On completion of this module, students should be able to:
outline the concepts of total porosity, effective porosity, hydraulic conductivity, transmissivity, hydraulic gradient, specific yield and storage coefficient;
explain the mode of occurrence of groundwater in different rock types;
assess the amount of groundwater stored in an aquifer and the volume that can be exploited;
calculate rates of flow and flow speeds of groundwater in aquifers in simple settings using Darcy's law;
determine the hydraulic conductivity of unconsolidated material in the laboratory;
analyse a steady-state pumping test in a confined aquifer to obtain transmissivity;
analyse a simple non-steady state pumping test in a confined aquifer to obtain transmissivity and storage.
This module aims to provide students with an understanding of the origin and occurrence of groundwater, its quantitative evaluation, and its role and importance in the hydrological cycle.
Lecture content includes:
Groundwater flow and Darcy's law; pumping tests (Thiem and Theis solutions); aquifer types and their response to recharge and abstraction, pollution and protection of groundwater and aquifers.
Practical content includes:
Demonstration of Darcy's law and measurement of hydraulic conductivity with constant head apparatus; calculation of flow, flow to a well; analysis of simple pumping tests; hydrogeological maps and flow systems.
Recognition of groundwater discharge and baseflow into surface waters.
This module is designed to provide students with a conceptual, factual and practical introduction to the functioning and prediction of complex hydrological systems, with particular reference to quantitative computer simulation of these systems as practiced by water management agencies in the UK and internationally. All components of the hydrological cycle will be considered, along with water quality models, lumped hydrological, semi-distributed hydrological, fully distributed hydrodynamic and the new generation of coupled atmospheric-hydrological flood prediction models.
