トリチウムによる降水の地下浸透量の推定 [in Japanese] Estimation of the rate of precipitation recharge to the groundwater by tritium measurements [in Japanese]
Access this Article
This paper presents the discussion on the balance of water and the transport of tritium, among three geohydrologic zones of Musashino groundwater basin. The discussion leads the estimation of the annual recharge to the groundwater from presipitation assuming the following data. 1) Time variation of tritium content in precipitation 2) Time variation of tritium content in the unconfind groundwater 3) Quantities of pumped out water from the confind groundwater 4) Tritium distribution of the whole basin In Musashino groundwater basin, this estimation gives the value of 0.50±0.16 m/y for the rate of precipitation recharge to the groundwater.
