13. The most- investigated effect of detached breakwaters is the 

 relationship between project accretion, in particular, morphological response 

 (salient or tombolo) , and structural parameters. Similar simple relationships 

 between structure length and distance offshore have been proposed by various 

 researchers .

14. Based on observations of beach response at the 434-m-long single 

 detached breakwater at Venice in Santa Monica, CA, Inman and Frautschy (1966) 

 observed that pronounced accretion did not occur for the following condition:
