The runoff is a very complicated phenomenon. In this paper, the fundamental equation of runoff, especially during flood, was hydraulically and hydrologically derived, based on the Hayami's excellent theory of runoff. An analog computer for runoff, whose computing circuit was directly represented by the equation analogous to the above one, was designed and constructed. Using this computer, the author obtained some solutions and discussed the characteristics of runoff. As an example, the result of computation for the Yura River basin was explained and it was ascertained that this computer had a good accuracy and was very available for engineering problems in hydraulics and hydrology.
