From the Past to the Present of Coastal Protection Measures at Saeng Chan and Suchada Beach, Rayong: Physical Changes and Perspectives of Locals, Public Agencies and Academics in Related Fields

Abstract

Objectives: This article aims to study the changes in the area around the hard-structured coastal protection at Saeng Chan Beach and Suchada Beach, Rayong province from 2000 to 2019.

Methods: The actual physical changes were detected.  Discussions with the locals, relevant agencies, and academics in related fields were also considered. 

Results: It was found that the trend of change in the coastal line was of a spatial pattern: stabilized – eroded – deposited. Moreover, offshore breakwaters had led to increased erosion depths. After the entire construction was completed, the depth had increased continuously. Local volunteers, agencies, and academics remarked that the erosion caused by the construction of a nearby port was damaging the environment and livelihoods of people in the area. The academics stated that the structure may pose both short term and long term disruption to the natural balance. It is worth noting that the local volunteers were satisfied with the coastal protection as it can immediately solve the problem of erosion.

Application of this study: The research findings contribute to decision-making in coastal management and environmental impact assessments, supporting the development of efficient coastal areas and fostering the involvement of stakeholders in addressing coastal erosion issues in the studied and other areas.
