Ann L. Riley describes an interdisciplinary approach to stream management that does not attempt to control streams, but rather considers the stream as a feature in the urban environment. She presents a logical sequence of land-use planning, site design, and watershed restoration measures along with stream channel modifications and floodproofing strategies that can be used in place of destructive and expensive public works projects. She features examples of effective and environmentally sensitive bank stabilization and flood damage reduction projects, with information on both the planning...

Urban streams were perceived as little more than flood control devices designed to hurry water through cities and neighborhoods with scant thought for aesthetics or ecological considerations. Stream restoration pioneers like hydrologist Ann Riley thought differently. She and other like-minded field scientists imagined that by restoring ecological function, and with careful management, streams and rivers could...
