碩士 === 中華大學 === 土木工程學系碩士班 === 93 === The study on the relationship between meandering properties and failure locations of levee is a purpose of this thesis. The disasters by the flood in July, 2004 in Han-Kei River were surveyed. It was found that the flood discharge was larger than design high water discharge Q100. And the maximum erosion depth Ds were 1.04m~2.51m. Hence, many failures of levee occurred during flood. The failures of levee tend to occur near at bridge. The failures of levee located at -21。<B<19。、-0.31<L/R<0.33. Where the symbol B is an angle measured from the peak of meandering to the failure location and L is a length measured from the peak of meandering to the failure location. The symbol R is a radius of meandering
