9 ABSTRACT (Continue on reverse if necessary and identify by block number) 



This report examines the feasibility of accounting for the processes of erosion and 

 overwash in the determination of coastal high-hazard flood zones, or V-zones. Included in 

 the report are discussions of the merits and limitations of existing theoretical, empirical, 

 and parameterized models for predicting beach profile change and dune erosion. Also included 

 are discussions of the variability found in measured storm changes and an extensive review 

 of the overwash literature. 



Of the models evaluated, two dune erosion models were found to produce reasonable dune 

 erosion estimates. One model (Kriebel 1982) is based on the assumption of uniform energy 

 dissipation in the surf zone and the concept of an equilibrium profile shape which responds 

 jto a rising water level by shifting upward and landward. The other model (Vellinga 1983) was 

 [developed for use on the coast of The Netherlands and is based on a profile shape equation 

 developed from an extensive series of large scale physical model tests.
