Groundwater Well DrawdownLive

Thiem steady-state cone of depression

Controls

Presets

Pumping rate Q (m³/day)

Transmissivity T (m²/day)

Radius of influence R (m)

Pumping a well lowers the water table into a cone of depression. Under the Thiem steady-state solution the drawdown is s(r) = Q/(2πT)·ln(R/r): more pumping deepens the cone, higher transmissivity flattens it. Fundamental to well design, water supply, and contaminant capture.

▶ Run in Python

Data Inspector

Drawdown at well4.7 m

Drawdown at 50 m1.47 m

Radius of influence500 m

Governing equation

s (r) = \frac{Q}{2 π T} ln \frac{R}{r} = \frac{2000}{2 π \cdot 500} ln \frac{500}{r}

Reading this result: Drawdown is Q/(2πT)·ln(R/r): here it is about 4.7 m at the well and falls off logarithmically, so most of the depression sits in the first tens of metres.

Soil friction angle φ (°)

Soil unit weight γ (kN/m³)

Base width (m)

Rankine theory gives the active earth pressure behind a wall from the coefficient Ka = tan²(45−φ/2). The soil pushes with a triangular pressure resultant Pa acting at one-third the height. The wall must resist overturning and sliding with adequate factors of safety. Educational tool, not a geotechnical design.

▶ Run in Python

Data Inspector

Ka0.333

Active thrust Pa48.0 kN/m

FS overturning1.82

FS sliding0.81

Governing equation

K_{a} = tan^{2} (45 - \frac{φ}{2}) = 0.333, P_{a} = \frac{1}{2} K_{a} γ H^{2} = 48.0 kN/m

Reading this result: Sliding FS is 0.81, under the ~1.5 target — the wall could slide out. A wider base or a shear key would help.
