Available in PDF, EPUB and Kindle. Book excerpt: KDOT occasionally finds it necessary to realign short reaches of small streams in connection with highway improvements or to protect the highway embankment against stream encroachment. A realigned stream reach should be stable and should resemble a natural stream in its cross section, profile and planform. The Kansas Analytical Method of natural stream design, developed in this report, follows the general approach recommended by the USACE and the NRCS, and incorporates hydrologic and geomorphic data from natural streams in Kansas. The realigned reach is designed to convey the same bankfull discharge and sediment load as a stable reach directly upstream. The channel length, slope, and cross-sectional dimensions are obtained from an analytical solution to Manning's equation for uniform flow and a simplified version of the Meyer-Peter and Muller sediment-transport equation, along with hydraulic-geometry relations for the bankfull width. A meandering planform with the computed length and an appropriate meander wavelength is constructed of circular arcs and line segments. A saw-tooth bottom profile with riffles and pools at appropriate locations is recommended to provide aquatic habitat during periods of little or no flow. Step-by-step instructions for stream realignment design by the Kansas Analytical Method are provided. An example illustrates the practical application of the method.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents a natural channel design method based on a reference reach approach. This method is termed the Analytical Reference Reach (ARR) method because certain characteristics and features of the design reach are copied or scaled from a reference reach and other characteristics are obtained from analytical relations. The ARR design method offers several advantages over both the Rosgen reference reach method and the analytical approach advocated by the U.S. Army Corp of Engineers and the Natural Resources Conservation Service. Its main advantage over the analytical methods is that the reference reach provides guidance for design of channel features such as meander bends and pools that cannot be designed analytically. Its main advantage over the Rosgen design method is that the channel cross-section is sized analytically to convey an appropriate bankfull discharge, and also the associated bed-sediment load if the channel is alluvial. In the ARR method, several important geomorphic characteristics of the reference reach are preserved in the design reach. These characteristics include the sinuosity of the reach, the ratio of average meander wavelength to bankfull width, and the ratio of pool depth to riffle depth. Applying the sinuosity of the reference reach to the design reach fixes the length and average slope of the design reach. The bankfull discharge for the design reach is obtained either from a hydraulic analysis of a nearby stable reach on the same stream or from a regression equation that relates bankfull discharge to watershed characteristics. Alluvial and threshold channels are sized differently. The design method for alluvial channels equates the bankfull bed-load transport capacities of the design reach and a nearby stable reach on the same stream. The design method for threshold channels scales the cross-sectional dimensions of the reference reach so that the design reach has the desired bankfull capacity. If the computed bankfull velocity exceeds the threshold value, the channel is re-designed using a different reference reach with a higher sinuosity. The ARR design method and the Kansas Analytical Method (K-TRAN Report KU-08-2) are both valid methods for stream realignment design in Kansas. Both methods should yield satisfactory designs for streams with beds composed mainly of sand, gravel or cobble. The ARR design method is preferable to the Kansas Analytical Method for silt- and clay-bed streams. This report provides guidance for reference reach selection and step-by-step instructions for stream realignment design. The Appendix to this report provides essential geomorphic and hydrologic data for 123 potential reference reaches in Kansas. Most of these data were drawn from two previous studies of Kansas streams. Our integrated data set is termed the Kansas Reference Reach Data Set (KRRDS).

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book excerpt: New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.

Download or read book Stream Restoration in Dynamic Fluvial Systems written by Andrew Simon and published by John Wiley & Sons. This book was released on 2013-05-08 with total page 939 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 194. Stream Restoration in Dynamic Fluvial Systems: Scientific Approaches, Analyses, and Tools brings together leading contributors in stream restoration science to provide comprehensive consideration of process-based approaches, tools, and applications of techniques useful for the implementation of sustainable restoration strategies. Stream restoration is a catchall term for modifications to streams and adjacent riparian zones undertaken to improve geomorphic and/or ecologic function, structure, and integrity of river corridors, and it has become a multibillion dollar industry. A vigorous debate currently exists in research and professional communities regarding the approaches, applications, and tools most effective in designing, implementing, and assessing stream restoration strategies given a multitude of goals, objectives, stakeholders, and boundary conditions. More importantly, stream restoration as a research-oriented academic discipline is, at present, lagging stream restoration as a rapidly evolving, practitioner-centric endeavor. The volume addresses these main areas: concepts in stream restoration, river mechanics and the use of hydraulic structures, modeling in restoration design, ecology, ecologic indices, and habitat, geomorphic approaches to stream and watershed management, and sediment considerations in stream restoration. Stream Restoration in Dynamic Fluvial Systems will appeal to scholars, professionals, and government agency and institute researchers involved in examining river flow processes, river channel changes and improvements, watershed processes, and landscape systematics.
