分洪区数字地形模型建立及其应用

DEVELOPMENT AND APPLICATION OF DIGITAL TOPOGRAPHICAL MODEL OF FLOOD DIVERSION ZONE

从实用的角度介绍了建立分洪区数字地形模型（DTM）方法，并给出了在分洪区信息可视化、分洪区特征曲线生成、分洪区二维洪水演进等方面的应用。

This paper introduces a practical way to establish Digital TopographicalModel (DTM) of flood diversion zone and its application in visualization of flood diversion zone information, generation of characteristic curves from DTM and 2 dimensionalflood routing in flood diversion zone.
