摘要
河道的冲淤变化主要取决于来水来沙条件、河床边界条件以及河道采砂等人类活动影响,其中来水来沙是河道冲淤的决定因素。本文从赣江下游控制水文站外洲站的水文观测资料统计分析入手,结合采砂、修建水库等人类活动影响的分析,采用趋势分析法对赣江下游水沙过程进行分析,并对赣江未来水沙变化趋势进行预测。
The erosion and sedimentation of the river course mainly depend on the influence of human activities such as incoming water and sediment conditions,river bed boundary conditions,and river sand mining,among them,in?coming water and sand are the determinants of river erosion.This paper started with the statistical analysis of the hy?drological observation data of the Waizhou station controlling the hydrological station in the lower reaches of the Gan?jiang River,and combined the effects of human activities such as sand mining and reservoir construction,and used the trend analysis method to analyze the water and sediment process in the lower Ganjiang River,and forecasted the future runoff and sediment change trend of Ganjiang River.
