We have investigated the water balance and mass balance for four years in Maekawa River basin on the eastern slope of Mt. Norikura-dake. In this region, the precipitation frequency is high from the rainy season to the autumn. The maximum base-flow discharge occurs in the spring snowmelt season. The pH and electric conductivity of the river water decline rapidly with the beginning of the snowmelt runo and temporarily decrease when the discharge increases temporarily in the rainy season or during a typhoon event. The Cl concentration of the river water increases in the early stage of snowmelt season since there is a considerable amount of sea salt in the snow. In addition, the NO concentration of the river water increases when the rainfall increases the discharge. The major ion concentration of the river water, except Cl and NO almost synchronizes with the change in the electric conductivity. In the mass balance of cations, the runo rate from the river basin considerably exceeds the atmospheric deposition rate to the river basin. This is because there is extremely much elution of ions from new volcanic rocks and soils. Further, the atmospheric deposition rate of NO is larger bigger with the biological consumption in the river basin than the runo rate from the basin.
