cooper_calculate_parameters: cooper_calculate_parameters

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

Description

Function to calculate the hydraulic parameters of a cooper solution for a slug test

Usage

cooper_calculate_parameters(ptest, par, hydraulic = TRUE)

Arguments

ptest	A pumping_test object
par	A list with the dimensionless wellbore storage coefficient (cd) and the Intercept of the straight line fitted to the drawdown data using the Cooper-Jacob approach (t0)
hydraulic	Logical flag to indicate if hydraulic parameters are calculated. If False, the the statistcal parameter are calculated.

Value

A list with

• Tr: Transmisivity

• Ss: Storage coefficient

• radius_influence: radius of influence
