AN EXPERIMENTAL STUDY ON BEACH TRANSFORMATION DUE TO WAVES UNDER THE OPERATION OF COASTAL DRAIN SYSTEM

Abstract

The performance of a coastal drain system was investigated experimentally. When the drain pipe was buried in the seaward area of a shoreline, the system was most effective. When the discharge is large, the drain system could accumulate a large amount of sediments on a beach face even under erosive wave conditions without drainage. The flow toward shore induced by drainage seemed to play an important role.
