Specific Capacity and Discharge into Well Relationship Formula Elements

Variables

Specific Capacity

The Specific Capacity is referred as amount of water furnished under a standard unit head.

Symbol: K_s

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Specific Capacity

Flow Discharge

The Flow Discharge refers to the volume of water passing through a particular cross-section of a river or stream per unit of time. It is typically measured in (m³/s) or cubic feet per second (cfs).

Symbol: Q_f

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value should be greater than 0.

Formulas to find Flow Discharge

Total drawdown at the well

Total drawdown at the well is the reduction in hydraulic head observed at a well in an aquifer.

Symbol: s_w

Measurement: LengthUnit: m

Note: Value can be positive or negative.

Formulas to find Total drawdown at the well

Other Formulas to find Specific Capacity

Go Specific Capacity under Unsteady Drawdown Conditions

K s = \frac{1}{(\frac{1}{4} \cdot π \cdot T) \cdot (\ln (2.25 \cdot T \cdot \frac{t}{{R w}^{2}} \cdot S)) + C 2 \cdot Q f}
