A laboratory experiment on sand bar migration with comparisons to recent models

Creator:: Magalen, Jason
Abstract:: Successful prediction of nearshore sediment migration is important in determining the vulnerability of a coastline. During energetic wave climates (storm events) sediment rapidly erodes from beaches and is deposited offshore. In subsequent milder wave conditions, the sediment migrates shoreward, accreting on the beach and helping to protect the coastline. It...

Analysis of rip current embayments on the Oregon coast

Creator:: Dalon, Matthew M.
Abstract:: Understanding the past, present, and future behavior of our nation's shorelines is vital for sensible coastal management. Localized areas of erosion, termed "erosional hot spots", can shift the shoreline landward threatening coastal infrastructure (Kraus and Galgano, 2001; Stauble and Gravens, 2004; McNinch, 2004). One specific type of erosional hot spot...

Dune erosion models and swash zone kinematics from remote video observations

Creator:: Palmsten, Margaret L.
Abstract:: The subaerial beach, composed of sand dunes and the foreshore, provides a natural buffer zone between vulnerable land and the dissipation of storm wave energy due to wave breaking. The natural beauty of this region is attractive to people, and as a result, significant investment has been placed in this...

Coastal hazards and community exposure in a changing climate : the development of probabilistic coastal change hazard zones

Creator:: Baron, Heather M.
Abstract:: Documented trends in rising sea levels, storminess, and extreme wave heights have the potential to increase the frequency and magnitude of coastal change hazards, increasing risks to coastal infrastructure and environmental resources. Coastal planners and decision makers need information about the impacts of future hazards in order to apply mitigation...

Tsunami-induced Soil Instability

Creator:: Fischer, Rachael Marie
Abstract:: Recent tsunami field surveys from the 2011 Great East Japan Earthquake and Tsunami have recorded numerous examples of tsunami-induced soil instability: significant scour around foundations, foundation failure of piles, and other damage caused by liquefaction. From the observations of soil instability leading to the failure of critical coastal structures, it...

Coastal sand dunes in the U.S. Pacific Northwest : regional variability in foredune geomorphology and associated physical vulnerability to hazards

Creator:: Mull, Jeremy M.
Abstract:: Coastal foredunes protect lives, infrastructure, and ecosystems during severe winter storms. In the U.S. Pacific Northwest (PNW), coastal foredune geomorphology is determined by both physical and ecological mechanisms. Before the 1900's, the native plant Elymus mollis was the dominant dune grass and dune morphology was largely determined by sediment supply...

A free boundary value problem modeling streambed erosion

Creator:: Helfenstein, Franz Hugo
Abstract:: Our purpose is twofold, to derive a 2-dimensional model of streambed erosion and to develop a solution procedure to solve the equations of our model. The flow domain, which varies in time, is bounded above by a free surface and is bounded below by an erodable streambed. An initial flow...

Simulating extreme total water levels using a time-dependent, extreme value approach

Creator:: Serafin, Katherine A.
Abstract:: Coastal flood hazard zones and the design of coastal defenses are often devised using either the maximum recorded total water level (TWL) or a 'design' event such as the 100-year return-level flood, usually projected from observed extreme events. Despite technological advances driving more consistent instrumental records of wave heights and...

Infiltration of water and its effects on soil erosion : a computational analysis pertaining to central Tunisia

Creator:: Tobbi, Belgacem
Abstract:: The purpose of this study was to use computer analysis of soil and rainfall data to predict the possible occurrence of soil erosion in Central Tunisia. Analysis was done with the program OR-NATURE (M.Ungs et al, 1985) . Central Tunisia was subdivided into northern, central, and southern subzones. Data about...

A conceptual model of soil mass movement, surface soil erosion, and stream channel erosion processes

Creator:: Swanson, Frederick J. (Frederick John), 1943-, Swanston, Douglas N., Dyrness, C. T., Cromack, Kermit, Fredriksen, R. L., Moore, Duane G., Glenn, Leslie Fred, 1944-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: The conceptual framework of an erosion model has been designed to link processes of mass wasting, surface erosion, and channel storage and transport. A program to stimulate mass wasting will be based on a variation of the factor of safety approach which balances forces tending to drive mass movement against...
