Abstract

River management based on gray infrastructure under industrialization and urbanization has been effective in the short term but has revealed clear limitations by weakening the intrinsic ecological and geomorphological functions of rivers. In the era of climate crisis, nature-based solutions (NbS) are emerging as an alternative approach to river management; however, research on their real-world applications and effectiveness remains limited. This study investigates the current status of river management practices in South Korea, classifies the cases that correspond to NbS, and analyzes their characteristics. The identified NbS include removal of cross-river structures, construction of detention reservoirs, wetland creation, levee setback, removal of in-channel vegetation, restoration and creation of in-channel wetlands, removal and dredging of floodplains, and maintenance of natural levees, totaling 27 cases. An analysis by river space units shows that management interventions within the river corridor have been relatively active, whereas improvements outside the channel or along levees have been comparatively limited. Although modifications to levees and the floodplains involve complex stakeholder interests and high costs, they are evaluated more positively because they can enhance river resilience. For sustainable river management in the future, it is necessary to empirically verify the effectiveness of NbS and develop policies that strengthen resilience over the long term.

산업화와 도시화에 따른 그레이 인프라 기반의 하천 관리는 단기적으로는 효과적이지만, 하천 고유의 생태·지형적 기능을 약화시키는 한계를 드러내고 있다. 기후위기 시대에서 자연기반해법(Nature-based Solutions, NbS)은 하천 관리의 대안으로 대두되고 있으나, 실제 적용 사례와 그 효과에 대한 연구는 부족하다. 본 연구는 국내 하천에 적용된 하천 정비 현황을 조사하고, 자연기반해법 사례를 유형화하여 그 특징을 분석하였다. 적용된 자연기반해법은 횡단구조물 제거, 저류지 조성, 습지 조성, 제방 이설, 하도 내 식생 제거, 하도 습지 복원 및 조성, 둔치 제거 및 준설, 자연 제방 보전 등으로, 총 27건의 사례가 확인되었다. 하천 공간 단위별로 유형을 구분하여 분석한 결과, 하천 내부에 대한 관리는 비교적 활발하게 이루어졌으나, 하천 외부나 제방에 대한 개선은 상대적으로 부진한 것으로 나타났다. 제방 및 제내지의 변경은 이해관계가 복잡하고 비용이 많이 소요되지만, 하천의 회복력을 증진시킨다는 점에서 보다 긍정적으로 평가된다. 향후 지속가능한 하천 관리를 위해서는 자연기반해법의 효과를 실증적으로 검증할 필요가 있으며, 장기적인 관점에서 회복탄력성을 높이는 정책 마련이 요구된다.
