Another step in drawing up the research program of the Board is a 

 statement, in order of priority, of the ten questions or problems most 

 frequently encountered in specific shore protection studies for which 

 adequate, quantitative answers are not generally available based on the 

 present knowledge of beach processes. These questions are listed below.
