| 摘 要： | 从河口近岸悬沙浓度的影响因素入手,在收集现场实测资料的基础上,对悬沙浓度的变化规律进行分析。通过分析研究,建立了悬沙浓度变化与多因子响应高精度三维数值模型。以黄茅海水域1992年11月15日—19日实测水流、泥沙、风等资料为基础,对模型进行验证。结果表明:模型能较好地模拟河口水流泥沙运动,且计算稳定性好、精度较高。水流、泥沙运动验证成果基本能达到规范要求的精度。

| Abstract: | From the influential factors of the estuarine and coastal suspended sediment concentration,and based on the field data,the author analyzes the change laws of suspended sediment concentration and establish a three-dimensional high-precision numerical model of suspended sediment concentration change and multi-factor response.On the basis of the measured flow,sediment and wind data of Huangmao waters in Nov.15-19,1992,the author verifies the model.The results show that the model can simulate the flow and sediment movement with stable calculation and high precision.The verified results of flow and sediment movement can basically meet the requirements of precision. |
