摘要

基于数字高程模型的栅格结构

以渭河下游洪水淹没数据为基础

依据无源淹没和有源淹没的原理

并结合ERDAS8.5的虚拟GIS模块实现了无源淹没的三维可视化模拟。初步演示了洪水泛滥时的动态淹没过程

促使相关部门高度重视治洪工作。并给政府制定防洪、治洪措施提供了理论依据

从而为进一步开展治洪工作开拓了更广阔的前景。

Abstract

Based on grid of DEM

we take the lower reaches of Weihe flood data as a basis

and combined with Virtual GIS module of ERDAS 8.5

to realize visualized simulation in 3D of nonfountainhead flood according to principle of fountainhead and non2fountainhead.We demonstrate elementary dynamic submerge course of flooding

so as to impel the departments concerned to attached great importances to flood control

and to provide academic foundation for governmental planning measure

therefore to exploit wider prospect for developing governing flood work further.
