Abstract

A comparison of data on annual sediment loads recorded along the Krishna and Godavari Rivers showed consistently lower sediment quantities at the locations downstream of dams than at their upstream counterparts. Reports based on bathymetric surveys revealed considerable reduction in the storage capacities of reservoirs behind such dams. Apparently sediment retention at the dams is the main reason for the pronounced coastal erosion (revealed by the analysis of multi-date satellite imagery and maps) along the Krishna and Godavari deltas during the past four decades, which is coeval to the hectic dam construction activity in these river basins
