| Research Abstract |
Monitoring of the amounts and the water qualities of effluent water from various land uses in rural area (paddy filed, crop-rotated paddy field, forest, resident area, and rural sewage treatment plant) is conducted elaborately including rainfall events in order to quantify the relationships between the amounts and the loads of effluent water from various land uses for various water qualities (LQ equations). It was possible to estimate the load and the concentration of the discharged water from a catchment based on LQ equations. Water management of the amount of effluent water from each land use would influence not only on the concentrations but also on ion balance of the discharged water from a catchment.
Focusing attention on radiocesium in discharged water, temporal change of mechanical composition of suspended solid in water during a rainfall event is very important factor.
