Cohesive Sediment Transport. II: Application

Abstract

Typical engineering applications involving cohesive sediments in tidal water bodies including bays, estuarial navigation channels, small harbor basins, piers, and wharves have been cited. Reference has been made to problems in reservoirs and in the muddy coast environment. Techniques for prediction of estuarial sedimentation include field methods, physical and numerical modeling, and hybrid modeling which optimally combines physical and numerical modeling approaches. In many cases simple, zero‐dimensional modeling yields results of acceptable accuracy. Three‐dimensional numerical models have recently been developed for analyzing situations in which the complex structure of flows and associated sediment motion cannot be simplified. Further progress in improving the accuracy of prediction of sedimentation rates can be made by better understanding the basic laws governing cohesive sediment behavior, and by developing new strategies and instrumentation for data collection.
