建立了河漫滩环境下深度平均自由表面流动的二维有限元模型原型。对模型的物理表示进行了有限的改进，并将增强方案应用于英国11公里的河道/河漫滩河段。模型初步结果表明，这种建模方法可用于识别10-100米长度尺度上流场参数的动态变化。潜在地，这些数据有能力对冲积平原的短期沉积动力学进行详细分析。
A prototype two-dimensional finite element flow model for depth-averaged free surface flows was developed for floodplain environments. Limited refinement of the model's physical representation was undertaken and the enhanced scheme applied to an 11 km river channel/floodplain reach in the U.K. Preliminary model results indicate that this modelling approach can be used to identify dynamic variations in the flow field parameters over length scales of the order of 10-100 m. Potentially, such data have the ability to permit detailed analysis of short-term floodplain sedimentary dynamics.
