Erosion caused by coastal structure

Abstract

Coastal structure such as jetties, groins, sea walls, breakwaters, etc. along the coast can alter the shoreline and morphological structure of coastline. Presence of the coastal structure gives impact like sediment trapping on upstream side of the structure and causing shore erosion along adjacent shorelines. Therefore, this paper presents attempts to describe the coastal erosion process effected by a different kind of coastal structure. Generally, it takes time to notes the impact of coastal erosion, therefore several methods are adapted to identify the erosion by surface sediment sampling and beach profile measurement. These measurements are conducted by conventional and high-technology method such as manual surface sediment sampling, Real-Time Kinematic (RTK) GPS, LiDAR and UAV. In terms of analysis, these methods can be approach with variable techniques and applications. However, this review paper briefly described the commonly used technique and application in finding the result of eroded coastal.
