Abstract

Efficient management and analysis of river data are essential for flood prevention, river design, and water resource management, necessitating technological advancements to overcome the limitations of conventional data management systems. This study proposes an integrated river data management system utilizing the ArcDas platform and Web-GIS technology to systematically manage various structured and unstructured data sources, including river master plan data, CAD data, drone imagery, and sensor data. The proposed system was applied to two study areas, the Geum River-Miho Stream confluence and the Nakdong River-Nam River confluence, to verify its effectiveness. In particular, this study developed a data processing method to automatically extract cross-section data from CAD files of the river master plan and convert it into HEC-RAS input files (Geometry), significantly reducing data processing time compared to manual methods. The results indicate that the proposed system enhances data processing efficiency by automating CAD-to-HEC-RAS data conversion and integration, while also maximizing the usability of river environment analysis through real-time data visualization using Web-GIS. Furthermore, by transitioning from point-based data management to a continuous cross-section-based data management system, the study confirmed that data consistency and usability were significantly improved compared to conventional point-based management methods. This research presents a new paradigm for integrated river data management and analysis, addressing inefficiencies in Korea’s current river management system and strengthening data-driven decision-making support.

국내 하천 데이터의 효율적 관리와 분석은 홍수 예방, 하천 설계 및 수자원 관리의 필수 요소로서, 기존 데이터 관리 체계의 한계를 극복하기 위한 기술적 개선이 요구된다. 본 연구에서는 ArcDas 플랫폼과 Web-GIS 기술을 활용하여 하천기본계획 자료, CAD 데이터, 드론 영상, 센서 데이터 등 다양한 정형 및 비정형 데이터를 통합적으로 관리할 수 있는 시스템을 구축하고, 이를 연구 대상 지역에 적용하여 실효성을 검증하였다. 특히, 하천기본계획 CAD 자료를 활용하여 하천 단면을 자동 추출하고, 이를 HEC-RAS 입력 파일(Geometry)로 자동 변환하는 데이터 처리 과정을 개발함으로써 기존의 수작업 방식 대비 데이터 처리 속도를 크게 단축하였다. 연구 결과, 하천기본계획 자료를 기반으로 CAD 데이터를 자동 변환하고, HEC-RAS와 연계하는 과정에서 데이터 처리의 효율성이 향상되었으며, Web-GIS를 활용한 실시간 데이터 시각화를 통해 하천 환경 분석의 활용성을 극대화하였다. 또한, 기존의 점 단위 데이터 관리 방식에서 벗어나 단면 단위의 연속적인 데이터 관리 체계를 구축함으로써, 기존의 점 기반 방식 대비 데이터의 일관성과 활용성이 증대되었음을 확인하였다. 본 연구는 하천 데이터의 통합 관리 및 분석 체계를 제안함으로써, 국내 하천 관리 시스템의 비효율성을 극복하고, 데이터 기반의 의사결정 지원을 강화할 수 있는 새로운 패러다임을 제시하였다.
