A desire to minimize the ecologic impact of the development and use of natural resources is now firmly established. It is, therefore, vitally important for engineers and scientists to thoroughly understand the
nature of a particular environment before attempting to manipulate it or govern its uses. This book deals with one crucial resource-water. There is sufficient material for either a one- or a two-semester,
beginning course in hydrology. Although primarily intended for undergraduates, the content is sufficiently rigorous for a first graduate course as well. And because the book emphasizes hydrologic principles
and their practical application to realistic problems, practitioners should find the material useful as a reference.
