Description

Well function of the Hantush-Jacob model

Usage

1

Arguments

td

Dimensionless time

par

List with the beta parameter and the coefficients used in the Stehfest inversion approach. The beta parameter is defined as

β = \frac{r}{4} √{\frac{k_{h}^{'}S_{s}^{'}}{TS}}

where T and S are the transmissivity and storage coefficient of the aquifer, and k_{h}^{'} and S_{s}^{'} are the vertical hydraulic conductivity and the Storage coefficient of the aquitard respectively.

Value

The value of the dimensionless drawdown of the Hantush-Jacob model
