Applications of Dredging and Beach Fills in GenCade

This Coastal and Hydraulics Engineering Technical Note CHETN provides guidance for simulating dredging of inlet shoals and associated placement of beach fills in GenCade. Applications of beach fills and dredging represent the majority of GenCade simulations and alternatives. This CHETN describes basic theory, setup, and applications of beach fills and dredging and is intended to explain how GenCade can be used to help District users answer questions about these types of applied engineering studies. Idealized applications of a single beach fill, an inlet with dredging and placement updrift and downdrift, and an inlet with dredging but sand removed from the model are described. Present model limitations are also discussed. The reader is referred to Frey et al. 2012, 2014 and Munger and Frey 2015 for additional information about the GenCade model.
