For comparison, the September 1938 storm surge, idiich was used as 

 a basis for storm surge studies by Texas A & M Research Foimdation and 

 Waterways Experiment Station model studies, follows:

Significant wave heights in the design hurricane have been fur- 

 nished by the Beach Erosion Board at proposed barrier locations in 

 Narragansett Bay. In general, they are greatest in the Lower Bay 

 and diminish in size up the bay to a minimum at Providence. The 

 following tabulation summarizes significant wave heights and periods 

 with wind from the south.

Investigations to determine the effects of proposed barrier plans 

 on hurricane-tide elevations throughout Narragansett Bay are based 

 mainly on hydraulic model tests.
