hantush_jacob_well_function: hantush_jacob_well_function

In khaors/pumpingtest: R Package for the analysis and evaluation of pumping tests

hantush_jacob_well_function

Description

Well function of the Hantush-Jacob model

Usage

hantush_jacob_well_function(td, par)

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 \beta = \frac{r}{4} \sqrt{\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
