Virtual Simulation Modeling and Visual Analysis of Sediment Erosion and Deposition Change in River Basin

Abstract:

A method of simulation modeling and virtual presentation of river evolution was proposed. The method used a variable scale modeling method to generate virtual environment and the data model of irregular triangle network to build the river channel. The virtual environment and the river channel are unified with seamless splicing algorithm to enhance the sense of immersion. And then digital river simulation platform was developed. It displayed the erosion and deposition of river channel with color mapping and presented an efficient algorithm to analyze the change of section shape. The proposed method is validated by application in analyzing the sediment deposition and erosion of Chongqing reach of Yangtze River.
