Basin specific yield calculation which consider groundwater level change

This research recognized change of the specific yield(Sy) by groundwater level in small size tube well of the farm village area. The result research basin aquifer could quality that the specific yield according to geological quality of aquifer changes showed value of $0.0004{\sim}0.081$ extents according to groundwater level decline.
