Stehfest Inversion Model for Constant-Head Semi-Analytical Solutions (Based on Python)

Year: 2025

Type: article

Abstract: This repository contains two Python codes implementing the inversion of dimensionless drawdown and dimensionless discharge for constant-head tests (CHT) in confined double-porosity aquifers. The scripts perform Laplace-domain evaluation of the analytical semi-solution and apply the Stehfest numerical inversion to transform the results into the time domain. The codes are fully modular and can be adapted to analyze other pumping or dewatering configurations governed by Laplace-domain formulations.
