修水干流水位流量变化趋势分析 Variation Trend Analysis of Water Stage and Discharge in Xiu River

Abstract

通过分析研究修水水位流量关系变化，查找造成水位流量关系发生变化的客观原因，探讨其变化规律，为科学治水、科学决策、科学防灾减灾、科学抢险提供依据。采用修河干流代表站的系列水文资料，对典型站断面冲淤、水位流量变化进行分析，统计不同水文站断面冲淤、水位流量变化，得出修河干流的水位流量变化规律。结果表明；修河干流受河道采砂影响，水位~流量关系不稳定。 Through analyzing the variation of water stage and discharge at Xiu River, variable reasons and rules were explored, which provides certain scientific basis for water conservancy, decision making, disaster prevention, disaster reduction and emergency rescue. The hydrological data series at main stream representative station of Xiu River were used to analyze the section scouring and silting and the change of water level and river flow. The change rules of the water level and river flow in Xiu River was obtained. The result shows that being affected to sand extraction, the water level and river flow in Xiu River main stream are unstable.
