Development of the Long Caisson Type Vertical Breakwater
The width of the caisson of a breakwater is calculated based mainly on the wave force expected to act on the caisson. IN this calculation, the assumed wave force is the peak wave force...

A Study of Political Decision Method for Remote Island's Environmental Management?Patterns of Remote Islands and a Political Goal
Remote islands are handicapped in their incomes and living conditions, because they are surrounded by oceans, the area is rather small, and also they are far from economic and cultural...
