hantush_jacob_calculate_parameters: hantush_jacob_calculate_parameters

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

Description

Function to calculate the hydraulic parameters of the Hantush-Jacob model

Usage

hantush_jacob_calculate_parameters(ptest, par, hydraulic = TRUE)

Arguments

ptest	A pumping_test object
par	A list with the values of a (slope) and t0 (Intercept) of the straight line fitted to the drawdown data using the Cooper-Jacob approach, and lambda is the leakage factor.
hydraulic	Logical flag to indicate if hydraulic parameters are calculated. If False, the the statistcal parameter are calculated.

Value

A list with

• Tr = Transmissivity

• Ss = Storage coefficient

• Ka = Aquitard Hydraulic Conductivity

• radius_influence
