Slug test solution (McElwee and Zenner 1998)

The McElwee and Zenner (1998) solution for slug test in a confined aquifer, assuming laminar flow in wellbore and Darcian flow in aquifer.

A model of a single well slug test was developed by McElwee and Zenner (1998). This model shows the drawdown in the test well.

Assumption and conditions:
1, laminar flow in wellbore
2, darican flow in aquifer
3, aquifer is confined
4, radius does not change in wellbore, casing radius is equal to screen radius, minor loss is negligible.
5, Hvorslev model is used in aquifer

Run ''DrawdownExample'' to plot three curves of drawdown by using three different conducitities (K=5e-3, 2e-3, 5e-4) in an aquifer.
