Island, New York, and the North Carolina-Virginia state line was covered. 

 Aerial photographs of the coast immediately following the storm were ob- 

 tained, and it is planned to repeat these at later intervals in the year 

 for comparative purposes. Further field data will be collected to evaluate 

 the emergency repair work which has been carried out since the storm. 



(o) Evaluation of a Stream Outlet Structure (Sand Plug Opening Device) 



A laboratory study was made for, and a report prepared and submitted 

 to, the U. S. Soil Conservation Service on the effectiveness of a sand plug 

 opening device. The device was designed by Soil Conservation Service 

 Engineers in an attempt to have stream floods break through wave formed sand 

 plugs in the seaward exits of streams before the stream floods reach an 

 elevation high enough to cause damage inland of the sand plug. In general, 

 the stream flood cannot be allowed to rise high enough to overtop the sand 

 Plug. 



A 1:20 scale model of the proposed structure was made and tested in a 

 laboratory wave tank. The sand plug opener worked as predicted; however, 

 the study left some doubt as to whether the device would cause the sand 

 plug to erode quickly enough to prevent flooding when the stream flood rose 

 from +2 feet MSL to +6 feet MSL in 13 minutes. Flooding was assumed to 

 occur at stream elevations greater than +6 feet MSL.
