Hydraulics in Porous Media

Objectives

Specialization of the basics of fluid mechanics and continuous media ... to the problems of porous media, with applications in underground hydraulics, hydrology of soils and groundwater, and / or in geotechnics - deformable porous media (depending on the year).

Description

Bases:

• Porous media, porosity, void ratio, dry bulk density, particle size
• Hydrostatic saturated and unsaturated porous media; water retention curve
• Hydrodynamics: from Navier-Stokes to Darcy; Darcy's law; conservation equations
• Deformable porous media: compressibility, effective stress / Terzaghi, etc.
• Review of different flow equations (local or vertically integrated)
• Recap: "Porous Media in a Nutshell".

Hydrology and environment:

• Infiltration and puddling (genesis of 'hortonian' floods)
• Exfiltration of groundwater and tablecloth-river interactions
• Groundwater drainage problems (examples in hydrology and / or civil engineering)

Civil and geotechnical engineering (depending on the year):

• Compaction, consolidation, subsidence
• Earth dikes (leak rates)
• Tunnels and underground excavations (pumping, seepage, leakage flow)
