Abstract: Many techniques have been used in the past to predict the effects of channel enlargement on channel shoaling. These range from rule-of-thumb predictions to elaborate physical model investigations. During the past few years, there has been progress in the use of numerical models or combined physical and numerical model (hydrid studies) for making these predictions. Empirical techniques and analytic solutions have been used extensively and provide valuable easily obtained solutions; they are, in most cases, scientifically based. This paper reviews and comments on these techniques. Refs.
