Accurate characterization of gas migration in soils and other porous systems is an important prerequisite to understand provisional (e.g., plant growth) and regulatory (e.g., public safety, climate change) services of different ecosystems. In this research seminar, experimental and numerical studies conducted in a wide range of soils including agricultural soil, pasture soils, landfills, urban soils, Arctic soils will be presented. An experimental and numerical insight on gas transport in selected porous substrates for space-based applications (for example to grow plants in Space Stations) will also be presented.
