Abstract
Through the analysis of Ningxia reaches of the channel evolution of the Yellow River,it researched on the erosion and scour and river re-gime changes of the river section in Ningxia. The results show that in the period of 1993-2009,in Ningxia section of the Yellow River Xiaheyan to Qingtongxia river channel erosion and deposition of average balance to Qingtongxia to Shizuishan reach of the river is in silting status. Ningxia section of river channel scouring and silting variation depend largely on the conditions of water and sediment,water and sediment and flood in,full of sediment siltation in the river main channel within the main channel siltation shrink,small and medium water level significantly inflated. River in Ningxia section of the Yellow River canyon and pebble river bed scour and less mainstream swing,the rest of river beds scour and mainstream swing are greater. The implementation of river training works on the controlling river regime changes has an effect. Ningxia section of the Yellow River water and sediment conditions,river boundary condition and river bed texture are the causes to influence the channel evolution.关键词
