| Research Abstract |
Osaka area (Akita Prefecture) was selected as a model field for this study, where is representative mining are in Japan. Watershed of the Kosaka river was subdivided into polygons for the upstream to downstream, and we have six monitoring points along the Kosaka main stream for sampling and measuring of river water flow.
By using GIS (Geomorphological Information System), we analyze land utility of the area, heavy metal concentration in river water and their relationship between old mines and PRTR factory. We could find undiscovered heavy metal sources by those analytical method, which is closely related untreated of mine drainage of uncertain old mines.
