Selection and comparison of formulas for flow sediment-laden capacity in water zone of Nanhui East Shoal in Yangtze River Estuary
摘要
Abstract
The water zone of Nanhui East Shoal in Shanghai City is sited at the intersection of Yangtze River Estuary and Hang-zhou Bay. Influenced by comprehensive factors of runoff, tide flow and wave etc. , the calculation for flow sediment-laden ca-pacity in the water zone is complicated. In order to determine the flow sediment-laden capacity formula suitable for the water zone, we analyze and compare the common-used flow sediment-laden capacity formulas for estuary area and select the statisti-cal fitting method, Zhangruijin Formula and Dengjiaquan Formula for flow sediment-laden capacity to carry out analysis-fitting and verification of the suitability of the formulas in different tide periods by the measured data in the water zone. The analysis and verification result shows that Dengjiaquan Formula is more suitable for calculation of flow sediment-laden capacity in the water zone of Nanhui East Shoal.关键词
