【摘要】 江山港是江山市境内的主要河流。随着社会经济的进一步发展,江山市将开拓江山港两岸的新城区,由此提出新城区防洪规划的要求。首次利用一维非恒定流水动力模拟系统MIKE11建立了江山港这类山溪性河流的水动力模型。在江山港遭遇50年一遇的洪水时,采取水库调洪、河道切滩、河道疏浚工程措施下,利用该水动力模型,计算了新城区沿程洪水位,为江山市新城区防洪规划中的防洪工程设计提供科学依据。更多还原

【Abstract】 Jiangshan river is a major river in Jiangshan area.The new urban area along the banks of Jiangshan river will be developed with the further growing of social economy,for which the flood prevention planning is required.One-dimensional unsteady flow hydrodynamic analogy system is utilized for setting up Jiangshan river hydrodynamic model.Flood level in new area of Jiangshan is computed through the model at flood of 50 years once,which provides scientific basis for designing flood prevention projects.更多还原
