초록

TMDL에서 효율적이고 체계적인 수질관리를 위하여 하천 네트워크 공간자료 구축 및 이를 이용한 GIS기반의 수질모델링, 자료관리, 공간분석 등이 요구된다. 본 연구에서는 국내 하천 네트워크에 관한 프레임워크 데이터로서 TMDL 실무에서 다양한 활용이 가능하도록 KRF (Korean Reach File) 설계안을 개선하여 제시하는 것을 목표로 하였다. 이를 위해 우선 미국 EPA RF(River Reach File) 사례를 검토하였고, EPA RF 설계 내역을 참고하여 개선된 KRF의 도형 및 속성 설계안을 제시하였다. 결과 검증을 위해 한강수계를 대상으로 KRF를 시범 구축하였으며, 총2,047개의 stream reach 분할이 가능하였고, 총 2,048개 지점에 대한 노드 생성이 가능하였다. 각 공간객체에 대한 고유식별자가 중복 없이 입력됨이 확인되었고, 이를 통해 유관 DB와의 자료연계에도 KRF가 활용될 수 있을 것으로 판단되었다. 또한 KRF에 위상정보가 강화되어 입력됨에 따라 향후 다양한 네트워크 분석에도 활용이 가능할 것으로 판단되었다. 향후에는 KRF를 이용한 수질모델링 및 자료관리, 공간분석 등 다양한 TMDL 실무 활용에 대한 연구가 필요하다.

In order to manage water quality efficiently and systematically through TMDL (Total Maximum Daily Load), the demand for the construction of spatial data for stream networks has increased for use with GIS-based water quality modeling, data management and spatial analysis. The objective of this study was to present an improved KRF (Korean Reach File) design as framework data for domestic stream networks to be used for various purposes in relation to the TMDL. In order to achieve this goal, the US EPA's RF (River Reach File) was initially reviewed. The improved design of the graphic and attribute data for the KRF based on the design of the EPA's RF was presented. To verify the results, the KRF was created for the Han River Basin. In total, 2,047 stream reaches were divided and the relevant nodes were generated at 2,048 points in the study area. The unique identifiers for each spatial object were input into the KRF without redundancy. This approach can serve as a means of linking the KRF with related database. Also, the enhanced topological information was included as attributes of the KRF. Therefore, the KRF can be used in conjunction with various types of network analysis. The utilization of KRF for water quality modeling, data management and spatial analysis as they pertain to the applicability of the TMDL should be conducted.
