Objectives
Students will be well prepared to work for environmental consultancy firms, environmental research laboratories, water development organizations, water management, regulatory agencies or to continue to a Ph.D. program.
The students will be able to:
- Interpret geological and hydrological data to identify aquifers and aquitards, to locate areas of recharge and discharge and to determine groundwater flow directions and pathways.
- Apply groundwater flow equations to determine the aquifer response to groundwater pumping, to evaluate flow in local and regional groundwater systems, and to estimate aquifer properties through the interpretation of pumping tests and piezometer tests.
Subject matter
1. Water. Hydrology and Hydrogeology. The hydrological cycle. Precipitation and evaporation. Formation and measurement of precipitation. Evaporation and transpiration. Evapotranspiration.
2. Aquifers. Properties of aquifers. Porosity and permeability. Darcy’s experiment. Hydraulic conductivity. Water table. Water table and potentiometric surface maps. Aquifer characteristics.
3. Principles of groundwater flow. Darcy’s law. Equations of groundwater flow in confined and unconfined aquifers.
4. Groundwater flow to wells. Determining aquifer parameters from time-drawdown data. Aquifer-testing. Aquifer tests with observation wells.
5. Physical and chemical properties of water. Water quality and groundwater contamination. Dissolved constituents and suspended material in the water. Classification of water. Total dissolved solids. Dominant ions. Water use and water origin. Groundwater pollution. Saline intrusion. Nitrate pollution and other causes of groundwater pollution.

Teaching method
Lectures and field work. In the classes the students are invited to discuss problems and case studies related with the evaluation of water resources, groundwater flow and water quality.
Interpretation of aquifer tests and estimation of aquifer parameters (T, S, K, b and R).
Field work. Geological and hydrogeological interpretation of the study site and collected data.
The students are evaluated according to their knowledge evolution along the course, on the quality of the field work and on the result obtained in the exam.
Evaluation method
The students are evaluated according to their knowledge evolution along the course, on the quality of the field work and on the result obtained in the exam.
