are very sensitive to change of climatic parameters seasonal snow plays a key role in the feeding of the rivers in the aral sea basin. some reduction snow supplies in the basins most of all rivers is observed climate change impact on water resources of aral see basin 9 glaciological observations were run in the runoff formation zones since 1957. the glaciological observations were practically stopped during last 10-15 years. during 1957 – 1980 the pamir-alay glaciers lost 113 km3 (19%) of their water supplies. the lost raised up to 14% more of supplies by 1957. glaciers lost will be …
