Download or read book Fluvial Remote Sensing for Science and Management written by Patrice Carbonneau and published by John Wiley & Sons. This book was released on 2012-08-15 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of progress in the general area of fluvial remote sensing with a specific focus on its potential contribution to river management. The book highlights a range of challenging issues by considering a range of spatial and temporal scales with perspectives from a variety of disciplines. The book starts with an overview of the technical progress leading to new management applications for a range of field contexts and spatial scales. Topics include colour imagery, multi-spectral and hyper-spectral imagery, video, photogrammetry and LiDAR. The book then discusses management applications such as targeted, network scale, planning, land-use change modelling at catchment scales, characterisation of channel reaches (riparian vegetation, geomorphic features) in both spatial and temporal dimensions, fish habitat assessment, flow measurement, monitoring river restoration and maintenance and, the appraisal of human perceptions of riverscapes. Key Features: • A specific focus on management applications in a period of increasing demands on managers to characterize river features and their evolution at different spatial scales • An integration across all scales of imagery with a clear discussion of both ground based and airborne images • Includes a wide-range of environmental problems • Coverage of cutting-edge technology • Contributions from leading researchers in the field

Available in PDF, EPUB and Kindle. Book excerpt: The focus of this report is technologies for fish passage around hydropower generation facilities and protection against entrainment and turbine mortality. Emphasis is given to Federal Energy Regulatory Commission (FERC)-licensed hydropower projects where fish protection is a subject of controversy and congressional interest due to the Federal Power Act (FPA) and the Electric Consumers Protection Act (ECPA). Thus institutional issues related to FERC-relicensing are also discussed. (Major points of controversy are high-lighted in box 1.1).

Download or read book An Analysis of Differential Delayed Mortality Experienced by Stream Type Chinook Salmon of the Snake River written by Nick Bouwes and published by Createspace Independent Pub. This book was released on 2012-08-23 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass transportation of juvenile fish in the lower Snake River was initiated in the late 1970's in an effort to reduce mortality of salmon and steelhead during downstream migration. Fish are transported in barges and trucks to below BON, thereby circumventing direct mortality due to passage through the hydroelectric projects and reservoirs. Measurement of the efficacy of smolt transportation has taken the form of studies of “T/C” (transport/control) ratios. These mark recapture studies measured the smolt-to-adult return rates (SARs) of test fish, which were transported, and control fish which were returned to the river. These studies estimated the relative effectiveness of transportation to improve survival rates of fish from the site where they were collected as juveniles back to (usually) the same site when they returned as adults. Included in this T/C ratio is any differential mortality from the collection point to the end of the hydrosystem (to BON tailrace), as well as any differential mortality from below BON to the adult recapture site(s). Although fish generally appear to survive reasonably well while in the trucks and barges, it is harder to gauge how well transported fish survive below BON, after they are released and continue their life cycle in the estuary and ocean. NMFS suggests there may be partial support for delaying a decision to breach the lower Snake River hydroelectric dams because 'D' estimates, using “improved methods provided by PIT-tag technology”, appears to be high for the recent past (A-Fish). Based on these estimates, NMFS further suggest that “ongoing experiments by NMFS are likely to resolve the uncertainty regarding differential delayed transportation mortality in 5 to 10 years.” Alternatively, the Plan for Analyzing and Testing Hypotheses (PATH) analyses include a larger set of T/C studies and stock recruitment data that suggests 'D' is low, which lends support to breaching of the four Snake River dams as the most robust hydro action for recovery of Snake River salmon and steelhead (Marmorek et al. 1998). In this paper, we evaluate the NMFS conclusion that 'D' is now much higher than previously thought (A-Fish), demonstrate the sensitivity of estimates of 'D' to the numerous assumptions required to make an estimate of 'D', clarify and discuss the evidence for and against various interpretations of these assumptions, and discuss the possibility of improving estimates of 'D' in the future. We note that 'D' is not a measurement. Instead, it is an indirect estimate from data and requires numerous assumptions, with many different possible interpretations. In our analysis we evaluate the effect of these different assumptions on 'D' estimates: 1) including and excluding different control and transport groups; 2) using different techniques to expand reach survival rate estimates from a shorter experimental reach to the entire migration corridor; 3) using different approaches to weight cohort reach survival rate estimates to produce seasonal estimates; 4) using different approaches to summarize experimental groups on a daily or on a weekly basis for wild fish only or wild and hatchery fish combined; and finally 5) using different approaches of pooling or averaging estimates across years. In addition, the effects of using alternative tools (passage models) to estimate reach survival rates on 'D' value estimates were evaluated.

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.
