a_. Sea-to-swell transformations are considered as separate 

 processes, and the two wave populations are independent. 



b^. Swell acts as a unidirectional, monochromatic wave. 



c_. Shoreline has straight, parallel bottom contours. 



d^. No extra energy sources were added to existing Phase II 

 conditions . 



These assumptions appear reasonable since hindcasted wave heights compare 

 well with gage measurements.

20. The hindcasted Phase III data included for each storm and locality 

 differ from that reported by Jensen (1983) in two ways: (a) wave heights were 

 computed for a water depth of 9.15 m (30 ft), 1 m shallower; and (b) the sea 

 and swell conditions have been combined. Also, a special hindcast run was 

 made for Misquamicut because of the natural sheltering offered by Long Island
