碩士 === 中原大學 === 土木工程研究所 === 90 === Abstract Formosa Taiwan is a place with diverse natural resources, and it also nurtures the creation and supplies the habitats for breeding and feeding in the river region. In order to maintain and create the biodiversity around the water environment, “The Near-Natural Working Method” is gradually considered in harnessing, utilizing and approaching the river region. And the design and plan with near-natural working method at Fa-Tzu River in Tai-Chung area is selected as simulated example. The River Analysis System developed by the Hydrologic Engineering Center（HEC-RAS） in America is performed one-dimensional steady flow hydraulics. Therefore, the high water level analyses those are compared before and after the design in Fa-Tzu River prove the ability of conveyance by the system HEC-RAS. As a result of the initial achievements about the cross section design and high water level analysis, the study aims at offing the suggestions to the application in harnessing the river by the plan with the Near-Natural working method.
