studied and classified. Structures were selected for various condi- 

 tions of exposure, treatment, and types. Measurements and observa- 

 tions were made over a 10-year period and general conclusions pre- 

 sented regarding useful life of steel sheet piling. Measured and 

 observed data are tabulated.

 beaches has occurred. Construction procedures and structural 

 criteria are presented.
