An analysis of the results obtained for winter surveys during fis- 

 cal years 1956, 1957, and 1958 on the problem of erosion and washout of 

 the Niigata coast is presented. The paper includes a description of the 

 data, and the mechanism of erosion and washout on the west coast of 

 Niigata, which was the main objective of the survey.

Coastal retreat due to erosion by the sea is experienced along 

 several segments of Sri Lanka's coastline. This report discusses the 

 erosion experienced on a section of the southwest coast, between Colombo 

 and Dondra Head. Here, dense human inhabitance compounds the gravity of 

 the problem as settlements, cultivable land, public installations, and 

 scenic tourist beaches are threatened by the sea.
