This book was released on 2012-12-06 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tide gauges show that global sea level has risen about 7 inches during the 20th century, and recent satellite data show that the rate of sea-level rise is accelerating. As Earth warms, sea levels are rising mainly because ocean water expands as it warms; and water from melting glaciers and ice sheets is flowing into the ocean. Sea-level rise poses enormous risks to the valuable infrastructure, development, and wetlands that line much of the 1,600 mile shoreline of California, Oregon, and Washington. As those states seek to incorporate projections of sea-level rise into coastal planning, they asked the National Research Council to make independent projections of sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account regional factors that affect sea level. Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future explains that sea level along the U.S. west coast is affected by a number of factors. These include: climate patterns such as the El Niño, effects from the melting of modern and ancient ice sheets, and geologic processes, such as plate tectonics. Regional projections for California, Oregon, and Washington show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections. However, projections are lower north of Cape Mendocino because the land is being pushed upward as the ocean plate moves under the continental plate along the Cascadia Subduction Zone. However, an earthquake magnitude 8 or larger, which occurs in the region every few hundred to 1,000 years, would cause the land to drop and sea level to suddenly rise.

Available in PDF, EPUB and Kindle. Book excerpt: Current sea level rise is due significantly to global warming, which will increase sea level over the coming century and longer periods. Increasing temperatures result in sea level rise by the thermal expansion of water and through the addition of water to the oceans from the melting of continental ice sheets. Values for predicted sea level rise over the course of this century typically range from 90 to 880 mm. This book presents research data on sea level rise, coastal engineering, shorelines and tides, including the tides and topography of the Strait of Gibraltar; tidal energy use for the future and sea level variation along the Estonian coast of the Baltic Sea. Also discussed herein is the potential impacts of sea-level rise on the Atlantic and Gulf of Mexico coasts and coastal management of shorelines in Colombia, South America.

Download or read book Tides Surges and Mean Sea Level written by D. T. Pugh and published by . This book was released on 1987-12-28 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present modern tidal ideas to those who are not tidal specialists, but for whom some knowledge of tides is involved in their professional or scientific field. These include hydrographers, marine and coastal engineers, geologists who specialize in beach or marine sedimentation processes, and biologists concerned with the ways in which living organisms adapt to the rhythms of the sea. Modern practical studies are concerned with problems of marine transport, coastal erosion and the design of coastal defences against flooding. Interest in mean sea-level changes has recently been focused on the possibility of significant increases over the coming century as a result of global warming. Examples of applications from North America, Europe and other parts of the world are included.

This book was released on 2011-01-10 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.

Available in PDF, EPUB and Kindle. Book excerpt: In June 2015 we held a workshop on the beautiful island of Mallorca, Spain with a focus on sea level variability and change. Over 120 sea level experts from around the world attended this workshop, from a range of different disciplines. The main aims of the workshop were to: 1.) Evaluate the current state-of-knowledge of sea level science; 2.) Identify gaps and unresolved questions in any aspect of sea level science; and 3.) Design future research to address these issue. All aspects of sea level changes were covered, from global to regional, observations and modelling, processes driving mean sea level changes and extremes, from the geological scale to the instrumental era and future projections and including impacts on the coastal zones. This E-Book presents papers that came out of that workshop. Overall, these papers illustrate the multi-disciplinary nature of sea level research, cross-cutting many fields of research including: oceanography, meteorology, geology, coastal morphodynamics, engineering and the social-economic aspects. Collectively, theses articles represent an interesting range of perspectives and original studies that contribute to understanding the dynamic nature of sea level and its impacts across a wide range of time and space scales.

Download or read book Mitigating Shore Erosion Along Sheltered Coasts written by National Research Council and published by National Academies Press. This book was released on 2007-05-04 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like ocean beaches, sheltered coastal areas experience land loss from erosion and sea level rise. In response, property owners often install hard structures such as bulkheads as a way to prevent further erosion, but these structures cause changes in the coastal environment that alter landscapes, reduce public access and recreational opportunities, diminish natural habitats, and harm species that depend on these habitats for shelter and food. Mitigating Shore Erosion Along Sheltered Coasts recommends coastal planning efforts and permitting policies to encourage landowners to use erosion control alternatives that help retain the natural features of coastal shorelines.

