摘要
目的:验证MIKE21模型对椒江口-台州湾常态下泥沙输运应用的适用性。方法:利用MIKE21模型,构建了椒江口-台州湾泥沙输运数值模型,并对研究范围进行网格划分,结合该研究区域地形特征,以2009年4月26日至4月30日椒江口-台州湾实测资料为基础,模拟计算了椒江口-台州湾常态下的泥沙输运演进过程。结果:在研究时间段内潮位、流速流向以及含沙量等参数计算值与实测值符合性较好,河口流路和河道的走向一致,白沙—黄琅一线表现为较为明显的东海域潮流旋转流性质;验证点模拟含沙量量级及其变化趋势与实际情况量级大致相同。结论:率定后的计算模型对椒江口-台州湾模拟具有良好的适用性,可以用于常态下泥沙输运模拟。
Aims:This paper studies the distribution characteristics of sediment transport under the normal status of the Jiaojiang River estuary-Taizhou Bay by using the MIKE21 model.Methods:The numerical model of the Jiaojiang River estuary was constructed by using the MIKE21 model.With meshing division of the studied area accarding to its topographical features,the evolution of the Jiaojiang River estuary-Taizhou bay under normal status was calculated based on the measured data from April 26 to April 30 in 2009.Results:During the study period,the calculated tidal level,sea flow velocity and sediment concentration were in good agreement with the measured values.The estuary flow path and the river course were consistent.The Baisha-Huangqi line was characterized by the relatively obvious tidal current flow in the east sea.Conclusions:The calculation model after verification rate has good applicability to the Jiaojiang River estuary -Taizhou bay simulation,and the sediment is affected by the tidal current.
