湧水の挙動に関する研究 ―田川流域の地下水に関する研究(2)―

Abstract

The daily fluctuations of outflow from springs situated at the end of Kusano fan inthe basin of the River Ta, are analyzed theoretically in this paper.Since it was disclosed in the previous paper that the springs play an important roleon the behaviour of groundwater flow in the basin, two springs were selected to observethe outflow in 1968. As the result, it was made clear that the outflow is closely relatedto the discharge of the River Kusano.Fundamental equations for unconfined and confined aquifers were solved numericallyusing the technique of finite difference. As the result, the fluctuation in the rate ofoutflow from one of the springs was explained fairly well by this analysis, but anotherwas not. The reason for the latter is attributed that the man's factors were beyond ofthe consideration.
