Abstract

This study evaluates the sustainability of estuarine reservoir water resources for water use and flood control, considering future environmental changes such as climate and land use changes. Future environmental data were constructed, and a watershed-reservoir linkage model simulated reservoir water resource changes. A sustainability index based on reliability, resiliency, and vulnerability was used to assess the current management plan. The analysis showed that the current plan for Ganwol estuarine reservoir may cause future issues with water use and flood control, with sustainability indices ranging from 0.2 to 1 for water use and 0.65 to 1 for flood control. Water use sustainability was found to be lower than flood control sustainability, due to differences in design frequencies and the reservoir's artificial drainage capacity. An analysis of changes in sustainability from raising the control water level during the non-flood season showed a decrease in water use failures, with the sustainability index increasing by 0.2 to 0.75, improving sustainability. While effective for water use, the plan may reduce flood control sustainability, indicating the need for additional measures. This study provides a quantitative method to assess reservoir management sustainability under future environmental changes.

본 연구에서는 지속가능한 하구 담수호 수자원 관리방안 마련을 위해 기후변화, 토지이용 변화 등의 미래 환경 변화에 따른 하구 담수호 이수 및 치수 지속가능성을 평가하였다. 이를 위해 미래 환경 변화 자료를 구축하고 유역-호소 연계 모형을 이용하여 담수호 수자원 변화를 모의하였다. 또한, 신뢰도, 회복도, 취약도 지표 기반의 수자원 지속가능성 지수를 산정하여 현재 담수호 관리방안의 지속가능성을 정량적으로 평가하였다. 분석 결과, 현재 간월호의 관리수위 운영 방안은 미래에는 이수, 치수 문제를 발생시킬 것으로 분석되었으며, 이수 지속가능성 지수와 치수 지속가능성 지수는 각각 0.2~1, 0.65~1의 범위로 나타났다. 현재 담수호의 관리방안에서는 이수 지속가능성이 치수 지속가능성보다 낮은 것으로 분석되었으며 이는 담수호의 이수, 치수 설계빈도의 차이와 담수호의 인위적 배수가 가능한 특성 때문으로 사료된다. 이에 비홍수기 관리수위 상향 방안에 따른 지속가능성 변화를 분석하였으며 그 결과, 이수 측면에서 실패 발생 횟수가 감소하였으며 이수 지속가능성 지수가 약 0.2에서 0.75로 증가하여 이수 지속가능성이 향상됨을 확인할 수 있었다. 따라서 이 관리방안은 이수 측면에서 효과적인 것으로 나타났다. 그러나 치수 지속가능성이 낮아질 것으로 예상되어 추가적인 치수 측면의 방안 마련이 필요할 것으로 보인다. 본 연구는 미래 환경 변화를 고려하여 담수호 관리방안에 따른 지속가능성을 정량적으로 평가 방법을 제안하였다.
