The Impacts of Water Infrastructure and Climate Change on the Hydrology of the Upper Ganges River Basin

According to authors of this report published by IWMI, '' TMost of the river basins in India are data poor, including its iconic river – Ganga (Ganges)''.This report concludes that "various dams and barrages constructed to date have reduced mainly the flows during the dry season – when irrigation water demands are the highest. Flow regulation through dams and barrages has also changed the timing of annual extreme water conditions such as the date of minimum and maximum flows. The change in the timing of the minimum flow date is, however,affected more than the maximum flows. Future water resources development plans need to take this into serious consideration in order to avoid further detrimental impacts on the river ecology".
