Abstract

Detail 3D digital elevation model with a high-accuracy efficient software for 2D-modeling STREAM 2D CUDA and actual data on high-water marks and the dynamics of water level variations during a flood in 2019 on the Iya R. near Tulun Town were used to evaluate the maximal water flow rate and to plot the hydrograph of extreme flood near Tulun Town. The calculated complex dynamics of the inundation of the town located in a diked river bend showed a good agreement with observation data.

2019 年洪水期间 Iya R. Tulun 镇淹没的数值流体动力学 2D 模拟

摘要

详细的 3D 数字高程模型，采用高精度高效的二维建模软件 STREAM 2D CUDA 和高水位线的实际数据以及图伦镇附近 Iya R. 2019 年洪水期间水位变化的动态评估最大水流量并绘制图伦镇附近极端洪水的水位线。位于堤坝河弯处的城镇淹没的计算复杂动态与观测数据非常吻合。
