The concentration in both rivers changed due to land use of the catchment area and the seasonal. It is estimated the load from monthly data of river flow and survey concentration data. Total water flow rate changed due to snowfall, snow melt or increasing of summer rainfall has been confirmed that it effected the load of nitrogen in each river; especially nitrogen load was high from March to April and from July to August. According to the flowing down, nitrate (NO₃-N) and ammonia nitrogen (NH₄-N) with anthropogenic source was increased.
