More than ever, the U.S. Navy has a need for accurate depictions of surf conditions in order to plan and conduct operations such as amphibious landing, mine sweeping, and special applications. An important role in bringing about this accurate littoral picture and a rapid environmental assessment is the use of a sophisticated modeling system capable of providing wave, current and sediment transport depictions, critical for planning. The latest technology to meet the challenge is Delft3D, developed by Delft Hydraulics in the Netherlands. This modeling system that runs on a laptop personal computer is a compact but powerful suite of models controlled by an integrated system of modules and is highly configurable using a set of user-friendly set-up menus. Given accurate bathymetry, sea state, tides and local winds, Delft3D can produce in short order a 3-dimensional forecast picture of currents and sea state of the nearshore zone. Descriptions on how Delft3D is used in a typical scenario will be given. The comparison between Delft3D results and wave and current data from the Duck94 field experiments will be shown.
