Formulas to find Initial Constant Piezometric Head

Possible Drawdown in Confined Aquifer

Possible Drawdown in Confined Aquifer is the drawdown that would have occurred if the aquifer had been confined (that is, if no dewatering had occurred).

Symbol: s'

Measurement: LengthUnit: m

Note: Value can be positive or negative.

Formulas to find Possible Drawdown in Confined Aquifer

Drawdown

Drawdown is the difference in height between the natural water table (or potentiometric surface) and the water level in a well after groundwater has been extracted.

Symbol: h

Measurement: LengthUnit: m

Formulas to find Drawdown

Other formulas in Unsteady Flow in a Confined Aquifer category

Go Drawdown

s t = (\frac{Q}{4 \cdot π \cdot T}) \cdot \ln (\frac{2.2 \cdot T \cdot t}{r^{2} \cdot S})

Go Drawdown at Time Interval 't1'

s 1 = s 2 - ((\frac{Q}{4 \cdot π \cdot T}) \cdot \ln (\frac{t 2}{t 1}))

Go Drawdown at Time Interval 't2'

s 2 = ((\frac{Q}{4 \cdot π \cdot T}) \cdot \ln (\frac{t 2}{t 1})) + s 1

Go Equation for Storage Coefficient

S = 2.25 \cdot T \cdot \frac{t 0}{r^{2}}
