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 

 improvements of the entrances at the mouths of rivers 

 and inlets (Section 5, Public Law No. 4.09c 74 th Con- 

 gress). 



do Reports on shore protection of Federal property 

 (authorization by the Chief of Engineers ) c 



Of these types of studies, cooperative beach erosion studies 

 are the type most frequently made when a community desires in- 

 vestigation of its particular problem. As these studies have, 

 consequently, greater general interests, information concerning 

 studies of specific localities contained in these quarterly bulletins 

 will be confined to cooperative studies. Information 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 cooperating agency. 

 Information concerning the initiation of a cooperative study may be ob- 

 tained from any District Engineer of the Corps of Engineers. After a 

 report on a cooperative study has been transmitted to Congress, a 

 summary thereof will be included in the next issue of this bulletin. 

 A list of completed cooperative studies and of those now in progress
