综合生物力学流动模型的最新发展,使预测植被对流场和相关的反馈过程的影响。然而,到目前为止,这种模型仅在水力预测和/或平均电厂位置上得到验证。在这里,我们介绍了一种方法,其中使用在水槽实验中直接测量的动态替代植物运动来实现能够评估数值模型内与时间相关的水流-植被相互作用的准确性的验证方法。我们使用这种方法来证明现有的欧拉-伯努利梁模型的准确性,通过时间和空间预测的平均和动态的植物位置。
Recent developments in integrated biomechanical-flow models have enabled the prediction of the influence of vegetation on the flow field and associated feedback processes. However, to date, such models have only been validated on the hydraulic predictions and/or mean plant position. Here we introduce an approach where dynamic surrogate plant motion, measured directly in flume experiments, is used to allow a validation approach capable of assessing the accuracy of time-dependent flow–vegetation interaction within a numerical model. We use this method to demonstrate the accuracy of an existing Euler–Bernoulli beam model in predicting both mean and dynamic plant position through time and space.
