Opis

For centuries river channels have been modified by a variety of engineering methods for the purposes of flood control, land drainage, navigation and the prevention of erosion. The principal aim of this book is to make river managers aware of the environmental constraints and opportunities entailed in engineering designs, with the aid of worldwide examples. It is demonstrated that fluvial geomorphology can be useful in designing more natural channels.

Channelized Rivers Perspectives for Environmental Management Andrew Brookes Environmental Consultant, Reading, UK For centuries engineers have modified river channels in order to control floods, drain land, prevent erosion and improve navigation. The natural shape of many rivers has been dramatically changed, often with dire environmental consequences. This book demonstrates the role fluvial geomorphology can play in the design of river channels, both to lessen environmental impact and to enhance the success of channelization schemes. It considers the physical and biological impacts of channelization, the repercussions downstream and in the adjacent floodplain. Revised procedures and designs are proposed which minimize harsh environmental impacts. The interdisciplinary approach of the book offers river managers the opportunity to make more environmentally sensitive decisions in the course of their work. The book will be of great interest to geomorphologists, biologists and civil engineers working in the water industry.
