농촌유역의 오염부하량산정을 위한 범용적 GIS 및 데이터베이스의 구축

Development of Odinary GIS and Database for Calculation of Pollutant Load in Rural Areas

Pollutant load using unit load method is calculated by simply equation, especially, very useful in the area that didn't exist about water quality data. However, it takes long time to calculate pollutant load with area in which there is various pollutants and if the boundary of a basin altered, the work of calculation about pollutant load must be begun from the first again. Therefore, a Total Daily Load Program(TDLP) was developed to calculate pollutant load automatically in rural area. The TDLP includes a geographic information system(GIS), relational database system(RDBS), User Interface. This Program can provide user with creating a boundary of the basin that user is concerned with to satisfy the water quality regulations and calculating daily load for various pollutants. The effort was conducted to apply the developed TDLP to calculating pollutant load in rural basin called Bok-ha river.
