基于动力波法的高效高分辨率城市雨洪过程数值模型
High-performance numerical model for high-resolution urban rainfall-runoff process based on dynamic wave method
摘要
Abstract
Based on the dynamic wave method,a high-performance numerical model for high-resolution urban rainfall-runoffprocess is presented in this paper.This high resolution digital elevation model (DEM) is in the framework ofa Godunov-type finite volume scheme to solve the shallow water equations (SWEs).Aimed at accurate prediction of urban rainfall-runoff and inundation process,it resolves the realistic features of urban terrain and uses a Graphic Processing Units (GPU) parallel computing technique to accelerate calculation.Validation results by modeling the Xixian new area in Shaanxi indicate that our model is reliable and efficient in accurate calculations of all the five inundation spots and gives detailed flow velocities for analysis of the causes of inundation and the pollutant transport process,useful for urban planning and storm water management.关键词
