[AHW24-P04] Change of rainfall runoff processes with the erosion of the volcano body: a case study of Mt. Ontake

*Kazuyoshi ASAI1, Maki TSUJIMURA2 (1.Geo-science laboratory, 2.University of Tsukuba)

Keywords:rainfall-runoff, Mt. Ontake, erosion, hydrograph separation, direct runoff, recharge rate

To clalify the change of rainfall-runoff processes with the erosion, long-term monitoring of stream-runoff and EC were conducted on two basins in Mt. Ontake.
