Available in PDF, EPUB and Kindle. Book excerpt: This book represents the efforts of over a hundred individuals who planned and executed the NSTS field experiments, analyzed the billions of data points, and distilled their findings and insights into the summaries found here. Because these experiments were of a scope that will seldom, if ever, be duplicated, and because the program brought together many of the foremost field experimentalists in this country, we all felt from the beginning that it was important to preserve the outcome. This was done in two ways. First, the raw data were made available to any interested investigator within 18 months of the completion of each experiment. Secondly, both the methodology of the experiments and the findings from them were codified in the form of a monograph. This book is that result. I have had the occasion recently (Sediments '87 Proceedings, Vol. 1, pp. 642-651) to assess the NSTS performance. I found that we made giant strides in our understanding of the surf zone hydrodynamics --far more than our fondest expectations at the beginning. We were able to do less than we had hoped about the response of the sediment, largely because of a limited ability to measure it at a point. As I reported in the Sediments '87 assessment, we established a new state of the art in measurement techniques and we demonstrated the effectiveness of large, multi-investigator, instrument-intensive experiments for studying nearshore processes.

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.

This book was released on 1980 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: New dredge-disposal techniques may serve the dual role of aiding sand by-passing across coastal inlets, and beach nourishment, provided the dredged sediments placed seaward of the surf zone move shoreward into that zone. During the summer of 1976, 26,750 cubic meters of relatively coarse sediment was dredged from New River Inlet, North Carolina, moved down coast by a split-hull barge, and placed in a 215-meter coastal reach between the 2- and 4-meter depth contours. Bathymetric changes on the disposal piles and in the adjacent beach and nearshore area were studied for a 13-week period (August to November 1976) to determine the modification of the surrounding beach and nearshore profile, and the net transport direction of the disposal sediment. The sediment piles initially created a local shoal zone with minimum depths of 0.6 meter. Disposal sediment was coarser (Mn = 0.49 millimeter) than the native sand at the disposal site (Mn = 0.14 millimeter) and coarser than the composite mean grain size of the entire profile (Mn = 0.21 millimeter). Shoaling and breaking waves caused rapid erosion of the pile tops and a gradual coalescing of the piles to form a disposal bar located seaward (= 90 meters) of a naturally occurring surf zone bar. As the disposal bar relief was reduced, the disposal bar-associated breaker zone was restricted to low tide times or periods of high wave conditions.

Download or read book Mechanics of Coastal Sediment Transport written by J?rgen Freds?e and published by World Scientific. This book was released on 1992 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats the subject of sediment transport in the marine environment, covering transport of non-cohesive sediment by waves and current in- and outside the surf zone. It can be read independently, but a background in hydraulics and basic wave mechanics is required. It is intended for M.Sc. and Ph.D. students. The primary aim of the book is to describe the physical processes of sediment transport and how to represent them in mathematical models. It does not present a large number of different formulae for the sediment transport rates under various conditions. The book can be divided in two main parts; in the first, the relevant hydrodynamic theory is described; in the second, sediment transport and morphological development are treated. The hydrodynamic part contains a review of elementary theory for water waves, chapters on the turbulent wave boundary layer and the turbulent interaction between waves and currents, and finally, surf zone hydrodynamics and wave driven currents. The part on sediment transport introduces the basic concepts (critical bed shear stress, bed load, suspended load and sheet layer, near-bed concentration, effect of sloping bed); it treats suspended sediment in waves and current and in the surf zone, and current and wave-generated bed forms. Finally, the modelling of cross-shore and long-shore sediment transport is described together with the development, of coastal profiles and coastlines.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a synthesis of research findings, in terms of strategic knowledge outcomes regarding emergence of recent regional climate signals, implications for impacts assessment, and mitigation and adaptation response, relevant in the Indian context. The first part discusses evidence of climate change and its underlying scientific processes across India, chiefly focusing on impacts that are already visible and attributable to anthropogenic activities. The latter part deals with the responses to climate change, highlighting the mitigation and adaptation strategies in various sectors and communities. The book presents a concise interpretation, distilling practical recommendations and policy prescriptions at national and sub-national levels. It serves as a reference point for understanding scientific advances and persisting uncertainty, future vulnerability and response capacity of interlinked human and natural systems, pertaining to India. It is an excellent resource for policy makers and industry watchers in addition to the research fraternity.

