In this report we describe an application of the variational method to obtain the runoff-kernel deterministicly and it's applicative examples. Especially, we introduce the coefficient of discharge and the lag time as a parameter on the assumption of a functional that the effect of storage is minimized by the present variational principle, so that the simple short-term runoff is supposed as a objective one. The authors' analysis on the linear response-system is applied to one experimental basin that ranges in a 0.40km^2 small watershed. Furthermore, we present a way of analytical theory to expand this analysis into a nonlinear one. Concerning the purpose, it is expected that these studies make for a better understanding on the substance of the unit hydrograph in rainfall-runoff process.
