Bayesian methods for the identification of model parameters for water transport in porous media
Paola Stolfi, Elia Onofri, Gabriella Bretti
The structure of the nonlinear inverse problem arising from capillarity-driven imbibition in porous media is investigated, considering a degenerate parabolic PDE with compactly sup…
Dissolution of carbonate stones caused by CO2 pollutant: an erosion model
Elishan Christian Braun, Gabriella Bretti, Samuele Ferri +2
In this paper we introduce a new mathematical model describing the erosion process caused in carbonate stones by the dissolution of the porous matrix due to the penetration of carb…
Structural Identifiability and Comparative Calibration of Water Retention Curves for Imbibition in Porous Media
Gabriella Bretti, Maurizio Ceseri, Elia Onofri +1
This paper investigates the structural identifiability and a comparative calibration of four water retention curves (WRCs) within the framework of the Richards equation coupled wit…
Finite elements for the space approximation of a differential model for salts crystallization
Alessandra Aimi, Gabriella Bretti, Giulia Di Credico +3
This article investigates a space-time differential model related to the degradation of stone artifacts caused by exposure to air and atmospheric agents, which specifically lead to…
