Groundwater is the largest freshwater reservoir on the planet. It feeds rivers and oceans, and in many parts of the world, including regions of the UK, it is the main, or only, source of freshwater. This module discusses aquifers and studies the role of the unsaturated zone in hydrogeology. Students will be introduced to the Darcian flow mathematical models of groundwater flow, and will gain an awareness of the tools and techniques available for groundwater investigation.

Students will develop an appreciation for the critical role that soil water plays in sustaining vegetation. For example, it can influence the structural properties of the ground. The module also introduces concepts of groundwater transport, and highlights the linkage between rivers and aquifers. It will address the modelling tools required for groundwater applications, and practical examples such as a field visit are used to support the material covered in lectures.