Download or read book Sediment Transport Processes in the Nearshore Waters Adjacent to Galveston Island and Bolivar Peninsula written by Gary Lynn Hall and published by . This book was released on 1976 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: The net longshore transport of sand along Bolivar Peninsula and Galveston Island during 1975 was toward the southwest at rates that varied from 1.52 x 10 5 yds3/yr at Sea Isle on Galveston Island to 5.4 x 10 4 yds3/yr at Gilchrist on Bolivar Peninsula. Net longshore transport was toward the southwest during months of fall, winter and spring and generally toward the northeast only during three months of summer. An excellent correlation exists between the longshore transport direction and several factors including the frequency of the observed wave approach, speed and direction of the longshore current and the wind direction and velocity. Fluorescent sediment tracer studies revealed that a significant portion of the longshore transport showed a tendency to move parallel to the shoreline or offshore toward the breaker zone under most surf conditions. The seaward transport of sand in the surf zone was characteristically along paths nearly parallel to the angle of wave approach until reaching the breaker zone. Transport parallel to the shore at a significant distance shoreward of the primary breaker zone was usually attributed to entrainment in moderate- to high-velocity longshore currents, transport on the crests of bars or channelized flow in the runnels. Sediment tracer analyses conducted along the north and south jetties revealed that transport along these structures was controlled primarily by wind direction, wave action and the strength and direction of the prevailing tidal currents. Strong northerly winds create intense wave action which vigorously churns the sediments and batters the north jetty. Enhanced ebb-tidal currents transport the sandy sediments seaward along the jetty, through the small boat passage into the outer bar channel and ultimately around the seaward extremity of the jetty.

Download or read book Size-selective Sediment Transport and Cross-shore Profile Evolution in the Nearshore Zone written by Chatchawin Srisuwan and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cross-shore bathymetric evolution in the nearshore zone often leads to threatening consequences such as beach erosion and shoreline retreat that concern the coastal community. A new, comprehensive cross-shore morphodynamic model was developed that can be used to describe and predict these phenomena. The study included both physical and numerical models that were designed to focus on the influence of sediment size characteristics on the cross-shore sediment transport process. For a profile equilibrium timescale, three types of beach profiles with different sediment mixtures were simulated in a small-scale, random-wave flume laboratory using erosive, storm, and accretive wave conditions. Dynamic relationships between the sediment grain sorting and beach profile changes were found to be evident as size-graded sediment fractions tended to relocate to different energetic zones along the cross-shore profiles. Existing phase-averaged wave and circulation models were utilized together with several new intra-wave modules for predicting important hydrodynamic parameters that were validated using the experimental data. A novel, multi-size sediment transport model was formulated to compute individual transport rates of size-graded sediment fractions while accounting for their interaction and non-linear size dependencies. The model was coupled with a new grain sorting model that resolves cross-shore grain sorting and vertical grain lamination. Compared to a traditional modeling approach, the new comprehensive model proved to offer superior modeling accuracy for both profile evolution and sediment grain size change. The use of the model is most advantageous for a condition with intensive grain sorting, a common scenario on a natural beach profile. Equilibrium beach profile is also better simulated by the model as size-graded fractions are predicted to relocate to different zones where they could withstand local hydrodynamics. Other new components that also help improve the modeling capability include the terms for wave-breaking and bed-slope effects, wave-crest sediment flux, and acceleration-induced bottom-shear stress. Besides superior profile modeling accuracy, sediment size characteristics and their spatial and temporal variations are also a useful set of information provided by the new model.
