Abstract

In addition to structural stabilization measures such as the construction of Sand Dam, non-structural management measures such as reasonable water demand and supply volume management are needed to prevent limited water supply damage due to drought. In this study, water supply-demand monitoring system was established for drought response in Seosang-ri basin in Chuncheon, the main source of domestic water for small water facilities. The flow rate of the stream was measured for monitoring the supply volume, and the daily flow rate was calculated by using it to calibrate the parameters of the SWAT (Soil and Water Assessment Tool). To monitor demand, the daily usage was calculated by measuring the change in the water level of the water tank. The relationship between the finally calculated daily supply and demand amount was analyzed to identify the shortage of water.

가뭄으로 인한 제한급수나 단수로 인해 발생할 수 있는 물 복지 소외지역의 불편과 경제적 피해를 예방하기 위해서는 Sand Dam 건설과 같은 구조적 안정화 방안과 더불어 합리적 수요/공급량 관리 등을 통한 비구조적 관리 대책이 필요하다. 본 연구에서는 소규모수도시설이 생활용수의 주 공급원인 춘천시 서상리 유역의 가뭄대응을 위해 공급량-수요량 모니터링 체계를 구축하였다. 공급량 모니터링을 위해 상류부 하천의 유량을 측정하였으며, 이를 SWAT (Soil and Water Assessment Tool)의 매개변수 보정에 사용하여 일별 유출량을 산정하였다. 수요량 모니터링을 위하여 하천-저수조-가정으로 이어지는 용수 공급 네트워크를 작성하였으며, 저수조의 수위 변화를 측정하여 일별 사용량을 산정하였다. 최종적으로 산정된 일별 공급량과 수요량 간의 관계분석을 통해 용수 부족 여부를 파악할 수 있었으며, 가뭄 대응을 위한 효과적인 지표로 사용될 수 있을 것으로 판단된다.
