• Groundwater table of eight wells in Konan aquifer substantially moves up and down in a year. Employing multiple regression analysis, seasonal movement of groundwater table is well formulated, using daily rainfall, near by Monobe River stage, daily mean atmospheric pressure, daily mean air temperature, daily mean relative humidity, daily mean wind speed, daily amount of global solar radiation, Seasonal Factor (SF, a dummy variable, and equals to unity during winter, i. e., from 1^<st> of January to 22^<nd> of March, and equals to zero from 1^<st> of April to 1^<st> of November), Weir Factor (WF, a dummy variable specifically for two wells, namely well No.3 and No.4, if the rubber dam on the Koso River near two wells is up, WF=1, and if down, WF=0). Data from November, 2001 to October, 2002 is used for parameter identification (the period is hereafter called "period of identification"), and accuracy of the model is verified using the data from November, 2000 to October, 2001 (the period is hereafter called "period of verification"). The latter data was observed once a week as a rule, and the former was observed almost every other day. To transform the data into daily ones, Spline interpolation (Sakurai. A., 1981) is utilized, and Spline interpolated data analyses and non-interpolated data analyses were compared. The best formulae developed here are Case No.4 (non-interpolation) for well No.1, 2, 3, 5, 6 and 7, and Case 7 (Spline interpolation) for no.4 and 8 in Table 5 respectively.
