'I recommend the Encyclopedia of Hydrology and Water Resources to those that need quick, authoritative information.' Robert M. Hirsch, Chief Hydrologist, United States Geological Survey 'Some discussions provide the reader with more information in a six or seven page review than a complete text devoted to the topic ... The 100 or so authors and Dr Herschy have assembled a valuable work of reference, a good starting point for many searching for information on an unfamiliar area.' John C. Rodda, Hydrological Sciences-Journal des Sciences Hydrologiques, 44:2 (1999) 'a magnum opus ... no professional firm working in this area should be without a copy in the office. The book is an essential reference work for all major civic, university and research establishment libraries.' M.J. Hamlin, Birmingham University, Circulation, 61 (May 1999) '...this Encyclopedia is recommended for professional firms, university and research establishment libraries...the authors must be congratulated for concisely bringing together such a wealth of information and for its excellent presentation. The Encyclopedia is a unique publication of such type and a welcome contribution to hydrology and water resources literature.' W.G. Strupczewski and M. Osuch, Pure and Applied Geophysics, 158 (2001)
