This book was released on 2011 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis aims to develop a conceptual understanding of the flooding patterns and vegetation response of large floodplain wetlands, and to apply this knowledge to develop an innundation and vegetation response model for water management. Applicable to a range of floodplain wetland systems, the conceptual node-network approach was developed in relation to the Gwydir wetlands, NSW, Australia. The Gwydir floodplains and wetlands occur in a dryland setting and are reliant on flows from the upstream catchment that has substantial water resource development. The Gwydir wetlands include a range of ecological values and are listed under international agreements for the protection of wetlands and migratory waterbirds.

Download or read book The Central Amazon Floodplain written by Wolfgang J. Junk and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floodplains are ecosystems which are driven by periodic inundation and oscillation between terrestrial and aquatic phases. An understanding of such pulsing systems is only possible by studying both phases and linking the results into an integrated overview. This book presents the results of a 15-year study of the structure and function of one of the largest tropical floodplains, the Amazon River floodplain. It covers qualitative aspects, e.g., adaptations of aquatic and terrestrial organisms to the flood pulse as well as quantitative aspects, e.g., studies of biomass, primary production, decomposition, and nutrient cycles. The authors interpret their findings and the most important data from other studies under an integrating scientific concept, the Flood Pulse Concept.

Available in PDF, EPUB and Kindle. Book excerpt: Wetlands are among the most important and complex ecosystems in the world. They contribute to nutrient cycling, the hydrologic cycle, and provide critical habitat for many plants, fish, and wildlife. Channelization of Missouri River resulted in the loss of many floodplain wetlands. Despite ongoing restoration efforts, there are few ecologically-based performance guidelines, and managers need methods to quantify and assess the success of restored riverine wetland systems. In 2008 a multi-institutional herpetofauna monitoring project, funded by the U.S. Army Corps of Engineers, was initiated in four states (Kansas, Missouri, Iowa, and Nebraska). The main goal of the project is to assess the success of previously restored wetlands and to create wetland restoration guidelines for future use. Amphibians were chosen for monitoring because they are globally declining, they integrate terrestrial and aquatic environments, and because they are good indicators of wetland restoration success. Frog call surveys and tadpole dip net surveys were conducted and analyzed using occupancy techniques to help determine restoration success. This thesis reports the results of herpetofauna monitoring from three Missouri River bends in Nebraska, a subset of the overall project. I conducted a comparison of frog call surveys and tadpole dip net occupancy results, a novel co-occurrence analysis for frog call surveys, and a functional connectivity analysis based on anuran dispersal distances. The results of the frog call surveys and tadpole dip net surveys differed in many ways. The data from the tadpole dip net surveys produced fewer results, but these results were more accurate because of their link to reproduction and the lack of spurious data. If only one method is used it should be the tadpole dip net surveys, but if the surveys are conducted in a drought year it is possible there will be insufficient data to conduct an occupancy analysis. Therefore, conducting both methods is the best way to produce the most accurate wetland restoration guidelines. The co-occurring species analysis of the frog call surveys was both more efficient and also produced a definition of wetland success for multiple species without the variation between species seen in the single species models. The functional connectivity analysis added a complex systems component to the wetland restoration guidelines, but also provided a method that can help focus management by identifying wetlands within and across complexes that are most important to functional connectivity. Combining the information gained from all of the analysis, it was determined that a successful flood plains wetland has aquatic vegetation, a shallow slope (less that 0.30), is ephemeral, has at least one wetland within 500 m, and is part of a compact (non-linear) wetland complex that has other successful wetlands and deeper, larger, less ideal wetlands that are all close enough to one another that habitat is provided in extreme conditions.

