Subject fundamentals
The course aims at providing basic and advanced quantitative knowledge related to groundwater flow and contaminant transport in aquifer systems. Topics include the description of fundamental properties related to storage, transport and water release in aquifer systems. Analytical solutions of the flow equations are analyzed and provided in order to derive hydrodynamic parameters of the aquifer system and well tests are described in order to derive well productivity and efficiency.
In the second part of the course, the most important chemical and physical properties of the most common contaminants will be described therefore the transport mechanisms and the analytical solution of the contaminant transport equations will be given. The last part of the course will be dedicated to the characterization and remediation of contaminated aquifer systems.
Expected learning outcomes
Provide basics and advanced knowledge in the groundwater engineering field. The student should be able to approach a flow and contaminant transport problem with a quantitative approach.
Fundamental properties: storage coefficient, hydraulic conductivity. Hydrodynamic behaviour of different aquifer systems. Darcy’s Law, piezometric reconstruction.
Differential equation of flow in aquifer systems. Analitical solutions for radial geometry for confined, semi-confined, unconfined aquifers. Aquifer characterization by means of constant rate aquifer tests, recovery tests, slug tests, other methods.
Well tests and determination of the well efficiency. Optimization of a water well system. Aquifer vulnerability and well head protection areas.
Chemical, physical and toxicological characterization of the most common contaminants present in the subsurface. Phenomena of transport of contaminant in aquifer systems: advection, hydrodynamic dispersion, adsorption, radioactive decay, biodegradation, other processes. Partial differential equation of mass transport. Analytical solution for conservative and reactive tracers. Propagation of non-aqueous phase liquid contaminants. Characterization of contaminated sites: unsaturated and saturated zone sampling. Risk based corrective actions. Remediation of contaminated aquifers.
