TL;DR: In this article, the authors developed an optimal river dredging management model by applying MCDA (Multi-Criteria Decision Analysis) technique specifically in Korea where river diversification research are scarce.

TL;DR: In this paper, the long-term riverbed-level variation of Geum river basin due to water gate operation of multi-functional weirs was studied and the results showed that the variation of thalweg elevation was greater than the average riverbed elevation.

Abstract: The river environment in Korea has changed significantly after the completion of the Four Major Rivers Project due to the outdated river management methods and thus, it is necessary to modify the current river management process. A typical example of this management is dredging but it is a method that usually results in socio-environmental side effects. Therefore, in order to minimize the socio-environmental impacts of dredging, Korea is currently applying the Environmental Windows, a management practice currently being used in the United States that eliminates the risk of potentially harmful impacts of dredging. The use of statistical methods was suggested to address the issue of 낙동강 유역의 친환경 하천 준설을 위한 환경창 수립 방안* 정안철1)⋅김성원1)⋅김민석2)⋅정관수1)** Environmental Windows Setting Method for Environmental-Friendly River Dredging in Nakdong River Basin* Anchul Jeong1)⋅Seongwon Kim1)⋅Minseok Kim2)⋅Kwansue Jung** 1) 충남대학교 토목공학과(Department of Civil Engineering, Chungnam National University) 2) 충남대학교 국제수자원연구소(International Water Resources Research Institute, Chungnam National University) 제출: 2015년 8월 31일 수정 : 2015년 11월 26일 승인 : 2015년 12월 23일 * 본 연구는 국토교통부 물관리연구사업의 연구비지원(11기술혁신 C06)에 의해 수행되었습니다. ** 교신저자: ksjung@cnu.ac.kr

TL;DR: In this article, the authors established environmental windows for estimation of environmental friendly dredging season considering legal protected species and main fish type at 16 multi-functional weirs in the domestic.

TL;DR: In this article, the efficiency of sediment sluicing by various operation at water surface elevation on multi-functional weirs were analyzed using Nays2DH, and focused on the Dalsung weir at Nakdong river.
