Abstract

Abstract

pedon is a Python package for describing and analyzing unsaturated soil hydraulic properties.It provides an object-oriented framework for soil hydraulic models, along with tools for retrieving parameters from soil parameter databases, applying pedotransfer functions, and fitting soil hydraulic model parameters to measurements. Statement of needResearchers and engineers working with unsaturated soils need estimates of soil hydraulic model parameters for groundwater models.pedon provides a Python toolkit that brings together soil hydraulic models, parameter databases, pedotransfer functions, and fitting routines, making soil analysis faster, more reproducible, and easier to integrate into existing groundwater modeling workflows.
