Abstract
Abstract At the bends of a river, the deflected flow of high energy erodes the embankment and transports sediment,ultimately changing the river’s course. Such phenomena lead to instability of the embankment and may cause seriousproblems for nearby roads, land, or riverside structures. This study intends to analyze the characteristics of hydraulicflow at S-shaped bends after the installation of Riprap Weirs designed to prevent changes in a river’s course and embankment erosion. An experimental channel was constructed by a two-dimensional CCHE2D model, and analyzedthe characteristics of hydraulic flow with and without the Riprap Weirs. Also, the characteristics of hydraulic flowat the inner and outer sides of river bends and at points near reservoirs were analyzed , depending on the intervalsbetween the Riprap Weirs. Key Words : CCHE2D Model, Meandering Channel, Riprap Weir 이 논문은 2012년도 상지대학교 교내 연구비 지원에 의한 것이며, 국토해양부 건설기술혁신사업의 연구비지원(11기술혁신C06)에 의해 수행되었습니다. * Corresponding Author : Sang-Ho Kim(Sangji Univ.)Tel: +82-33-730-0476 email: kimsh@sangji.ac.krReceived January 12, 2015 Revised (1st February 6, 2015, 2nd February 11, 2015) Accepted February 12, 2015
