Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored. This book will be of interest to graduate and professional research workers in environmental science, ecology and physical geography.

Available in PDF, EPUB and Kindle. Book excerpt: Urbanization is widely implicated in the alteration of ecosystem structures and processes, but the form of these changes can vary across geographic contexts. Regional differences in the impacts of urbanization may be particularly pronounced in riparian ecosystems, which are sensitive to the hydrologic disturbances that accompany urban development. My dissertation explores the influences of urban hydrology on riparian vegetation and soil properties in California’s understudied Mediterranean climate. I focus on the interaction of two key alterations associated with development in this region—stream channel incision caused by increased stormflow magnitude, and the presence of dry-season flow in formerly intermittent streams due to water inputs from urban landscape irrigation and wastewater. I hypothesized that channel incision would limit the effect of dry-season stream flow on riparian water availability, and investigated whether this interaction had long-term effects on riparian characteristics. I studied riparian zones along small streams in the Sacramento metropolitan region, where highly localized water inputs and a variety of stormwater practices and land use histories have created a mosaic of intermittent and perennial stream reaches across a gradient of channel incision. I asked whether channel incision interacted with dry-season stream flow to influence water stress in riparian trees, the composition of the riparian woody vegetation community, and riparian soil and understory vegetation characteristics. I found that the presence of stream flow could substantially reduce dry-season water stress in two focal tree species, but only at low levels of channel incision. Carbon isotopes in leaves from the same trees provided evidence that channel incision also causes higher levels of water stress throughout the growing season. This chronic impact of channel incision was strongly associated with differences in the riparian woody vegetation community. High levels of channel incision favored upland-associated native oak trees, while both exotic species and riparian-associated native species were more common along streams with low banks. Dry-season flow was less strongly related to community composition, but appears to be key for the establishment of riparian-associated species under drought conditions. I examined riparian soils and understory vegetation not only on top of stream banks, but also directly at the margin of the baseflow channel, a critical location for nutrient cycling in arid systems. Channel incision reduced the effects of dry-season stream flow on soil moisture in both locations, and this interaction had persistent effects on soil organic matter and perennial vegetation cover on top of stream banks. At the stream margin, channel incision was associated with a dramatic decline in soil organic matter, while dry-season flow increased the cover of perennial vegetation. This work demonstrates that urban channel incision and dry-season stream flow have persistent effects on riparian properties, both in interaction and individually. While perennial stream flow is not the historical condition in this area, my findings suggest that urban water subsidies can enhance riparian ecosystem services such as primary production and nutrient cycling, predominantly in the absence of channel incision. Urban management practices that influence the magnitude of stormflows and dry-season baseflows can thus substantially affect riparian ecosystem function.

This book was released on 2015-03-21 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers around the world are threatened by changes in land use, climate, hydrologic cycles, and biodiversity. Global changes in rivers include, but are not restricted to water flow interruptions, temperature increases, loss of hydrological connectivity, altered water residence times, changes in nutrient loads, increasing arrival of new chemicals, simplification of the physical structure of the systems, occurrence of invasive species, and biodiversity losses. All of them affect the structure and functioning of the river ecosystem, and thereby, their ecosystem services. Understanding the responses of river ecosystems and their services to global change is essential for protecting human well being in all corners of the planet. Rivers provide critical benefits by providing food from fisheries and irrigation, regulating biogeochemical balances, and enriching our aesthetic and cultural experience. Predicting responses of rivers to global change is challenged by the complexity of interactions among these man-made drivers across a mosaic of natural hydrogeomorphic and climatic settings. This book explores the broad range of determinants defining global change and their effects on river ecosystems. Authors have provided thoughtful and insightful treatments of specific topics that relate to the broader theme of global change regulation of river ecosystems.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of dissolved organic matter (DOM) has fascinated scientists and engineers for at least 60 years - from the initial efforts focused on measuring the concentrations of carbon in marine and aquatic systems, to the discovery of the role of DOM in the formation of disinfection byproducts, all the way to the new emphasis on the detailed understanding of the different functional groups and basic structural features which are the basis for the physicochemical properties of the material. After 50 years of work in the area, there are still many questions regarding DOM. The study of dissolved organic matter (DOM) has fascinated researchers in different fields of science and engineering for many decades. The impact that DOM has on a wide array of environmental processes has resulted in the development of a multidisciplinary community of researchers all focusing on using different analytical techniques and experimental design to better understand DOM. This book offers select case studies focusing on the advanced characterization of DOM in different environments and with respect to different processes. It results from the conclusion of a symposium that E. M. Thurman and I had organized for the 245th meeting of the American Chemical Society, which was held on April 7-11, 2013 in New Orleans, Louisiana.
