Some Projected Changes in River Flows due to Melting of HKH Glaciers (As reported in recent studies) IPCC TAR (2001):Increased glacier melt in the Himalayas may cause serious floods in Nepal, India and Bangladesh. World Bank (2006):Western Himalayan glaciers will retreat for the next 50 years causing increase of Indus River flows. Then the glacier reservoirs will be empty, resulting in decrease of flows by up to 30% to 40% over the subsequent fifty years. IPCC AR4 (2007):Glacier melt in the Himalayas is projected to increase flooding within next two to three decades. This will be followed by decreased river flows as the glaciers recede.
