20. ABSTRACT fCozrtftnje fln revermm sftfo ft rtame-aaary and. idenilly by block number) 



An implicit finite-difference, n-line numerical model is developed to pre- 

 dict bathymetric changes in the vicinity of coastal structures. The wave 

 field transformation includes refraction, shoaling, and diffraction. The model 

 is capable of simulating one or more shore-perpendicular structures, movement 

 of offshore disposal mounds, and beach fill evolution. The structure length 

 and location, sediment properties, equilibrium beach profile, etc., are user 

 specified along with the wave climate.
