一、实验目的江西省赣、抚、信、饶、修五大河流每年汛期挟带大量泥沙至五河尾闾并汇入波阳湖中。悬移质泥沙大部份沉积到波阳湖湖盆之中或排往长江,影响不大。而推移质泥沙则由于五河尾闾坡降平缓,流速较小,逐渐沉积在河道弯段的凸岸,扩散段,桥墩旁及入湖三角洲等处。不但影响了下游河道的通航能力,而且对堤防的加高加固工程量及排渍闸或工业供水工程的取水口(淤塞)带来不利影响。为搞好波阳湖商品粮基地的水利规划,治理好我国目前最大的淡水湖-波阳湖,江西省科委将泥沙淤积问题作为一项重点科研项目下达。鉴于推移
First, the purpose of the experiment Jiangxi Province, Fu, letter, Rao, repair the five major rivers every year flood season with a large amount of sediment to five river tail and remitted to the Bo Yang Lake. Sediment sediment deposition most of the sediments to the basin or to the Yangtze River, little effect. The sediment transport is due to the gentle slope of the Lower Wuluo gentle slope, the flow rate is relatively small, and gradually deposited in the curved bend of the bank, the diffuser, piers and into the lake delta. Which not only affected the navigable capacity of the lower reaches of the river but also adversely affected the amount of reinforcement and reinforcement of dikes and the water intake (blockage) of sluice gates or industrial water supply projects. In order to improve the water conservancy planning of the commodity grain base in Bo Yang Lake and manage the largest freshwater lake in China - Bo Yang Lake, Jiangxi Provincial Science and Technology Commission will issue the sediment deposition as a key scientific research project.