Download or read book Sea Level Rise and Coastal Subsidence Causes Consequences and Strategies written by J.D. Milliman and published by Springer Science & Business Media. This book was released on 1996-02-29 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse-induced climate warming increasingly appears to be a reality, and the warming climate will be accompanied by an accelerated sea level rise - as much as 60-100 cm over the next century. What is commonly absent in the discussion of rising sea level, however, is the role played by the subsidence of low-lying coastal areas, which can have a far greater local effect than the eustatic rise of the sea. The combined sea-level rise and land subsidence will almost certainly make the greatest impact on coastal societies in the densely populated regions of southern Asia, but its effects will be felt globally. This volume explores the concepts of sea-level rise and coastal subsidence, both natural and anthropogenically accelerated, in the form of a series of case studies in such diverse locations as Bangkok, Bangladesh, Venice, and the Niger and Mississippi deltas, as well as a discussion of the economic, engineering and policy responses that must be considered if the effects of local sea-level rise are to be mitigated.

Download or read book Sea Level Variations of the United States 1854 1999 written by Chris Zervas and published by . This book was released on 2001 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this report, monthly mean sea level (MSL) variations are analyzed for 117 stations of the National Ocean Service's (NOS) National Water Level Observation Network (NWLON) having between 25 and 146 years of data. Monthly MSL data up to the end of 1999 are used to calculate linear trends, and to obtain the average seasonal cycle, the residual time series, and the autoregressive coefficient of the residual with accurate estimates of standard errors. Months with extreme high or low residuals are defined and periods of broad regional correlations between station anomalies are observed. Since the derived trends include the local vertical land motion, they are spatially variable. Calculated MSL trends range from 9.85 mm/yr for Grand Isle, LA to -16.68 mm/yr for Skagway, AK and are consistent with previous station trends published by NOS. The appendices of this report include time series plots for each station of the monthly MSL with the seasonal cycle removed, the seasonal cycle, and the MSL residual after both the seasonal cycle and the trend are removed. The location and timing of any major earthquakes near stations in tectonically-active areas are noted, since an associated vertical offset or a change in MSL trend is possible. An inverse power relationship is derived empirically, relating the standard error for linear trends to the year range of MSL data. An estimated 50 to 60 years of data are required for obtaining linear MSL trends having a 1 mm/yr precision with a 95% statistical confidence interval. For a given length of data, the standard errors for trends at Pacific Ocean and western Gulf of Mexico stations tend to be greater than standard errors for trends at Atlantic coastal stations. MSL trends for the most recent 50-year period of 1950-1999 are compared with trends obtained from each station's entire data set. The trend for the past 50 years is significantly lower at only three out of sixty stations (Eastport, Portland, and Boston). At no station is the 1950-1999 trend significantly higher than the trend obtained from the station's entire data set. In an examination of 50-year MSL trends at sixteen of the longest term stations, it was found that for six Atlantic stations, the periods centered on years from 1930 to 1955 tend to have significantly higher trends than periods centered on years from 1965 to 1975. For San Francisco, trends for all 50-year periods centered from 1890 to 1915 are significantly lower than the overall trend and the trend since the 1906 San Francisco earthquake"--Executive Summary.

Download or read book Modelling Morphological Response of Large Tidal Inlet Systems to Sea Level Rise written by Pushpa Kumara Dissanayake and published by CRC Press. This book was released on 2011-12-16 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this work qualitatively investigates the morphodynamic response of a large tidal inlet/basin system to future relative sea level rise (RSLR) using the state-of-the-art Delft3D numerical model. Understanding the potential impacts of RSLR on these systems is a prerequisite for their sustainable management due to their rich bio-diversity and the increase in economic activities and local communities in recent decades. The adopted approach used a highly schematised model domain analogous to the Ameland inlet in the Dutch Wadden Sea. Model simulations were undertaken applying tidal and wave boundary forcings with three IPCC projected RSLR scenarios (no RSLR, low RSLR and high RSLR). Predicted inlet evolution indicated a channel/shoal pattern typically observed at the Ameland inlet. RSLR enhances the existing flood-dominance of the system leading to erosion on the ebb-tidal delta and accretion in the basin. Under the no RSLR case, resulting bed evolution of the process-based model (Delft3D) tends to agree with empirical-equilibrium relations of the ASMITA model. Application of the low RSLR scenario resulted in quite stable tidal flat evolution. Model simulations with the high RSLR scenario indicated disappearing the tidal flats over time and turning the system into a lagoon. Applying nourishment hardly compensated the RSLR induced sediment demand of tidal flat evolution.
