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.

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.

Power parameter

Given scattered measurements — rainfall gauges, soil samples, air-quality sensors — inverse-distance weighting estimates values everywhere in between. Each sample's influence falls off with distance raised to a power: a low power gives smooth, blended surfaces; a high power makes each sample dominate its neighborhood in sharp bull's-eyes. The workhorse of GIS mapping.

Governing equation

\overset{z}{^} (x) = \frac{\sum _{i} w _{i} z _{i}}{\sum _{i} w _{i}}, w_{i} = \frac{1}{d _{i}^{2.0}}

Reading this result: At power 2.0 nearby samples win but distant ones still contribute — a balanced surface between smooth and spiky.

About this simulation

The full Groundwater Contamination tool models a rainforest with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
