We additionally propose the new approach, which can take into account the surfacesubsurface runoff as well as groundwater runoff in the subbasin runoff modeling, using the two-cascade storage routing model. The two runoff components can be separated via use of the numerical filter so that the optimal parameters of each component can be independently identified. Especially, the parameters of groundwater runoff component can be automatically determined by the known parameters and hence computational burdens can be significantly reduced. We show that the proposed approach can remarkably improve the reproduction of flood hydrographs, when the flood flows are routed through both of subbasin and channel phases.}, pages = {151--156}, title = {成分分離に基づく流域・河道追跡のための貯留関数モデルの同定}, volume = {46}, year = {2002}, yomi = {ナカツガワ, マコト and ホシ, キヨシ and ハシモト, ノリヒデ} }
