Theis and Cooper-Jacob solutions (confined aquifer)
Hantush-Jacob solution (leaky aquifer)
Jacob-Lohman solution (artesian confined aquifer)
Boulton solution (phreatic aquifer)
Cooper solution (slug tests)
Agarwal solution (recovery tests)
Agarwal solution (tests with skin effects)
General Radial Flow (fractured aquifer)
Neuzil solution (pulse tests)
Papadopoulous-Cooper solution (large diameter wells)
Warren and Root solution (dual porosity aquifer)
Gringarten solution (single fracture)
Hvorslev solution (slug tests)
Bower-Rice solution (slug tests)
The estimation of the hydraulic parameter is achieved by different optimization algorithms including
Nonlinear least squares with the Levenberg-Marquart algorithm (package minpack.lm)
L-BFGS-B (package optim)
Simulated Annealing (package GenSA)
Genetic Algorithms(package GA)
Particle Swarm Optimization (package PSO)
Differential Evolution (package DEoptim)
Estimation of Distribution Algorithm using Copulas (package copulaedas)
with four possible objective functions:
Sum of Squares Residuals
