We analyze and evaluate a correlation of total coliform and land use data on a monthly basis in the downstream of Oita River. In addition,we analyze and evaluate the optimal range to use laser profiler data from the total coliform's observation points. As a result of the analysis, we found that the correlation of building land is high in land use, and the correlation of total coliform of March and June is high in the case of using land use data of about 2.0 km radius.
