'… an excellent addition to the growing knowledge base of groundwater science and technology. … By placing an emphasis on method, this book provides clear concepts of the recharge process and associated methods that stem from more than 800 peer-reviewed references. …Healy's book offers a comprehensive yet focussed treatment in both theoretical and practical aspects through a wealth of cited references. … the book comprehensively documents some forty methods that can be applied for estimating groundwater recharge in a range of hydrological scenarios. Perhaps for the first time, both theoretical and practical aspects are considered within the conceptual framework. It makes the book an excellent reference for both students and practising hydrogeologists to consult in their endeavour to better understand recharge estimation.' Hydrogeology Journal
