초록

우리나라를 포함한 여러 나라에서 도시화와 이상기후로 인해 홍수 예측이 어려워지고 있다. 이러한 점에서 유역의 토지이용, 인간의 활동, 수문 시스템의 상호작용을 고려한 사회수문학 연구가 제안되고 있다. 그러나 현재 사회-수문 시스템의 동적 상호작용과 관련한 피드백에 대한 이해는 전반적으로 부족한 상황이다. 본 연구에서는 시스템 동역학적 모형을 이용하여 제내지에서 인간의 활동, 제내지에서 거주지 확장 및 쇠퇴 등 사회수문학적 관점에서 인문 시스템과 수문 시스템 사이 상호작용을 검토하였다. 즉, 동적 변화에 미치는 영향을 고려한 홍수 측면에서 개념화 모형을 제시하고자 한다. 양재천을 대상으로 제방에 투자되는 비용에 따라 세 가지 시나리오를 고려하여 홍수위험도와 사회수문학적 시스템의 상호작용을 모의하였다. 사회수문학적 상호작용을 통해 양재천 변화양상을 모의해본 결과 과거의 변화양상을 효과적으로 모의할 수 있었다. 기후변화 등 미래의 발생 가능한 수문기상학적 변동성과 사회시스템과의 상호작용을 전망하고 의사결정의 보조 수단으로 활용이 가능할 것으로 판단된다.

In many countries, including Korea, it has been challenging to understand flood-related social dynamics due to urbanization and climate change. In this regard, socio-hydrology has been proposed to consider the interaction between hydrologic systems, land-use change, and human activities. However, there is a general lack of understanding of the interactions of socio-hydrologicsystems. This study examines the interactions between human activities and hydrologic systems from a sociological perspective using a dynamic system model. In other words, this study aims to present a conceptualization model that considers the mutual interaction of flood and community from a socio-hydrologic perspective. Depending on the construction cost of the levee for the Yangjae River, this study considered three scenarios to simulate the interaction of socio-hydrologic systems. Socio-hydrologic interactions can effectively reproduce the changes in the Yangjae River. Moreover, It is expected that the proposed model can be further used to understand possible hydrologic changes and interaction with social systems in the future as a decision-making tool in water resources management.
