Assessing the impact of groundwater abstractions on river flows
Published:January 01, 2002
Groundwater abstractions affect the water balance in catchments of rivers in hydraulic continuity with groundwater and may lead to reductions in river baseflow. The Environment Agency issues licences for groundwater abstractions and takes into account the risk of such adverse impacts when deciding whether to grant licences and what conditions to associate with each licence. Assessing the impact of a particular licence is a difficult task, but analytical solutions to idealizations of the complex river-aquifer interaction can help guide such judgements. This paper presents a brief review of available analytical solutions and discusses their applicability to real groundwater systems....

Sustainable Groundwater Development
Sustainable development of groundwater resources is a key environmental and social issue for the future. To manage groundwater resources efficiently it is necessary to include protection of springs, river flows and water levels dependent on groundwater discharges, while concurrently maintaining abstractions for water supply and economic benefit. Obtaining this balance between human and environmental needs, and protecting valuable groundwater resources from over-exploitation and pollution, presents a challenge to hydrogeologists that is reflected in the approaches and case studies contained in this volume.
This volume should be of interest to researchers, regulators and practitioners in hydrogeology as well as postgraduate students following courses in hydrogeology, water resources engineering and environmental management.
