CLASSIFICATION OF SEAWALLS AND THEIR FAILURE: AN OVERVIEW
Journal Title: Academic Research International - Year 2018, Vol 9, Issue 1
Abstract
The effects of seawalls on beaches and coastal dynamics have not been well documented in the literature. The purpose and function of coastal structures, especially seawalls, have often been misunderstood, as in some cases, seawalls lead to coastal erosion, contrary to protecting the shoreline for which they are generally constructed. Seawalls have been reportedly causing changes in the nearshore process, specifically the sediment dynamics by affecting the onshore/offshore and, to some extent, the longshore sand transport. Therefore, it becomes pertinent to understand the basic guidelines for the construction of a seawall to make sure more informed decisions are made on their installation. This paper discusses the effects of seawall on beaches, gives guidelines for the construction of a rubble-mound seawall and the various factors contributing to the failures of seawalls.
