摘要
Abstract
Based on typical years of measured data,the relationship between the diversion of floods at the Xin Gate and the Wujiang Gate,the flow pattern and velocity distribution on the Xin Gate,and the drop height between the Xin Gate and the Wujiang Gate were analyzed.The reasons for the insufficient backflow and diversion ratio in the upper reaches of the Xin Gate were explored.A hydrodynamic mathematical model coupling hub and river channel was constructed,and the model was validated using cross-sectional velocity distribution and measured diversion comparison.The flow conditions of the current situation and engineering combination conditions were simulated.The results show that the combination scheme of a 6-meter elevation of the left bank cut-off bottom and dredging below the Xin Gate can basically eliminate the adverse flow pattern on the Xin Gate and improve the discharge diversion ratio of the Xin Gate.关键词
