Scour at the foot of vertical homogeneous crib-style walls, which 

 were used as models for detached breakwaters, and the rise of mean water 

 level in the shoreside region of the breakwaters were experimentally 

 investigated. The results were compared to some field data.

Model studies and analyses of oceanographic and littoral drift data 

 were undertaken to advise Howe India (Private) Ltd. on littoral drift, 

 siltation, and shore erosion problems to be encountered during and after 

 the construction of Visakhapatnam outer harbor project. Distorted fixed- 

 and movable-bed models with a horizontal scale of 1:300 and a vertical 

 scale of 1:80 were calibrated to reproduce the integrated net effect of 

 an average southwest and northeast monsoon season. Experiments were 

 conducted to assess and predict seasonal changes resulting from the 

 construction of breakwaters under normal and extreme conditions, Recom- 

 mendations were made concerning breakwater and sand^-trap location, shore 

 protection, dredging, and disposal of dredged material.

Sand tracer studies were conducted at five locations along the 

 southern California coast (Goleta Point, Trancas, Santa Monica, Hunting- 

 ton, and LaJolla) . Tests were conducted at 4- to 6-week intervals at 

 each site for 1 year. Additional tests were conducted on the prograding 

 shoreline behind the detached breakwater at Santa Monica, Contour maps 

 of tracer movements are given for each significant test.

Basic principles of the nature of beaches and processes that act to 

 modify them are considered for the present coastal development demands, 

 A working hypothesis is developed that applies the principle of the
