A Review of Studies on Submerged Berms

Abstract:

An overview of the latest research progress on the interaction between submerged berms and waves is given from two aspects， the evolution of submerged berms under the effects of waves and the wave dissipation effect of submerged berms. Classic experimental studies of the interaction between submerged berms and waves are reviewed， and their research background， scaling criteria， and main conclusions are introduced. The development process and core idea of “process-based profile evolution model”， which is suitable for the simulation of medium- and long- term evolution of submerged berms， are expounded. Suggestions on the engineering application of submerged berms are given from the aspects of longshore length， nourishment location， and lifetime design. The limitations of conclusions and methodologies of existing studies are discussed， and future research prospects are proposed.
