This paper presents new software for analyzing the hydrological characteristics of drainage systems around tailings dams. The Adaptive Stormwater Infrastructure(ASI) algorithm, which incorporates a priori information on man-made water-handling structures with a Digital Elevation Model(DEM), was modified to consider effective rainfall for grid-based hydrological analysis. The ArcObjects programing using Visual Basic.NET was carried out to implement the software as an extension toolbar in ArcMap(part of ArcGIS software package). Application of the software to the Sangdong tailings dam revealed that the software can analyze surface runoff patterns during rainfall by considering both surface and underground hydraulic structures. The software is superior to a conventional hydrological analysis tool used in previous studies in terms of providing more reasonable hydrological information on a watershed of tailings dam. It is expected that the software can be effectively utilized to support the design of hydraulic structures in tailings dams.
본 연구에서는 광미댐 인근 지역의 수문 분석을 위해 사용할 수 있는 새로운 소프트웨어를 개발하였다. 수치지형모델과 인공 수리 구조물에 대한 사전 정보를 결합할 수 있는 ASI 알고리듬을 개선하여 격자 기반의 수문 분석시 지역의 유효 유량 자료도 고려할 수 있도록 하였다. 소프트웨어 구현을 위해 Visual Basic.NET을 이용한 ArcObjects 프로그래밍을 수행하였으며, 그 결과 ArcGIS 소프트웨어의 제품군 중 하나인 ArcMap에서 확장 툴바 형태로 소프트웨어를 활용할 수 있었다. 개발된 소프트웨어를 상동광산 신광미댐에 적용한 결과 지형뿐만 아니라 지상, 지하 배수시설을 함께 고려하여 수문 분석을 수행할 수 있으며, 기존 연구에서 사용되었던 일반적인 수문 분석 도구와 비교할 때 보다 합리적인 분석 결과를 얻을 수 있었다. 본 연구에서 개발한 소프트웨어가 광미댐 배수시설 설계를 지원할 수 있는 도구로서 유용하게 활용될 수 있을 것이라 기대한다.
