Abstract

In this research, the authors developed a method to estimate contaminant source areas of nonpoint load by analyzing the time series environmental impacts data in the river and the change of the time series rainfall distribution of the river basin, and focused on the outflow of nonpoint load mainly by the rainfall. In this research, TCBM, water quality data, RADAR rainfall data and GIS are combined. At first, the authors made a map that was colored in accordance with coefficients of correlation for each mesh to analyze, then considered the contaminant source areas by this map and GIS data (ex. Land used data, Altitude data etc.).
