Abstract

This paper presents the results of laboratory investigation on the statically stable reshaped berm breakwater in shallow water and intermediate wave action. A new model configuration has been proposed with five layers of armor stones in the primary layer at the berm portion, and below the berm portion, and three layers above the berm portion. Armor layer thickness has been increased to account for initial reshaping. As equivalent surf similarity parameter increases and wave steepness decreases both the profile parameters, the recession of the berm and eroded area of the berm decreases. The wave period has large influence on the recession of berm width and eroded area of the berm and greater the stability of the structure lesser will be the influence of wave period.

Item Type: Conference or Workshop Item (Paper)
Uncontrolled Keywords: Berm breakwater; recession of berm; eroded area of berm; profile parameter.
