低平農地における雨水流出のパラメトリックモデル

In studying the mechanism of runoff processes in low-lying agricultural lands, it is an important problem to express mathematically the phenomenon of hydrologic transformation and time lag from rainfall to discharge induced to the effect of storage and inundation.
This paper described such a runoff phenomenon being apt to occur the remarkable flooding. The outline of the study was as follows :
(1) The parametric model of rain-water flow in such an agricultural area was proposed and the method of runoff analysis was discussed about the mathematical model having two parameters which expressed the conveyance of drainage channel and the initial water storage in the basin.
(2) After the characteristics of the runoff were described in the model basin applying the method, the adaptability of the runoff model was examined on the observed runoff data and its usefulness was made clear.
