AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

COURSE AIMS:

1. To introduce the various hydro-geological processes and the relevant analytical methods for engineering analysis
2. To overview the main applications of groundwater flow principles as relevant to geotechnical engineers
3. To introduce the fundamental aspects of capillarity in soils

​LEARNING OUTCOMES:

1. Apply analytical tools and modelling techniques to the prediction of hydro-geological variables
2. Evaluate the main soil parameters that affect the relationship between rainfall and ground infiltration
3. Evaluate sustainability of groundwater abstraction schemes with reference to the occurrence of pumping-induced subsidence
4. Describe the effects of suction and capillarity in unsaturated soils

TEACHING METHODS

The course will take place on-line due to the covid-19 health emergency. Details on the modalities of delivery of the lectures are provided on the classroom page of the AulaWeb internet site.
