Shoreline Environmental History: Making it Visible with Public Art and Historic Interpreation?An Olympia, Washington Case Study
This paper briefly describes the efforts under-way to understand and celebrate Olympia, Washington's shoreline environmental history by tracking its influence on water quality, marine...
Dredging Related Sea Turtle Studies Along the Southeastern U.S.
Recent studies have documented that five threatened or endangered species of sea turtles occur along the southeastern U.S. coast and are potentially affected by hopper dredging activities....
The History of the Black Sea Coastal Zone Studies
The exploration of the Black Sea coast by Russian hydrographers began in the early 19th century. Hydrographic expeditions of Budishev (1802) and Zarudny (80-ties of the 19th century) provided...
The General Characteristic of the Black Sea Coasts
The total length of the Black Sea coast is 4431 km. These shores have been developing in various natural conditions formed through the entire history of this basin. So, the coasts may...
Waves and Currents Near the Kinburn Spit Extremity
A method of calculation of wave transformation and of currents generated by waves in a surf zone, including a spit extremity is offered. No additional hypothesis on radial stress and wave...
Sedimentational Aspects of Erdemir Port (Eregli, Turkey)
This paper reviews available information on environmental conditions, historical data on sea bed topography and dredged volumes for understanding sedimentational processes at or near the...
Geology of the Southern North Sea Basin
The southern North Sea basin has had a long and complex geological history. Between Late Carboniferous and the end of Triassic times, the basin was largely confined between two ancient...
The Shaping of the French-Belgian North Sea Coast Throughout Recent Geology and History
The present-day French-Belgian North Sea coastal barrier and coastal plain were shaped after the last Ice Age, when especially between 10,000 and 5,000 years ago the global sea level underwent...
Global Sea Level in the Past and Future Century
During the past 150 years sea level may have risen globally by, at the most, 1.1 mm/year from about 1850 to 1930-1940. There is no straightforward relation between climate and sea level....
Louisiana Cheniers: Clues to Mississippi Delta History
The cheniers of southern Louisiana have map differences, deeding differences, and granulometric differences that distinguish them from swash-built beach ridges and from dune ridges. Instead,...
Friction Factors in Coastal Flooding
As the world's coastal zones are being developed and the coastal population increases, coastal flooding, or rather the prediction of its extent and frequency of occurrence, becomes a more...
Computation of Flow Past a Cylinder Mounted on a Flat Plate
The surface shear stress distribution in the vicinity of a circular cylinder - mounted normal to a rigid flat plate - produced by the three-dimensional flow past it, is investigated numerically...
Shape Effect on Bed-Load Transport in Pipes
The nature of part-full flows in pipe sewers produces different channel shapes resulting in non-uniform shear stress distribution on the wetted perimeter. New experimental data were utilized...
Flow Resistance Properties of Flexible Linings
Flow resistance for flexible channel linings is a function of the relative roughness of the lining in accordance with boundary-layer principles. As with vegetation, flexible linings have...
Rheometry of Natural Sediment Slurries
Recent experimental analyses of natural sediment slurries yield diverse results yet exhibit broad commonality of rheological responses under a range of conditions and shear rates. Results...
Bed Shear Stress in Unsteady Open-Channel Flows
In this study, velocity distributions over smooth and rough beds were accurately measured with an LDA in unsteady open-channel flows. The log-law distributions yielded well in the wall...
Riprap Design at Bridges?Factor of Safety Approach
The factor of safety method offers a physically based methodology for design of riprap that relates the applied shear stress on the channel boundary to the stability of the riprap layer....
Riprap Incipient Motion and Shields' Parameter
Unobstructed incipient motion data from a variety of sources are compiled to re-examine current thinking regarding riprap stability. Shields' framework is investigated and relationships...
A Study on Debris Flow Surges
The mechanism of development of debris flow surges i studied theoretically and experimentally. It is proved that the development of viscous debris flow from continuous flow into a series...
Turbulent Velocity Flutuations in Natural Rivers
The longitudinal and transverse components of flow velocity, as well as the normal and tangential stresses, must be expected to fluctuate with time and space when flow at a high Reynolds...
