FAQ

What is Time at which the Drawdowns were Measured when Storage Coefficient is Given?
The Time at which the Drawdowns were Measured when Storage Coefficient is Given is the time at which the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test. and is represented as t=S*ro^2/2.25*T or Time at which the Drawdowns were Measured=Storage Coefficient*Distance from Pumping Well to Point Intersection^2/2.25*Transmissivity. Storage Coefficient is the volume of water released from storage per unit decline in hydraulic head in the aquifer, per unit area of the aquifer, Distance from Pumping Well to Point Intersection where the Straight Line Intersects the Zero-drawdown line and Transmissivity is the rate at which groundwater flows horizontally through an aquifer.
How to calculate Time at which the Drawdowns were Measured when Storage Coefficient is Given?
