A Method to Forecast Sedimentation Rates Resulting From the Settlement of Suspended Solids within Semienclosed Harbors

摘要

When a semienclosed harbor is planned for an area where sediments may enter the harbor in suspension, it is desirable to forecast the rate at which those sediments will be deposited. A method to make such a forecast is presented in this report. The harbor shoaling rate (sediment accretion) is the dependent variable. The method is applicable to situations where the harbor is almost totally enclosed; bedload transport is negligible; deposition is nearly uniform throughout the harbor; sediment will not be resuspended (once deposited); and tide or river stage rise causes currents which move water and suspended sediment into the harbor.
