Available in PDF, EPUB and Kindle. Book excerpt: In the temperature zones of the world the formation of ice in streams and rivers may have significant effects on their water depths and velocities, even when the stream discharge does not change. Velocity and water depth are among the attributes that constitute the habitat of the aquatic species that reside in the streams and rivers. Thus, to evaluate the habitat it is important to be able to characterize the effects of ice on velocity and depth. In this report I summarize the effects of river ice on hydraulic behavior, with examples meant to provide guidance in evaluating what habitats may be expected in winter comparison with non-ice conditions of the same stream. While river ice formations may be complex at the small scale of tens of meters or less, on a larger scale they are often sufficiently uniform to enable reasonable comparisons of depth and velocities with and without ice present. The emphasis here is on shallow rivers, such as the Platte River in Nebraska. The Platte is subjected to many competing demands for its flow, among which are the demands for habitat. A concern for the required winter flows was the motivation for this study. (jes).

Download or read book Ecohydraulics written by Ian Maddock and published by John Wiley & Sons. This book was released on 2013-07-01 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecohydraulics: An Integrated Approachprovides a research level text which highlights recent developments of this emerging and expanding field. With a focus on interdisciplinary research the text examines:- the evolution and scope of ecohydraulics interactions between hydraulics, hydrology, fluvial geomorphology and aquatic ecology the application of habitat modelling in ecohydraulic studies state of the art methodological developments and approaches detailed case studies including fish passage design and the management of environmental flow regimes research needs and the future of ecohydraulics research The contributions offer broad geographic coverage to encapsulate the wide range of approaches, case studies and methods used to conduct ecohydraulics research. The book considers a range of spatial and temporal scales of relevance and aquatic organisms ranging from algae and macrophytes to macroinvertebrates and fish. River management and restoration are also considered in detail, making this volume of direct relevance to those concerned with cutting edge research and its application for water resource management. Aimed at academics and postgraduate researchers in departments of physical geography, earth sciences, environmental science, environmental management, civil engineering, biology, zoology, botany and ecology; Ecohydraulics: An Integrated Approach will be of direct relevance to academics, researchers and professionals working in environmental research organisations, national agencies and consultancies.

Download or read book Alternatives in Regulated River Management written by James A. Gore and published by CRC Press. This book was released on 2018-01-18 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers and managers of regulated river systems will find this volume useful in acquiring information for deciding an integrated management plan for regulated river operations. Rather than the ecological theory of impacts of flow regulation, emphasis has been placed on methods to predict water quality and habitat alterations, as well as techniques to mitigate impacts from various operational scenarios. Although most chapters refer to impacts of riverine impoundments, these alternatives apply to any regulated situation in which changes in water quality or flow pattern occur. The predictive modeling techniques are explained primarily from a theoretical background. However, extensive bibliographies can guide the uninitiated to specific texts and software. Where controversial techniques have been presented, alternate methods are also described. Major topic areas include water quality problems, channel modification and management, ecological modeling and management, as well as a section on perspectives for ecological management and special problems in developing nations.
