摘要
针对海河口水沙输移及边界特点,建立了海河口平面二维潮流水沙数学模型.采用1995年10月5～6日小潮及11～12日大潮的实测资料对模型进行系统验证,结果表明,模型计算的潮流流速和含沙过程与实测资料较接近,涨潮、落潮流场与流场变化过程也较符合实际.该模型可为海河防洪排涝与河口治理开发研究提供技术手段.
Based on the characteristics of transportation of flow and sediment in Hal River, and according to boundary condition of the estuary, a 2-D numerical tide model was built. Using the field data of neaps within the dates 5-6 Oct. and spring tide within the dates 11- 12, October, 1995, the model was systemically validated. The result shows that the calculated the tide velocity and the predicted course of sediment concentration are closely fitted with the field data . The prediction of flow pattern and its variations during the course of flood tides and ebb tides are also in agreement with the observed course. The model can provide a valid method to the guideline of Hal River estuary regulation and the flood control.
