Web-GIS를 이용한 수문지형인자 추출시스템 개발 - 금강 유역을 중심으로 - = System Development for Extracting Hydrologic-Topographical Parameters in Kum River Watershed using Web-GIS

다국어 초록 (Multilingual Abstract)

Hydrologic-topographical parameters of a watershed need to use in hydrologic analysis and to support hydrologic model and to manage water resources efficiently. In this study, a system that can delineate Kum river sub-basin in real time and extract hydrologic-topographical parameters was developed under web environment using a web-based geographic information system (GIS). Though this system, users can easily obtain a watershed boundary by selecting outlet point and extract topographical parameters including watershed area, watershed circumference, the average altitude of watershed with certain web browsers. Also, users can obtain hydrological parameters including average SCS curve number through the overlay of landcover map, soil map and drain map utilizing grid computation into watershed.
