HYDRAULICS OF GROUNDWATER - SYLLABUS

Basics of hydromechanics.

Groundwater; porous media, aquifers, basic notions.

Flow of groundwater; Darcy's law, volumetric flux density, hydraulic conductivity, non-Darcian flow, anisotropy, hydraulic head, variable density.

Governing equations; continuity equation, steady-state flow, evolution problems, specific storativity, general equation of saturated flow, 2D problems, initial and boundary conditions, free and movable boundaries.

Hydraulics of aquifers; the Dupuit-Forchheimer approach, discharge per unit width, transmissivity, storativity, the Girinskii potential.

Unsaturated zone; negative pressure head, water content, retention curve, van Genuchten's equation, the Darcy-Buckingham law, Mualem's equation, Richards' equation and corresponding boundary conditions.

Transport phenomena; phases and components, molecular diffusion, advection, dispersion, dispersivity, coefficient of dispersion, advection-dispersion equation, sources, degradation, decay, sorption, general transport equation.
