영문 초록

Various characteristics of creek were not considered in designing creek for a long time. As result of that, a lot of reverse functions have been present in creek. In this study, a presentation of creek damage was investigated and differences river form creek design standards were analyzed. The damage of creeks accounts for 37.3 percent of total damage of rivers over the last 6 years. Besides, government should spend more money in restoring creeks. Considering that maintenance rate of domestic creeks is 37 %, counterplan should be prepared to prevent the damage of creeks. There are many kinds of causes in destroyed creek round. Specially, most damage was secondary that was caused by increase of flood elevation according to decrease in conveyance, local scour around structures, and failures because of inappropriate structures such as bridge, culvert, crossbeam, and drop in creek. These destroy types are in bend area. However, current creek design standards do not suggest solutions to prevent damages. Currently, there are no standards for bridge, and appropriate hight and width of culvert. Standards for crossbeam and drop could not reflect characteristics of creek. Therefore, it is need to improve the creek design standards for appropriate design and construction. That could improve flood control and prevention of creeks.
