The low-lying plains of Nepal and coastal areas of Bangladesh, for example, will to start with enjoy an building up in water ranges, Thakuri mentioned — a state of affairs that might result in extra flooding. Through the years, on the other hand, the location would possibly opposite. For the reason that glaciers would now not hang as a lot ice and snow, he added, rivers downstream may obtain much less water within the dry seasons.
