摘要
洪水演进分析是洪水调度的重要基础。针对梯级开发河流洪水演进数值模拟方法、糙率n的率定方法、数字高程建模以及洪水调度理论方法等研究进展进行了综述,指出基于高精度数字地形的一二维耦合水动力模型研究对于梯级开发河流洪水演进分析及防洪优化调度具有重要意义;无人机倾斜摄影测量、无人船水下断面测量等先进测量手段在获取高精度数字地形方面具有很大的应用潜力。
Flood evolution analysis is an important basis of flood control.The research progress of numerical simulation method,calibration method of roughness n,digital elevation modeling and flood regulation theory of cascade development river is reviewed.It is pointed out that the research of one-dimensional coupled hydrodynamic model based on high-precision digital terrain is of great significance for flood evolution analysis and flood control optimal regulation of cascade development river;and the advanced measurement methods such as UAV tilt photogrammetry and underwater cross-section measurement of unmanned vessel have great application potential in obtaining high-precision digital terrain.
