Three Dimensional Shallow Water Adaptive Hydraulics (ADH-SW3): Waterborne Vessels
ENGINEER RESEARCH AND DEVELOPMENT CENTER VICKSBURG MS COASTAL AND HYDRAULICS LAB
Pagination or Media Count:
This Coastal and Hydraulics Engineering Technical Note CHETN describes the implementation and testing of waterborne vessels induced pressure and stresses into the three dimensional 3D shallow water module SW of the Adaptive Hydraulics AdH numerical code. A description of the inputs required by the user is also provided and serves as the user s guide. The movement of a vessel through a water body produces currents and waves. Maynord 1996 provided a general description of these waves and currents and provided analytical tools to describe the effects of these currents on the hydrodynamics of the water body. Stockstill et al. 1999 showed that by applying the pressure imposed on the water surface by the vessel into a numerical model, these currents and their far-field effects can be accurately simulated. In this technical note the authors expand the two-dimensional 2D shallow water implementation presented by Stockstill et al. 1999 into the 3D shallow water realm.
