cooperative arrangement with fthsr a>?snc:Las. The mission of producing 

 this chapter is ".s^-'med to the Research DivJsion. 



The chapter on littoral materials -Ad 11 include all information 

 available on mechanical ccnposibion, sorting, and disposition oX beach 

 and offshore sediments, in areas where data are completely lacking, a 

 li,mited amount of sampling and analysis will be undertaken. Preparation 

 of this chapter is assigned to the Engineering Division. Tlie staff will 

 be augmented for this purpose by temnora-^y implo\in'.mt of selected 

 specialists. Action has been initiated to secure consulting service 

 from L>r . W. C, Krumbein of Northwestern finivsrsity for this task. 



The chapter on littoral measurements will involve compilation of 

 all applicable iic; from prior surveys such as shore line chansres, 

 offshore changes, computation of volumes of accretion or erosion rates 

 where possible or compilation ci' such iata previously computed. Pro- 

 duction of this chapter is assigned lo t?i3 Reports and Publications 

 Division^ which also has editing and processing responsibility for all 

 chapters of the report. 



The summary and conclusions will be a joint effort of the staff and 

 will be subjected to critical review b;/ all participating authors of other 

 chapters. Publication of each complete report will be subject to ap- 

 proval by the Board. Individual chapters other than the summary and con- 

 clusions may be published as 02 ;hnical memoranda without Board approval 

 in cases where completion of all chapters would be lelayed for an 

 appreciable time. The reports when completed will pjr-nit much oroader 

 consideration of the long range effect of erosion problems in local 

 areas and of remedial measures proposed to correct them, They will fill 

 an acute need for authoritative data w?!ich can bt; supplied in response to 

 the numerous requests for such data. They will for'n a foundation of shore 

 information of broad scope which can be built upon as information is 

 gained. 



The Research Program 



The research progra^^ of the Reach :,rooic;n Bo--jrd is direcusd Lov/ard 

 obtaining a more correct and thoroua-h un lerstanding of beach processes 

 and the effect on these processes of various types cf prctecoive works, 

 leading to the design of more effective and more economical plans of 

 shore protection and improvement. 



In order to formalize the research program, the various factors 

 (excluding economic factors) which are believed to play a significant 

 part in the under st'iruinr and solution of beach erosion problems have 

 been classified under nine basic headings and 36 sub-headings as follows;
