Abstract:

Shoaling rates at three predominant areas of sedimentation in the Hooghly River estuary, India, have been predicted using a sediment transport model run on an IBM compatible microcomputer. The one-dimensional model uses a settling function to determine the amount of sediment which deposits in an estuarial channel segment. A two node, finite difference schematization is used to simulate a settling basin, with a node located at each end. The Einstein methodology is used for determining the bedload and suspended load transport rates. The average amount of deposition, represented as a decrease in the depth in the shoaling area over a single time-step during model simulation is determined by solving for the time-averaged difference between the amount of sediment transported out of and into the basin.
