CADD Surface Modeling for Input to Wave Response Numerical Investigations

Abstract

This report documents and describes the procedure to utilize computer-aided design and drafting surface modeling to provide input data to a wave response program. Specifically, a surface model created using Intergraph Corporation's Engineering Site Package (ESP) was used to feed data into HARBD, a wave response program. The WES Coastal Engineering Research Center (CERC) was asked to numerically model the effects of proposed site plan and breakwater modifications at Kawaihae Harbor on the island of Hawaii. CERC uses HARBD, a program from the ECPL that predicts harbor wave response. The program requires that the harbor surface be described by triangular elements with xy coordinate data at the vertices and a corresponding water depth at the element centroid. The size of the triangles is dependent upon wavelength and was limited to 20 ft* for this case. (kr)
