Learning Goals

The objective of this course is to inform the students about the way groundwater circulates, the typology of aquifers, and about the interpretation of flow tests and the calculation methods of the aquifer hydrodynamic parameters.
Other of the objectives is to give information about the aquifer distribution in continental Portugal.

Theoric classes:
Hydrogeology: concepts. Distribution of water resources on the Globe.
Hydrological cycle and water balance.
Aquifer types.
Types of porosity.
Storage coefficient (S).
Physical proprieties of the fluids. Basic equations of hydrodynamics.
Circulation in porous media.
Type of groundwater uses and contamination.
Oscillations of the piezometric groundwater levels.
Hydraulics of groundwater impounding.
Type of wells and flux generated.
Hydraulics of complete wells.
Flow tests.
Hydrogeology of Portugal.

Practical classes:
Granulometric analysis. Calculation of the Uniformity Coefficient (U). Calculation of the permeability based on the Hazen formulae. Horizontal and vertical permeability.
Geologic and hydrogeologic profile based on drilling reports.
Graphics flow/drawdown, specific flow/drawdown. Graphics time/flow and time/drawdown. Distinction between
phreatic and confined aquifers.
Flow tests.

Teaching Methods

Theoric and practical classes, including, when possible, a field visit to observe a drilling to get groundwater. Tests and written examines of the theoric and practical components.
