BEACH EROSION STUDIES 



The principal types of beach erosion reports of studies at specific 

 localities are the following; 



a. Cooperative studies (authorization by the Chief of 

 Engineers in accordance with Section 2, River and 

 Harbor Act approved on 3 July 1930). 



b. Preliminary examinations and surveys (Congressional 

 authorization by reference to locality by name). 



Co Reports on shore line changes which may result from im- 

 provements of the entrances at the mouths of rivers and 

 inlets (Section 5 S Public Law No. 409 s 74-th Congress). 



d„ Reports on shore protection of Federal property 

 (authorisation by the Chief of Engineers). 



Of these types of studies, cooperative beach erosion studies are the 

 type most frequently made when a community desires investigation of its 

 particular problem. As these studies have, consequently greater general 

 interest, information concerning studies of specific localities contained 

 in these quarterly bulletins will be confined to cooperative studies. Infor- 

 mation about other types of studies can be obtained upon inquiry to this office. 



Cooperative studies of beach erosion are studies made by the Corps of 

 Engineers in cooperation with appropriate agencies of the various States 

 by authority of Section 2, of the River and Harbor Act approved on 3 July 

 1930. By executive ruling the cost of these studies is divided equally 

 between the United States and the cooperative agency. Information concern- 

 ing the initiation ©f a cooperative study may be obtained from any District 

 Engineer of the Corps of Engineers. After a report on a cooperative study 

 has been transmitted to Congress, a summary thereof is included in the next 

 issue of this bulletin. A list of cooperative studies now in progress fol- 

 lows the summary.
