The experimental study on waterway regulation for the Xialong shoal of Hongshui River

The Xialong shoal, which lies in the upstream of the Hongshui River, is one of the important shoals with the curve and shallow characteristic. Combining with the model test result on waterway regulation for the Xialong shoal, the properties of the shoal and the conditions of the constructing waterway is analysed in this paper. By adopting such engineering measures as dredging, cutting the snout of the shoal and exploring the reef, the navigation channel is normalized, the navigation depth is increased, the gradient ratio is reduced, and the flow condition is improved. Then the problems obstructing the waterway have been effectively solved. The favourable waterway conditions have been provided for the shipping to safely sail.
