milestone will occur approximately 2 years before the scheduled conclusion of 

 the work unit. Component models comprising the initial system are determined 

 by: (a) available models within the Coastal Engineering Research Center 

 (CERC) addressing the important physical processes, (b) other (outside CERC) 

 state-of-the-art methods for modeling these processes on a regional scale, and 

 (c) the need for having a field oriented product in the near future. The 

 framework designed for linking these models into a usable system will allow 

 for integration of more sophisticated models when they become available. Re- 

 search addressing perceived weaknesses in the system models will be conducted 

 concurrently with work done to bring the system to its initial level of 

 sophistication. 



4. Any technology created as an interim product, which can immediately 

 aid Corps field engineers and can be easily transferred to them, will be made 

 available. This report documents such a product. The Regional Coastal Pro- 

 cesses Wave (RCPWAVE) Propagation Model can be used to predict linear, plane 

 wave propagation over a "regional" area of arbitrary bathymetry. This model 

 currently forms the initial level of sophistication for the short-wave model- 

 ing component of the regional system.
