With the increasing pressures on the availability and exploitation of fresh water resources through population increase, pollution and degradation of resources, and variations in distribution from regional and global change in the climate, compilation of knowledge in this area has become a prerequisite for education and training of practising and research hydrologists. The Encyclopedia of Hydrological Sciences is the definitive research level multi-volume treatment of this important topic.

McGraw-Hill's world-renowned annual publication continues its tradition of making information on the latest advances in science and technology accessible to non-specialists through concise, well-illustrated articles.
