cooper_jacob_calculate_parameters: cooper_jacob_calculate_parameters

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

Description

Function to calculate the transmissivity, storage coefficient and radius of influence using the Cooper-Jacob solution

Usage

cooper_jacob_calculate_parameters(ptest, par, hydraulic = TRUE)

Arguments

ptest	A pumping_test object
par	list with the value of a (slope) and t0 (Intercept) of the straight line fitted to the drawdown data
hydraulic	Logical flag to indicate if hydraulic parameters are calculated. If False, the the statistcal parameter are calculated.

Value

A list with the transmissivity, storage coefficient and radious of influence
