boulton_calculate_parameters: boulton_calculate_parameters

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

Description

Function to calculate the hydraulic parameters of the Boulton model

Usage

boulton_calculate_parameters(ptest, par, hydraulic = TRUE)

Arguments

ptest	A pumping_test object
par	List with the parameters a (slope), t0 and t1 are the intercepts of the straight line fitted to the drawdown using the Cooper-Jacob method for early and late times respectively.
hydraulic	Logical flag to indicate if hydraulic parameters are calculated. If False, the the statistcal parameter are calculated.

Value

A list with the values of transmisivity (Tr), storage coefficient(Ss), Drainage Porosity (omegad) and radius of influence (radius_influence)
