Abstract : An attempt has been made to give an overall idea of erosion-deposition at the Balari-Haldia-Gangra reach of the Hooghly estuary in India. The sediment transport relationships developed by van Rijn and Ackers- White have been tried. Calculation of bed-load transport has been made based on bed material sizes, flow conditions, depth and width of the channels, during 1993-97. Comparison of the results indicates the discrepancies between calculated and observed quantum of deposition/erosion to the extent of 0.6 to 1.8 times in case of an Rijn equation and 0.8 to 1.8 times in case of Ackers-White's model. Results suggest that the Haldia-Balari channel is deteriorating due to accumulation of sediment.
