Sameh A. Kantoush 교수의 연구실은 주로 수자원 시스템의 지속 가능성과 퇴적물 관리에 초점을 맞추고 있습니다. 특히 댐과 저류지의 퇴적물 축적 문제를 해소하기 위해 유량 제어, 흐름 패턴 분석, 물리적 및 수치 실험을 통한 퇴적 및 제거 메커니즘 연구를 수행합니다. 아시아와 유럽의 다양한 강유역(메콩강, 알프스 강 등)을 대상으로 한 사례 기반 연구를 통해 퇴적물 관리 전략과 수자원 보존 기술을 개발하고 있습니다. 특히, 수문학적 복원과 퇴적물 봉쇄 방지 기술의 통합적 접근이 핵심입니다.

ヨーロッパアルプス地域のダム貯水池は，流入河川がもたらす土砂の堆積作用によって，その持続可能性が著しく脅かされている。このような貯水池に対する土砂管理計画を，一般化された基準や方策で記述することはなかなか難しい。本報では，日本とアルプス地域のダムにおける土砂堆積に伴うリスクを定義し，これを適切に計測することを目的としている。特に，総合土砂管理の導入によって，水資源の持続的利用，生物環境の保全，さらには，人間と自然の調和を図るために，健全な河川流域を如何に維持するかが最終的な目的である。土砂管理を成功させるためには，河川マネジメントから根本的に変える必要があり，これには，いくつかの対策の組み合わせにより，ダムを通過する水量と土砂量をバランスさせることが重要である。アルプスの大規模貯水池では，密度流が細粒土砂を高濃度で輸送する現象がしばしば観察され，これを適切に制御することが求められる。
Between 2015 and 2016, Vietnamese Mekong Delta (VMD) has undergone the most severe drought event over the last 90 years, causing damages to agriculture, aquaculture, and fresh water suply. Moreover, upstream Mekong River development by constructing hydropower dams will magnify the severity to the region. This research therefore aims at summarizing some damaged information caused by drought event 2015-2016 and analyzing the impacts of eleven proposed mainstream dams in Thailand, Lao PDR, and Camb
The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by the reservoir geometry. The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the
Depositional and flow patterns are first described to gain an understanding of the erosion patterns during hydraulic flushing in a reservoir. Considering the importance of this issue, two modes of flushing operation for control of sedimentation were performed in several experiments with different reservoir geometries. In order to investigate the effect of flushing and the effectiveness during free and drawdown flows, ten experiments have been conducted. The final bed morphology formed previously
This paper evaluates the performance of the sediment bypass tunnel that diverts the suspended sediment from Lake Miwa to downstream reaches below Miwa dam. In such a complex processes during bypassing, it is difficult to predict the sediment bypassed efficiency numerically. Therefore, the digital image techniques were developed and implemented to measure the flow pattern and suspended sediment concentration SSC for the first time in Miwa dam. Where, field measurements were conducted during flood
