The present project is part of a coherent effort to enhance and verify the nearshore modeling suite Delft3D and aid its transition to the operational Navy forecasting centers. Our present focus is on verification of the model and on the development of a forecast system within which Delft3D serves as the primary computational engine. The resulting system can be used for semi-automated, highly simplified model operation on-scene, with automated incorporation of boundary and input conditions and grid resolution based on model behavior and bathymetric complexity. The objectives of the project are: 1) Accomplish initial development of the forecast system. 2) Test and evaluate modeling system. 3) Determine and evaluate model sensitivity to variations in the bathymetry and other environmental input. 4) Validate the improved model system and identify further areas for improvement.
