Download or read book Quantification of Beach Profile Change written by Magnus Larson and published by . This book was released on 1988 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: An engineering numerical model is presented for simulating beach profile change in the surf zone produced by wave-induced cross-shore sand transport. It simulates the dynamics of macroscale profile change, such as growth and movement of breakpoint bars and berms. The foundation for development of the numerical model was two large wave tank experiments consisting altogether of 42 cases with different incident wave conditions, median grain size, and initial beach shape. Extensive analysis was made to define and quantify parameters describing profile change and relate these parameters to wave and sand characteristics. The model was developed using transport rate relationships inferred from profile change measured in the large wave tanks. Distributions of the net transport rate were obtained by integrating the sand conservation equation across pairs of profiles separated in time. Semi-empirical transport rate relationships were developed for different regions of the profile. The beach profile change model was calibrated and verified with the prototype-scale laboratory data. It was also applied to simulate field beach profile change measured in five storm events and good agreement was found. Beach profile evolution in the vicinity of a seawall and the adjustment of a beach fill to incident waves were also studied with the model. (edc).

Sandy Beach Morphodynamics brings together the latest research on beach systems and their morphodynamics and the ways in which they are studied in 29 chapters that review the full spectrum of beach morphodynamics. The chapters are written by leading experts in the field and provide introductory level understanding of physical processes and resulting landforms, along with more advanced discussions.
Download or read book Dune Erosion During Storm Surges written by Jacob Simon Marie van Thiel de Vries and published by IOS Press. This book was released on 2009 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because large parts of The Netherlands lie below sea level and are largely protected from flooding by a narrow strip of sandy beaches and dunes, optimal management of this coastal strip is of vital importance. This work extends the existing knowledge of dune erosion during storm surges as it occurs along the Dutch coast. Among the areas discussed are: a large scale erosion experiment designed to improve insight into near dune hydrodynamics, sediment transport and interaction between dune face and swash zone; detailed modeling to study dune erosion physics, validated against measurements, and a morphodynamic dune erosion model applied in a variety of dune erosion conditions. This publication represents a valuable contribution to an improved understanding of dune erosion, an increasingly important area of study with regard to climate change and rising sea levels.

This book was released on 1996-01-12 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many coastal communities have built structures at their beaches and added quantities of sand in contoured designs to combat erosion. Are such beach nourishment projects technically and economically sound? Or are they nothing more than building sand castles, as critics claim? Beach Nourishment and Protection provides a sound technical basis for decision-making, with recommendations regarding the utility of beach nourishment, the appropriate role of federal agencies, responsibility for cost, design methodology, and other issues. This volume: Examines the economic and social role of beaches, the history of beach nourishment projects, and management strategies for shore protection. Discusses the role of the U.S. Army Corps of Engineers and other federal agencies, with a close-up look at the federal flood insurance program. Explores the state of the art in project design and prediction of outcomes, including the controversy over the use of traditional and nontraditional shore protection devices. Addresses what is known about the environmental impacts of beach nourishment. Identifies what outcomes should be targeted for continued monitoring by project officials.

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 Nonparametric Functional Data Analysis written by Frédéric Ferraty and published by Springer Science & Business Media. This book was released on 2006-11-22 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern apparatuses allow us to collect samples of functional data, mainly curves but also images. On the other hand, nonparametric statistics produces useful tools for standard data exploration. This book links these two fields of modern statistics by explaining how functional data can be studied through parameter-free statistical ideas. At the same time it shows how functional data can be studied through parameter-free statistical ideas, and offers an original presentation of new nonparametric statistical methods for functional data analysis.

Download or read book Sand and Gravel Spits written by Giovanni Randazzo and published by Springer. This book was released on 2015-04-16 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book draws together a series of studies of spit geomorphology and temporal evolution from around the world. The volume offers some unique insights into how these landforms are examined scientifically and how we as humans impact them, offering a global perspective on spit genesis and evolution. Spits are unique natural environments whose evolution is linked to the adjacent coast and near shore morphology, sediment supply, coastal dynamics and sea-level change. Over the past century, Global Mean Sea Level (GMSL) has risen by 10 to 20 centimetres and many coastal spits represent the first sentinel against coastal submersion. Scientific research indicates that sea levels worldwide have been rising at a rate of 3.5 millimetres per year since the early 1990s, roughly twice the average speed of the preceding 80 years. This trend, linked to global warming will undoubtedly cause major changes in spit morphology. Spits are highly mobile coastal landforms that respond rapidly to environmental change. They therefore represent a signature of past environmental change and provide a landform indicator of climate change.
Download or read book Design Of Coastal Hazard Mitigation Alternatives For Rising Seas written by David Basco and published by World Scientific. This book was released on 2020-07-02 with total page 1032 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely book is about how to design alternatives to reduce coastal flood and wave damage, erosion, and loss of ecosystems facing an unknown future of sea level rise. The latest theories are interlaced with applied examples from the authors' 48 years of experience in teaching, research, and as a practicing, professional engineer in coastal engineering. The design process takes into consideration all the design constraints (scientific, engineering, economic, environmental, social/political/institutional, aesthetic, and media) to meet today's client needs, expectations, and budgets for an uncertain future.The book is organized as a textbook for graduate students. And, it is a self-contained reference for government and consulting engineers responsible for finding solutions to coastal hazards facing the world's coastal populations. New solutions are included in the book that help people of all socio-economic levels living at the coast. Both risk reduction metrics quantified in monetary terms, and increased resilience metrics quantified as vulnerability reduction must now be taken into consideration to make equitable design decisions on hazard mitigation alternatives.In the Anthropocene Era, under 'deep uncertainty' in global mean sea level predictions for the future, today's designs must mitigate today's storm damages, and be adaptable for the unpredictable water levels and storms of the future. This book includes a design 'philosophy' for water levels to year 2050 and for the long term from 2050 to 2100. Multiple spreadsheets are provided and organized to aid the design process.This is an exciting time to be 'thinkers' as Civil/Coastal engineers.Related Link(s)
Download or read book Coastal Processes Assessment for Brevard County Florida with Special Reference to Test Plaintiffs written by Nicholas C. Kraus and published by . This book was released on 1999 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report was prepared as an independent assessment of the coastal physical processes occurring along Brevard County, Florida. The study was conducted for the U.S. Department of Justice, Environment and Natural Resources Division, in its involvement with the lawsuit Applegate et al. versus the United States of America. Long-term regional beach change is evaluated by analysis of survey data on shoreline position, bathymetry, and beach profiles taken through time. In addition, analysis is specifically made for the properties of two test plaintiffs selected by the Court. Estimates of beach and dune erosion, if any, are calculated for the two test plaintiffs from date of purchase of the properties. Erosion of the beaches and dunes, principally attributed to storms, was estimated at the properties of the two test plaintiffs by compiling storm data and calculating beach and dune change with a numerical model.
