[Furuta, Kataoka, Shikano, Hayama]
In order to measure the quantity of water flowing through the KAGRA site, we set 4 water gauges(HOBO U-20):
o Water pool near the New atotsu entrance.
o Water pool at the X arm, ~1km from the X end.
o Water pool at the Y arm, ~1.5km from the Y end.
o Water pool behind the Yend
We start measurement of the quantity water at the sampling periods of 5 minutes.
The measurement will run over the iKAGRA second run, at least.
