Book excerpt: The work presented herein examines how and to what extent turbidity, channel bed movement and stream source water ratios change over different temporal scales in four forested mountain headwater catchments in the Sierra Nevada, California. This work focuses on the water quality topics of sediment and source waters as part of a larger study on the effects of forest fuels treatments. No effects on water quality were expected because treatments were set far back from the stream channel and relatively light (8.0% and 7.5% decrease in mean Leaf Area Index (LAI) for the northern and southern site respectively). Therefore, this work was designed to characterize sediment and source waters rather than explore treatment impacts. In doing so important insights were gained around sediment and stream water sources. Sediment movement was found to be highly episodic and tied to low-frequency, short-duration discharge events with pronounced seasonality. Turbidity hysteresis patterns indicated localized (bed and banks) sediment sources that were mobilized quickly but became progressively depleted. Continuous measurement of channel bed elevations in the thalweg pointed to seasonal mobilization (connectedness) of sediment during winter, a gradual depletion through spring and early summer, and disconnectedness in low flow season when material builds up again at the base of banks mirroring patterns seen in the turbidity hysteresis loops. Stream water chemistry data showed higher concentrations during base flow, which was exacerbated by consecutive years of drought. The high base flow ion concentrations were tied to high ratios of groundwater. End-member mixing analysis showed that wet and dry years had similar source water ratios during high flow (winter and spring) but during the low flow season (late summer), a shift toward higher ratios of groundwater was seen for drought years. Recent tree mortality observed across the Sierra Nevada after four consecutive years of drought underscores the critical role of groundwater in maintaining baseflow and sustaining forest ecosystems. Better understanding of sediment processes, source water contributions, and drought effects in small, forested, mountain, headwater catchments provides an important foundation for sustainable land use management, more effective channel restoration design, and improved mitigation of downstream water quality.

Book excerpt: Research on reservoir sedimentation in recent years has been aimed mainly at water resources projects in developing countries. These countries, especially in Africa, often have to cope with long droughts, flash floods and severe erosion problems. Large reservoir capacities are required to capture water provided by flash floods so as to ensure the supply of water in periods of drought. The problem arising however is that these floods, due to their tremendous stream power, carry enormous volumes of sediment which, due to the size of reservoirs, are virtually deposited in toto in the reservoir basin, leading to fast deterioration of a costly investment. Accurate forecasting of reservoir behaviour is therefore of the utmost importance.This book fills a gap in current literature by providing in one volume comprehensive coverage of techniques required to practically investigate the effects sediment deposition in reservoirs has on the viability of water resources projects. Current techniques for practically estimating sediment yield from catchments, estimating the volume of sediment expected to deposit in reservoirs, predicting sediment distribution and calculating scour downstream of reservoirs are evaluated and presented. The liberal use of diagrams and graphs to explain the various techniques enhances understanding and makes practical application simple. A major feature of the book is the application of stream power theory to explain the process of reservoir sedimentation and to develop four new methods for predicting sediment distribution in reservoirs.The book is primarily directed at practising engineers involved in the planning and design of water resources projects and at post-graduate students interested in this field of study.

Book excerpt: Sediment Cascades: An Integrated Approach provides a comprehensive overview that addresses the transport of sediment through the landscape. Suitable for academic researchers, industry practitioners, research students and advanced level undergraduates, seeking detailed knowledge and an up-to-date review of the recent research literature. The emphasis is on contemporary sediment system dynamics with relevance both to landscape management and landform development. Sediment Cascades: An Integrated Approach begins with an explanation of the need for an integrated approach to sediment delivery systems and introduces the main themes of sediment production, delivery, storage and transfer. Further chapters then focus on specific environments from mountains, through floodplains, to estuaries and the continental shelf. Focuses on contemporary sediment system dynamics and current research Covers a sequence of environments from steep mountains to the continental shelf Highlights the continuity of the subject by linking each component area with its adjacent elements

This book was released on 2013-04-17 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on sediments as a pollutant in natural freshwater and marine habitats, and as a vector for the transfer of chemicals such as nutrients and contaminants. Sediment-water research is carried out all over the world within a variety of disciplines. The selected papers cover three main topics relating to assessment and/or restoration of disturbed watersheds, sediment-water linkages in terrestrial and aquatic environments and evaluation of sediment and ecological changes in marine and freshwater habitats. Innovative research in both developed and less developed countries is included. Both fundamental research, insight into applied research and system management are covered. The volume will also appeal to readers involved in sediment geochemistry and dynamics, aquatic habitats, water quality, aquatic ecology, river morphology, restoration techniques and catchment management.
