基于无结构、σ坐标网格的半隐式三维水沙数学模型Ⅱ-验证
3-D hydrodynamic model for free-surface flows and sediment transport on unstructured σ-coordinate grid.Part II.Model validation
摘要
Abstract
The model described in part I of this paper is compared with several similar hydrodynamic models,and it is validated through several test cases.Successful simulations of tide flows in natural rivers indicate that this new model can simulate free-surface flows and that it is robust in modeling complex river boundaries.The model was validated by comparing its hydrodynamic and sediment transport predictions with the measured data of a pure erosion experiment,an experiment of local scouring around a spur-bar of trapezoid cross-section and the natural river field data of bed deformation,and good agreements were obtained.关键词
