Wave Forces and Moments on Heavily Overtopped Vertical Current Deflection Dike

摘要

Irregular wave forces on a heavily overtopped thinned-wall vertical current deflection dike were measured during a series of laboratory experiments. The purpose of the experiments was to obtain site-specific engineering values for use in design of a dike located at the mouth of the Mississippi River and to develop generic design guidance for heavily overtopped vertical walls. Predictive equations for the root-mean-squared shoreward- directed peak total force and associated moment arm were developed in terms of the incident wave momentum flux and relative wall height.
