✦ Synopsis

Published by the American Geophysical Union as part of the Water Science and Application Series.

Considerable basic and applied research has been and continues to be focused on understanding and evaluating the influence of land use changes, such as urbanization or forest management, on watershed hydrology and geomorphology. The motivation for the research is to develop land use policies that minimize adverse impacts and maintain the biodiversity and sustainability of human influenced ecosystems.

In this monograph we present recent data and interpretations from a variety of approaches on how forest management and urbanization have influenced the hydrologic and geomorphic responses of watersheds. Included are field studies of paired experimental manipulated watersheds, plot studies, and spatially distributed models. While much of the material within the monograph concerns watersheds in a defined locale, the Pacific Northwest, the methods and management approaches also provide guidance for land use in other regions with similar hydro-climactic-geomorphic-ecological settings.Content:
