This work presents a software platform to compute depth-integrated non-hydrostatic coastal and open channel flows. The software is based on the Vertically-Averaged and Moment (VAM) equations model. The VAM model uses the weighted residual method to account for the non-hydrostaticity and non-uniformity of flow. After presenting the governing equations, numerical scheme and structure of the graphical user interface, the software is applied to solve coastal and open channel flow tests with significant non-hydrostaticity and non-uniformity of flow. The results are compared with hydrostatic model computations and laboratory measurements. Where a hydrostatic-based simulation poorly reproduces experimental observations, the higher-order model equations by this software platform generate excellent predictions. These findings highlight the potential of this user-friendly software platform for modeling open channel, river and nearshore flows and processes, where non-hydrostatic pressure and non-uniform velocity shall be accounted for, which entails a meaningful advance for the hydraulic community.

这项工作提出了一个软件平台，用于计算深度综合的非静压沿海和明渠流量。该软件是基于V ertically-一个veraged和中号矩（VAM）方程模型。VAM模型使用加权残差法解决流量的非流体静力学和非均匀性问题。在给出了图形用户界面的控制方程式，数值方案和结构后，该软件被用于解决具有明显的非静水力和非均匀性的沿海和明渠流量试验。将结果与静水模型计算和实验室测量结果进行比较。在基于静水压力的模拟无法很好地再现实验观察结果的情况下，该软件平台的高阶模型方程可产生出色的预测。这些发现凸显了这种用户友好型软件平台在模拟明渠，河流和近岸水流和过程，
