Book Description
Riparian plant assemblages give clues of the conditions of the soil and other physical characteristics of their stream-side environment. The plight of the spring/summer, and fall Snake River chinook salmon has aroused interest in fish habitat and the effects of riparian plants on fish habitat. This study was launched to determine if riparian plant species assemblages could be used as an efficient assessor of fish habitat and the effects of land use on riparian areas and streams in the Payette National Forest in Central Idaho. Five plant communities are described. Stream attributes of streambank undercut width and streambank stability were different between communities, while fish habitat type and substrate particle size were not. Management implications for each plant community type were drawn from the current condition of the riparian area and stream attributes.

Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Description
In-stream and riparian habitat data were collected from 58 stations throughout Iowa between 1995 and 2001 for an ongoing study of interior river habitats. Out of 162 variables calculated for each station, data visualization software was used to select 37 variables that encompassed the majority of habitat variability and relationships between variables. This subset of variables was examined using univariate and multivariate methods, including Pearson correlations, linear regressions, ANOVAs, canonical correlations and a non-metric multidimensional scaling (MDS) ordination. Stream order significantly affected several riparian and stream size-related variables. Eleven in-stream, riparian and reach variables had significant regressions with drainage area. Only one variable, proportion of banks with canopy, had a significant regression with sinuosity. The axes of the 3-dimensional ordination used to plot habitat station similarities were multivariate expressions of stream size, rock versus wood cover and canopy cover. The ordination revealed that larger stations had decreasing levels of overall habitat heterogeneity. Canonical correlation analysis used to examine linkages between in-stream and riparian habitat variables revealed three significant canonical variables; one depicted a stage of the channel evolution model (CEM), the second linked the number of vegetation types to the number of cover types and flow classifications, the third canonical correlation reflected a process of riparian trees eventually becoming in-stream cover. Pervasive, intense agriculture with its associated channelization and sedimentation create a backdrop of profound alteration in shaping stream habitat in Iowa. The relationships we demonstrated among in-stream and riparian habitat characteristics in Iowa streams must be viewed in light of this backdrop of alteration.

Book Description
Fluvial Geomorphology studies the biophysical processes acting in rivers, and the sediment patterns and landforms resulting from them. It is a discipline of synthesis, with roots in geology, geography, and river engineering, and with strong interactions with allied fields such as ecology, engineering and landscape architecture. This book comprehensively reviews tools used in fluvial geomorphology, at a level suitable to guide the selection of research methods for a given question. Presenting an integrated approach to the interdisciplinary nature of the subject, it provides guidance for researchers and professionals on the tools available to answer questions on river restoration and management. Thoroughly updated since the first edition in 2003 by experts in their subfields, the book presents state-of-the-art tools that have revolutionized fluvial geomorphology in recent decades, such as physical and numerical modelling, remote sensing and GIS, new field techniques, advances in dating, tracking and sourcing, statistical approaches as well as more traditional methods such as the systems framework, stratigraphic analysis, form and flow characterisation and historical analysis. This book: Covers five main types of geomorphological questions and their associated tools: historical framework; spatial framework; chemical, physical and biological methods; analysis of processes and forms; and future understanding framework. Provides guidance on advantages and limitations of different tools for different applications, data sources, equipment and supplies needed, and case studies illustrating their application in an integrated perspective. It is an essential resource for researchers and professional geomorphologists, hydrologists, geologists, engineers, planners, and ecologists concerned with river management, conservation and restoration. It is a useful supplementary textbook for upper level undergraduate and graduate courses in Geography, Geology, Environmental Science, Civil and Environmental Engineering, and interdisciplinary courses in river management and restoration.

Book Description
This book describes the underlying water conditions and geologies that support viable riparia, illustrates the ecological characteristics of riparia, and discusses how riparia are used by human cultures as well as how riparia can be used to sustain environmental quality. In recent years riparian management has been widely implemented as a means of improving fisheries, water quality, and habitat for endangered species. This book provides the basic knowledge necessary to implement successful, long-term management and rehabilitation programs. - Treats riparian patterns & processes in a holistic perspective, from ecological components to societal activities - Contains over 130 illustrations and photos that summarize this complex ecological system - Synthesizes the information from more than 6,000 professional articles - Sidebars provide a look into ongoing research that is at the frontiers of riparian ecology and management

Book Description
As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.
