Giải pháp phát triển bền vững bờ biển vùng cửa sông Cửu Long: Nghiên cứu điển hình cho bờ biển Trà Vinh

Abstract

In recent years, erosion has become common in most of the coasts of the Mekong Delta. Coastal hard infrastructure have not yet achieved sustainable protection. Applying to the typical study area, which is the coast of Hiep Thanh commune, Tra Vinh province, the article analyzes the factors affecting coastal erosion including: Wave - tide - current regime; the process of transporting sediment along - across the shore; Coastal hard infrastructure. The proposed solution for shore protection works is a system of T-wave reduction dykes, the distance between the two dykes is 50, 80, 130m, respectively. Mike 21/3 FM mathematical modeling software is used to calculate the efficiency of the construction scenarios
