The Analysis on the Water-Sediment Characteristics and the Influences of Sluice Construction in Jiaojiang River Estuary

According to the field observation data of Jiaojiang River estuary in the dry season of 2013 and the flood season of 2014, the paper has analyzed the variation of water-sediment characteristics among three river sections (Lingjiang River, Jiaojiang River and Jiaojiang River Mouth). Based on the underwater topographic data in recent years, the erosion and deposition evolution of riverbed has been studied. The effect of the relative strength of runoff and tide on the water-sediment characteristics and the riverbed evolution has been discussed according to data analysis. The effect made by sluice construction in the river and estuary has also been discussed employing the result of numerical simulation research made by Nanjing Hydraulic Research Institute.
