Complete Oceanographic and Atmospheric Master Library Documentation of theShallow-Water Wave Refraction and Diffraction Model

摘要

Accurate estimates of wave conditions have become increasingly critical to Navyoperations in the coastal regions. In the shallow water, wave propagation is affected by many dynamic processes, including shoaling, refraction, diffraction and energy dissipation. The existing RCPWAVE wave model in the Navy-Standard surf model was developed for open coast with slowly varying bathymetry. It cannot handle certain coastline configurations such as those include islands or peninsulas. It also has a serious numerical instability problem. The more recently developed REF/DIFi wave model has a more robust formulation and does not suffer from the same limitations. REFIDIFi has been evaluated and validated for Naval applications. In this report, all three OAML documents, i.e. software requirements specification (SRS), software design document (SDD) and software test description (STD) are included.
