The fundamental knowledge in chemistry, physics, mathematics.
The basic knowledge of geology and applied geology.

To provide the knowledge and techniques for the practical application of hydrogeology the main issues geological and environmental applications as well as research , evaluation, utilization and protection of groundwater resources , considered in their qualitative and quantitative aspects.
Acquiring the knowledge to conduct hydrogeological investigations with applications to practical cases. Ability to perform and interpret hydrogeological mapping. Choosing the most suitable techniques for solving hydrogeological problems in the field of applied geology and the environment.

Revision of the hydrogeological basic information (water cycle, rocks hydrogeological properties, confined and unconfined aquifers, Bernoulli's principle, Darcy’s law, transmissivity, storage coefficient, isopiezometric map, wells and springs).
Discharge measurement in streams and springs: flow meter, measuring weirs, tracer
injections, discharge rating curve.
Alluvial, fractured and karstic aquifers.
Determination of hydraulic conductivity in the fractured rock through geostructural survey.
Use of hydrochemistry and isotopic hydrology in hydrogeology.
Spring hydrograph analysis. Recession curve. Discharge coefficient of an aquifer (Maillet and Tison approaches). Spring hydrograph responses to the infiltrative process (prevailing replacement, piston effect and homogenization).
Groundwater sampling methods (wells and springs).
Well pumping tests: aquifer pumping test and step drawdown test (Dupuit, Thiem,
Theis, Jacob approaches). Transmissivity determined from specific capacity.
Borehole permeability tests (Lefranc, Lugeon, slug-test).
Sources of contamination of the groundwater. Pollutants migration and transport into groundwater. Acceptable quality for drinking water, industrial and agricultural.
Saltwater intrusion in coastal areas.
Delineation of groundwater protection zones (wells and springs).
Groundwater's vulnerability evaluation methods (Drastic and Sintacs).

The course comprises lectures, practicals and fieldwork.
