NGHIÊN CỨU ĐỀ XUẤT LỰA CHỌN VỊ TRÍ XÂY DỰNG CÔNG TRÌNH CỐNG SÔNG LAM ĐỂ NGĂN MẶN, GIỮ NGỌT VÀ CẢI TẠO MÔI TRƯỜNG

Abstract

The Lam River culvert at the downstream of Ben Thuy bridge in Hung Hoa commune, Vinh city, Nghe An province and Nghi Xuan town, Ha Tinh province were selected as a work solution to actively respond to the situation of saline intrusion due to the effects of climate change, sea level rise, ensuring active prevention of salinity (increasingly penetrating into the inland), fresh water for farming and supply of water for the Lam's downstream  in Nghe An and Ha Tinh. Determining the location, size of the works is a difficult problem. Based on the two design routes proposed by the design consultant, the results of the study, calculating the hydraulic model to select suitable locations for constructing the works were summarized in this paper.
