Wei River Channel Evolution Law And Regulation Measures

In recent years, the mainstream of the Wei River runoff sediment and boundary conditions characteristics of some new changes.River plane river regime, a longitudinal section and cross section features Wei River under the new conditions and river water and sediment boundary conditions have emerged some new evolution trend.At the same time, in order to ensure the safety of people and property Wei River to protect the healthy and rapid development of the local and regional economy,but also it requires a combination of the existence of evolution and current status of the issue to take the necessary control measures.Therefore, the impact of the relationship between water and sediment studies and boundary conditions and river evolution and profile features between the Wei River appears to be more urgent.Scope of this study is the Wei River River(Qi door ~ Xu Wancang).First, the measured data of the Wei River River hydrology and sediment characteristics, river characteristics are described.Secondly, never water to sediment conditions of various factors, river morphology, river sediment transport, river erosion and other studies Fluvial, focuses on the impact of runoff and sediment conditions on the riverbed evolution.Finally, some problems Wei River situation, from flood control and drainage, improve flood control planning, promotion of regional economic development in three angles, analysts believe that should be the comprehensive management of the river.Meanwhile, the basic principles of the basic laws of sediment movement and fluvial as a guide, according to channel characteristics and engineering status quo, the use of engineering experience and theory, put forward some control measures as well as analysis and comparison of the recommendations of a special river regulation measures.Work of this paper to explore the basic law for the full South Canal riverbed erosion and deposition evolution;Analysis of trends that may arise under the current river water and sediment conditions development trend and profile, cross-section;For the analysis of other similar natural geographical conditions of river evolution;Study river training works measures to promote stability in the direction of the river to have a certain theoretical value and practical significance.
