Đánh giá khả năng thoát lũ của sông Hồng khi nạo vét, hạ thấp cao độ các bãi sông

Abstract

In order to increase the flood drainage capacity of the Red River, the dredging and lowering solutions of river floodplain have been proposed, but the theoretical and practical basis to prove also as assessed the effectiveness of this solution is still unclear. The content of this article inherits some previous research results but has updated the new model (MIKE 21FM) and new parameters of geometry, morphological form of the typical river section, thereby giving the results more comprehensive research results to evaluate the effectiveness and limitation of this solution to improve flood drainage capacity of the Red River.
