Impact of Glaciated Extent on River Flows: a case study of Chitral Watershed (original) (raw)

Abstract

The phenomenon of global warming holds immense fear almost for every natural process on going in the universe. One of the major impacts of global warming is climate change. The changes in climatic conditions can hold deep impacts on water resources of the world. In Pakistan where diverse weather conditions subsist, the effects of climate change can be more vital. The adverse effect of global warming is increase in temperatures of near earth’s surface. Global data from 1880 to 2009 show that average temperatures have raised from around -0.3oC to 0.4oC that directly threats the glaciers and waters of the globe. This global warming can also have a strong impact on river flows in Pakistan. This may be due to the reduction in glaciated extent and snow at a higher rate and changes in precipitation patterns. Glaciers in Pakistan cover about 13,680 km2 which is 13% of mountainous regions of upper Indus Basin. The high melt rate of glaciers and increase in temperature depict that the glacier...
