Evaluation of the Effects of Channel Regulation Engineering Works in Typical Braided Reach

Abstract:

The evaluation of the effects of regulation engineering in Jiayu-Yanziwo reach is presented through the process of: (a) the introduction of study area and regulation works; (b) the establishment of a two-dimensional flow and sediment numerical model; (c) the evaluation of regulation works effects. According to the phenomenon of river process, a series of engineering to prevent the sand bar from erosion are designed. The effects of prevent works is simulated by 2D numerical model verified with measured data. After impound of the prevent engineering, the min navigation width while depth is 3.7m is greater than 150m, the good navigation conditions will maintained in next decade.
