Công trình cống Xẻo Rô - một loại kết cấu công trình mới ở đồng bằng sông Cửu Long

Abstract

The Mekong Delta (MK) is a young floodplain located in the Lower Mekong River with a low and flat terrain, water resources abundance, and a coastline of more than 700km which is influenced by the semi-diurnal tidal and diurnal tidal regimes in the East and West Seas, respectively. The major objective of the irrigation systems in MK is to control the water resources and at the same time secure favorable waterway navigation requirements. Therefore, most irrigation infrastructure built on large canals and rivers or important waterways must have to arrange separate culverts and locks. Cong Xeo Ro, belonging to the Cai Lon - Cai Be irrigation system, is the first project in MK that integrates a structural arrangement that both control the water sources and secure waterway navigation requirements when needed. This article introduces analyses, evaluation, and proposes technical solutions for this integrated irrigation infrastructure.
