On minimum relative entropy concepts and prior compatibility issues in vadose zone inverse and forward modeling

A comprehensive stochastic approach for forward modeling of the state variables in the vadose zone as well as for inverse modeling of the hydraulic parameters is proposed and applied to a field site in Napa Valley, California. The approach combines the Richards equation and the van Genuchten–Mualem soil models, with initial and boundary conditions provided by geophysical and meteorological measurements, into a Bayesian formalism, which allows...
