Annual data compilation of water balance observation in the Regional Hydrogeological Study Project (RHS Project); For the fiscal year 2009

Takeda, Masaki ; Takeuchi, Ryuji  

At the Tono Geoscientific Research Unit, the subsurface water balance observation has been carried out in order to estimate groundwater recharge rate for setting the upper boundary conditions on groundwater flow simulation and to obtain data for the calibration of the hydrogeological model. In the subsurface water balance observations, rainfall data and river flow rate have been observed in the Garaishi river area and the Hiyoshi river area. The missed data and data error in the monitoring data from the fiscal year 2009 were complemented or corrected, and these data were compiled in data set. Both of the observation data and compiled data are included in the data set, and the data set is recorded on DVD-ROM.
