Falling head infiltration tests at bench scale were carried out to estimate the hydraulic properties of the materials under unsaturated conditions. Theoretical solutions and model predictions were compared with experimental data, which demonstrated the dominant control of macro-porosity on water flow and infiltration rate. Permeability test under saturated conditions was performed with constant and falling head tests.
In particular, our experimental results indicate that the wetting front propagates mainly through the macropores with a gravity driven flow velocity higher than the diffusive flow through the micropores.
An integrated study on the hydraulic properties of homogeneous calcarenites with a complex pore network is presented, aimed at assessing water infiltration and retention mechanisms, starting from dry to wet conditions under high water inflow.
Grainstones and packstones were used as material for testing and model set up.

Nicotera The proceedings of the workshop are published by : Tarantino, A. The effect of texture, degree of saturation and boundary conditions on infiltration dynamics is discussed. The conference was organised under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering ISSMGEthe National German Geotechnical Society DGGT and funded by the German Research Fund DFG.
Falling head infiltration tests at bench scale were carried out to estimate the hydraulic properties of the materials under unsaturated conditions.
Unsaturated hydraulic relationships such as the soil water retention curve SWRC and hydraulic conductivity function were examined.
