Research Abstract |
For the purpose of availability analysis of the flowpath-based method developed for estimation of dissolved organic carbon concentration of stream water in a granitic watershed, we applied this method to estimation of dissolved nitrogen concentration in a volcanic sedimentary watershed. The hydrometric observation in the volcanic watershed implied that the stormflow generation could depend on transient saturated subsurface flow via soil mantle. The analysis of concentration-discharge relationships in view of the difference of flowpaths showed that this method can be available for estimation of dissolved nitrogen concentration in the volcanic watershed.
