Abstract

Sand dams are receiving renewed attention as a sustainable water resource infrastructure solution in arid and semi-arid regions. In this study, we comprehensively reviewed the development of sand dam construction technology by comparing and analyzing the traditional Kenyan-type sand dam, the Korean-type bypass multi-stage sand dam (BMSD), and the hybrid system linking the underground dam. In particular, it is very encouraging that the structure is evolving from a structure that simply retains floodwaters to a hybrid water management platform that increases the retention function by raising the water level through the underground dam, following the method of collecting the flow through the riverbed. Accordingly, we compared and analyzed three types of sand dams from the perspective of structural design, hydrological performance, and operation strategy, and also suggested a plan to strengthen the resilience of sand dams in response to climate change. In conclusion, sand dams are expected to be a highly efficient water management strategy technology that actively responds to climate crises in water-vulnerable regions.

샌드댐은 건조 및 반건조 지역에서 지속가능한 수자원 인프라 솔루션으로 새롭게 주목받고 있다. 본 연구에서는 전통적인 케냐형 샌드댐, 한국형 우회형 다단 샌드댐(BMSD), 지하댐을 연계한 하이브리드 시스템을 비교 분석하여 샌드댐 건설 기술의 발전 과정을 종합적으로 검토하였다. 특히 홍수류를 단순 저류하는 구조물에서 하상을 통한 흐름을 모으는 방식에 이어 지하댐을 통한 수위상승으로 저류기능을 높이는 하이브리형 물관리 플랫폼으로 진화하고 있는 것은 매우 고무적이다. 이에 구조 설계적 관점, 수문학적 성능, 운영 전략에서 세 가지 방식의 샌드댐을 비교 분석하고 기후변화에 대응하는 샌드댐의 복원력을 강화하기 위한 방안도 제시하였다. 결론적으로 샌드댐은 물공급 취약지역에서 기후위기에 능동적으로 대응하는 고효율 물관리 전략 기술이 될 것으로 전망된다.
