Abstract
In order to achieve the simulation and preview function for the development process of ice in the digital twin Wanjiazhai Reservoir,multiple geographic spatial data sources,such as BIM models,oblique photography models,and GIS scenes,were integrated to construct a fully digital scene of the Wanjiazhai Reservoir area.Based on the forecast and early warning results of the water-ice dynamic coupling model in the reservoir backwater area,geospatial,meteorological,hydrological,and ice forecast data were coupled with the mathematical model of ice-water dynamics in the reservoir backwater area to simulate the effects of different combination conditions of reservoir water levels,flow rates,incoming ice,terrain,and other conditions on ice accumulation.Through the integration of ice-water dynamics theory and the Unreal Engine+GIS Engine,the data on the ice development process were previewed in the simulation scene.The mapping and representation of 2D simulated data on the ice development process in the digital twin 3D scene were achieved.This study provides high-level information support for the"Four Pre"function of anti-ice dispatching in the Wanjiazhai Reservoir area.关键词
