Software Development for Producing Standard Navy Surf Output from Delft3D

Abstract

The Delft3D modeling system, developed by Delft Hydraulics, is a comprehensive coastal hydrodynamic modeling system, capable of simulating hydrodynamic processes due to waves, tides, rivers, winds and coastal currents. Delft3D produces two-dimensional time-dependent forecasting output for many nearshore wave and flow parameters. But it does not produce the operational surf forecasting parameters as specified in the Joint Surf Manual. The standard surf parameters include maximum and significant breaker heights, breaker type statistics, percent of breaking, surf zone width, number of surf lines and modified surf index (MSI). Subroutines from Navy Standard Surf Model (SURF 3.2) are adapted and refined to compute these surf parameters from Delft3D output. This report describes input and output files and the software structure.
