128. The reviewed MSBWT model has a number of potentially attractive 

 features, including use of a probabilistic approach to erosion quantities, 

 provision for overwash, and a duration dependency based on the rise time of 

 the peak surge. Though it is too complex and undeveloped for the present 

 needs of FEMA, this model may be useful in the future. 



129. Because none of the models can adequately account for the normal 

 alongshore variation in profile changes, use of the variability factor (see 

 Part II) as a multiplier of the predicted erosion quantities will help ensure 

 that reasonable erosion estimates are obtained.