Download or read book Nature Based Flood Risk Management on Private Land written by Thomas Hartmann and published by Springer Nature. This book was released on 2019-08-22 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book addresses the various disciplinary aspects of nature-based solutions in flood risk management on private land. In recent decades, water management has been moving towards nature-based solutions. These are assumed to be much more multi-purpose than traditional “grey infrastructures” and seem to be regarded as a panacea for many environmental issues. At the same time, such measures require more – and mostly privately owned – land and more diverse stakeholder involvement than traditional (grey) engineering approaches. They also present challenges related to different disciplines. Nature-based solutions for flood risk management not only require technical expertise, but also call for interdisciplinary insights from land-use planning, economics, property rights, sociology, landscape planning, ecology, hydrology, agriculture and other disciplines to address the challenges of implementing them. Ultimately, nature-based flood risk management is a multi-disciplinary endeavor. Featuring numerous case studies of nature-based flood risk management accompanied by commentaries, this book presents brief academic reflections from two different disciplinary perspectives that critically highlight which specific aspects are of significance, and as such, underscore the multi-disciplinary nature of the challenges faced.

This book was released on 2000-10-20 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing flood damage is a complex task that requires multidisciplinary understanding of the earth sciences and civil engineering. In addressing this task the U.S. Army Corps of Engineers employs its expertise in hydrology, hydraulics, and geotechnical and structural engineering. Dams, levees, and other river-training works must be sized to local conditions; geotechnical theories and applications help ensure that structures will safely withstand potential hydraulic and seismic forces; and economic considerations must be balanced to ensure that reductions in flood damages are proportionate with project costs and associated impacts on social, economic, and environmental values. A new National Research Council report, Risk Analysis and Uncertainty in Flood Damage Reduction Studies, reviews the Corps of Engineers' risk-based techniques in its flood damage reduction studies and makes recommendations for improving these techniques. Areas in which the Corps has made good progress are noted, and several steps that could improve the Corps' risk-based techniques in engineering and economics applications for flood damage reduction are identified. The report also includes recommendations for improving the federal levee certification program, for broadening the scope of flood damage reduction planning, and for improving communication of risk-based concepts.

Book excerpt: Two Executive Orders (E.O.) issued in 1977, Floodplain Management (E.O. 11988) and Protection of Wetlands (E.O. 11990), require that Federal agencies examine the impacts of proposed actions on floodplains and wetlands. To comply with these Orders, the US Department of Energy (DOE) promulgated 10 CFR 1022, DOE Regulations for Compliance with Floodplain/Wetlands Environmental Review Requirements. DOE's floodplain/wetlands review consists of two procedures: the floodplain/wetlands determination, and the floodplain/wetlands assessment. The floodplain/wetlands determination ascertains the applicability of DOE's floodplain management and wetlands protection requirements for a proposed action. If DOE's requirements apply to a proposed action, DOE shall prepare a floodplain/wetlands assessment. The floodplain/wetlands assessment ascertains an action's impact, any alternatives, and mitigation, if appropriate. The assessment consists of a project description, an analysis of the potential impacts, and a consideration of alternatives to the proposed action. This paper describes the components of the DOE floodplain/wetlands review process.

Book excerpt: Floods cause billions of dollars in property damages each year in the United States. While programs like flood insurance and disaster relief help to lessen the burden on those harmed, they do nothing to mitigate the severity of floods. Wetlands have a natural ability to mitigate the impacts of flooding through the slowing of runoff and absorption of excess rainwater. For this purpose they are inherently valuable. This study implements a hedonic analysis to study the complicated interactions between property values, wetlands, and flood risk using detailed property transaction data in the Hudson River Valley of New York State. We augment this analysis with GIS data including FEMA flood risk maps, the location of wetlands and other land uses, and various geographic layers. We find, as expected, that higher levels of flood risk, as well as the realization of actual flooding events, negatively impact property values. We also find that the presence of wetlands mitigates the negative effect of floods to properties in flood zones, which is likely due to a reduced severity of damages. The magnitudes of these effects suggest that wetlands provide considerable benefits to property owners and the results provide a partial benefit measure for policymakers, especially to state and federal programs, such as the USDA's wetlands and conservation reserve programs whose primary aim is to preserve and restore these natural buffers.
