Objectives
Groundwater is an important component of the hydrological cycle. Nevertheless, teaching and practice of Civil Engineering have been traditionally focused on the study, and use, of surface water. However, the growing relevance of groundwater issues — being either the dimension of the existing reserves, and/or the over exploitation and contamination of these reserves — justifies a major attention to the whole set of issues that embody the Hydrogeology (or Subsurface Hydrology).
Groundwater science is a highly multidisciplinary field, with contributions from several areas of knowledge: Geology, Environmental Sciences, Physics, Chemistry, Biology, Resources Management, etc. Consequently, its study demands teams with experts from different areas, in which those with a sound education on relevant issues, and a fair knowledge on the others, will play a leading role. This course on Hidrogeologia (Hydrogeology) is intended to provide the students with a solid formation on Groundwater Hydraulics and Groundwater Transport as well as to introduce them to the legal framework of exploitation and management of groundwater.
