MIKE21水动力学模型是研究地表水流运动的可靠手段和重要依据,模型关于平面二维水流的模拟,对于实际水情验证、水文变化计算、未来趋势预测具有重要意义。目前,已有许多专家学者对此展开了多角度、多层次、不同领域的实际应用,并对MIKE21模型的精确度和拟合度进行了反复验证。本文主要综述MIKE21水动力学模型在河道行洪分析、蓄洪区洪水演进、城市内涝风险分析和水利工程建设影响等方面的具体应用,讨论模型在不同模拟条件下得到的水文变化、一般结论以及应用局限性。在此基础上进行阐述和概括,并对MIKE21水动力学模型的应用和发展趋势进行展望。

MIKE21 model is a reliable means and an important basis for studying the movement of surface water flow. The model simulation of planar two-dimensional water flow is of great significance for the actual water condition verification, hydrological change calculation and future trend prediction. At present, many experts and scholars have carried out practical application of multi-angle, multi-level and different fields, and have repeatedly verified the accuracy and fit of the MIKE21 model. This paper mainly reviews the application of MIKE21 hydrodynamic model in river flood analysis, flood evolution in flood storage area, analysis of urban waterlogging risk and impact of water conservancy construction. The hydrological changes, general conclusions and application limitations, which are obtained, are discussed by the model under different simulation conditions. On this basis, it elaborates and summarizes, and forecasts the application and development trend of MIKE21 hydrodynamic model.
