1.
To analyze the feature of dam-break flow in natural channel bends,channel-fitted orthogonal curvilinear coordinate system is established and two-dimensional shallow water equations are derived in this system through coordinate transformation,simplification and depth integration.
为分析溃坝波在天然弯曲河道中传播的特点,建立了跟踪河道走向的正交曲线坐标系,并通过坐标变换、简化和水深积分推导出了曲线坐标系下的二维浅水方程。
6) channel bends

1.
A finite element, method was adopted for weighted convergent mass establishing 2-D flow mathematical model in flow simulation of channel bends, by which the flow pattern of middle and lower channel bends of Li River in the discharge of water transportation was simulated and the calculated results of which concerning water level, flow velocity and discharge were coincident well with measured data.
在弯曲河道的水流计算模拟中 ,用加权的质量集中有限元方法 ,建立了二维弯曲河道水流数学模型 ,模似了黎河中下游弯曲河段在输水流量下的流动形态 ,与实测水位、流速、流量资料相比完全吻合 ,提出弯曲河道护岸在水动力作用下的受力分析方法。
