甘溪港滩位于洞庭湖汊流甘溪港河与资水尾闾汇合处,是湖南省长(沙)津(市)、长益(阳市)、益茅(草街)常年干线航道的咽喉,治理好本滩,对发挥湖南“北水”的水运优势具有重要的作用。但从1954年以来对该滩几经治理,由于河型复杂、水流紊乱、泥沙运动频繁,一直未能得到根治,每年均赖挖泥,才能维持1.3～1.5×20×100～150米的单线航道尺度。为早日实现“北水”开发方案,必须对甘溪港滩的河床演变及工程措施作进一步的研究。
Ganxi Port is located at the confluence of Gansu Port and Ganshui Port, the capital of Dongting Lake. It is the throat of the governors of Hunan Province (Sha) Tianjin (City), Changyi (Yangshi) and Yimao (Caojie) , Good management of the beach, to play the “north water” of Hunan water transport has an important role. However, since 1954, due to the complicated management of the beach, the river has been in disorder and the flow of water has been disturbed and the sediment movement has been frequent. It has not been eradicated and dredged every year to maintain a single line of 1.3 to 1.5 × 20 × 100 to 150 meters Waterway scale. In order to realize “North Water” development project as soon as possible, further study on riverbed evolution and engineering measures in Ganxi Harbor must be conducted.
