resources of the Library at the University of East Anglia are appreciated for providing the necessary literature with which to compile this book. If this were not enough, we are indebted to Tim Atkinson, Richard Hey, Alan Kendall and Helen He for helping form the content of this book through the years spent together teaching and examining undergraduate and postgraduate students in hydrology and hydrogeology in the School of Environmental Sciences at the University of East Anglia. We are also grateful to the editorial team at John Wiley & Sons Limited for their guidance and support during the publication process. Last but not least, we again especially thank Cathy, Laura, Rebecca, Sylvia, Ronja, Kailash and Nico in supporting our endeavours in hydrogeology and for their patience during the time spent preparing this new edition.
