This volume presents a description of the river (a natural watercourse, usually freshwater, flowing towards an ocean, a lake, a sea, or another river), including its shape, size, organization, and action, along with a consistent theory that explains much of the observed character of channels.

Luna Leopold (1915-2006) is widely viewed as the foremost student of rivers of the 20th century. This volume presents a selection of informal essays written over the course of his long career. These essays complement his professional articles and books, and they illustrate how he became increasingly concerned with environmental degradation. Leopold argued forcefully that engineering solutions should be ethically framed as well as practical, and with that in mind, in 1969 he drafted the first environmental impact statement. He was awarded the National Medal of Science in 1991 Illus.

"By integrating the basics of hydrology and geomorphology with the practical formulation of policy, this book is intended for the general public, students of environmental studies, legislators, policy makers, and all others who are interested in the use, control, and management of water."--Jacket.
