详细测试了一个新的二维水力模型系统。该方法包括应用水力模型的一组理论测试，其中的解析解是已知的，然后比较模型模拟与真实的洪水事件。静止水测试、三次溃坝测试和Seiche测试构成了一组具有解析解的测试。洪水事件是博斯卡斯尔2004年洪水，可获得观测水位。该模型产生的结果，比较密切的分析解决方案，在所有的测试，除了假潮测试。当应用于真实的洪水事件时，模拟的最高水位接近于观测水位。与两个类似的商业软件包的比较显示出相似的结果之间的模型。
Detailed testing of a new two‐dimensional hydraulic modelling system is presented. The methodology consists of applying the hydraulic model to a set of theoretical tests, for which analytical solutions are known, and then comparing a model simulation with a real flood event. The water‐at‐rest test, three dam‐break tests and the Seiche test constitute the set of tests with analytic solutions. The flood event is the Boscastle 2004 flood, for which observed water levels are available. The model yields results that compare closely with the analytical solutions in all of the tests, except for the Seiche test. When applied to the real flood event, the simulated maximum levels are close to the observed levels. Comparisons with two similar commercial software packages show similar results between the models.
