Abstract

The forthcoming European Union Water Framework Directive has increased awareness of the need to evaluate the impacts of groundwater abstraction on the environment. The Environment Agency of England and Wales is responsible for water resource management, which it achieves primarily by operating a formal abstraction licensing system. Judgements made on applications for groundwater abstraction licenses need to be both systematic and defensible. A novel approach has been developed in a project for the Environment Agency which uses a combination of numerical model simulations of generic river-aquifer systems and neural networks to quantify the impacts on river flows. This approach provides a model which is very fast to run, while retaining the advantage of numerical methods of being able to represent complex conditions. The outcome of the project is a user-friendly Graphical User Interface (GUI) and embedded neural network software, which is designed for use by abstraction licensing officers. The approach is illustrated using a case study.
