Abstract

A new longshore sediment transport laboratory facility for conducting three-dimensional moveable-bed experiments is being developed by the U.S. Army Engineer Waterways Experiment Station, Coastal and Hydraulics Laboratory. This paper focuses on the problem of designing the pumping capacity for an external longshore current recirculation system, designed to minimize adverse laboratory effects created by the updrift and downdrift lateral boundaries of the new facility. A review of longshore current recirculation systems used in other laboratory facilities is presented. The numerical model NMLONG is used to predict the magnitude and cross-shore distribution of the wave-driven longshore current that will be generated during experiments in the new facility. This paper concludes with a performance curve that defines the required pumping capacity of each of the individual pumps in the longshore current recirculation system.
