(b) the slo"wer moving storm, which gives a 

 lower crest but a greater volvime, and 



(c) the stalled type. 



b. Negotiations with the Navy . 



(1) Decisions on the ininimtun size of navigation 

 openings acceptable to the Navy in the light of protection 

 requirements and strategic considerations. 



(2) Investigation of the need for traffic control 

 and construction and maintenance procedures. 



c. Model tests and analytical studies . 



(1) Additional tests of barriers under flood condi- 

 tions with emphasis on (a) openings desired by the Navy; (b) 

 the most effective shape of the barriers j and (c) surges having 

 a lower flood crest but greater voliime than the design flood, 



(2) Tests on sedimentation, tidal flushing and 

 salinity. 



(3) Analytical studies of termperature changes, 

 based upon the salinity tests in the model. 



d. Foundation investigations . Deep water borings and 

 sampling at the East barrier site, for correlation with the 

 seismic explorations and for testing. Borings at the VJest barrier 

 site to supplement the boring records relating to the Jajnestown 

 Bridge, 600 feet to the north. 



e. Pollution . Studies of flushing rates and the effect 

 of barriers on pollution of the bay waters. 



f. Fish and wildlife . 



(1) Conpletion of the inventory-type studies now in 

 progress of existing biological conditions, and shellfish and 

 finfish, 



(2) Studies of the bay as a spawning and nursery area 

 for oceanic fish species. 



(3) Studies of the tolerance of various species to 

 changes of termperature, salinity and the like.
