Book excerpt: ABSTRACT: The BANCS method has become a standard for predicting streambank erosion rates within a given region, but relies on subjective estimates of root density and has not been calibrated in the Gulf of Mexico coastal plain. This thesis presents three approaches to modeling streambank erosion rates. First, standard BANCS models were calibrated. Statistical analyses show that they are not significantly correlated to erosion rates due to inadequate estimates near-bank shear stress. Modifications to this estimate improve the models significantly (R2 = 0:31). Second, a statistical modeling process was developed using physical measurements, biomass density surveys, and soil analyses. The best statistical model requires similar data collection to BANCS, but offers higher accuracy (R2 = 0:54). Finally, a unique spatially-distributed model was developed. The model was designed to utilize global remote-sensing data and a physics-based hydrodynamic model and include the major sources of spatial and temporal variability. The model reproduces measured erosion rates with a Pearson's coefficient of R = 0:55. The spatially-distributed model allows streambank erosion rate to be estimated at any location on earth where channel geometry data are available and requires little to no field data collection. The model fills a long-standing gap in the prediction of regional sediment yield.

This book was released on 2022-12-31 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Valued for its ecological richness and economic value, the U.S. Gulf of Mexico is under substantial pressure from human activities. The Deepwater Horizon platform explosion and oil spill significantly damaged Gulf ecosystems and led to the largest ecological restoration investment in history. The unprecedented number and diversity of restoration activities provide valuable information for future restoration efforts, but assessment efforts are hampered by many factors, including the need to evaluate the interaction of multiple stressors and consider long-term environmental trends such as sea level rise, increasing hurricane intensity, and rising water temperatures. This report offers a comprehensive approach to assess restoration activities beyond the project scale in the face of a changing environment. A main component of this approach is using different types of scientific evidence to develop "multiple lines of evidence" to evaluate restoration efforts at regional scales and beyond, especially for projects that may be mutually reinforcing (synergistic) or in conflict (antagonistic). Because Gulf of Mexico ecosystems cross political boundaries, increased coordination and collaboration is needed, especially to develop standardized data collection, analysis, synthesis, and reporting. With these improvements, program-level adaptive management approaches can be used more effectively to assess restoration strategies against the backdrop of long-term environmental trends.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: High-frequency, or shorter-term, changes can pose a significant threat to coastal structures and development along the Panhandle of Florida. In order to help mitigate this threat, a new erosion model, NEXTGEN, has been tested in order to evaluate the applicability of this model for prediction purposes. Historic storms have been analyzed and results have been compared with available survey data. Statistical analyses were performed on the predicted results to evaluate the accuracy of the predictions and sensitivity of the model to input variables. Overall, analysis of the results obtained from the model confirms its reasonableness in predicting hurricane effects at the +10 foot contour in causing recession.

Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. 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.

Book Synopsis Achieving Nutrient and Sediment Reduction Goals in the Chesapeake Bay by : National Research Council
Download or read book Achieving Nutrient and Sediment Reduction Goals in the Chesapeake Bay written by National Research Council and published by National Academies Press. This book was released on 2011-09-26 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chesapeake Bay is North America's largest and most biologically diverse estuary, as well as an important commercial and recreational resource. However, excessive amounts of nitrogen, phosphorus, and sediment from human activities and land development have disrupted the ecosystem, causing harmful algae blooms, degraded habitats, and diminished populations of many species of fish and shellfish. In 1983, the Chesapeake Bay Program (CBP) was established, based on a cooperative partnership among the U.S. Environmental Protection Agency (EPA), the state of Maryland, and the commonwealths of Pennsylvania and Virginia, and the District of Columbia, to address the extent, complexity, and sources of pollutants entering the Bay. In 2008, the CBP launched a series of initiatives to increase the transparency of the program and heighten its accountability and in 2009 an executive order injected new energy into the restoration. In addition, as part of the effect to improve the pace of progress and increase accountability in the Bay restoration, a two-year milestone strategy was introduced aimed at reducing overall pollution in the Bay by focusing on incremental, short-term commitments from each of the Bay jurisdictions. The National Research Council (NRC) established the Committee on the Evaluation of Chesapeake Bay Program Implementation for Nutrient Reduction in Improve Water Quality in 2009 in response to a request from the EPA. The committee was charged to assess the framework used by the states and the CBP for tracking nutrient and sediment control practices that are implemented in the Chesapeake Bay watershed and to evaluate the two-year milestone strategy. The committee was also to assess existing adaptive management strategies and to recommend improvements that could help CBP to meet its nutrient and sediment reduction goals. The committee did not attempt to identify every possible strategy that could be implemented but instead focused on approaches that are not being implemented to their full potential or that may have substantial, unrealized potential in the Bay watershed. Because many of these strategies have policy or societal implications that could not be fully evaluated by the committee, the strategies are not prioritized but are offered to encourage further consideration and exploration among the CBP partners and stakeholders.
