Rive, Rive-Grown and Burst Probability of Rolled Compressive Concrete Arch Dam
The rive, every step of the rive grown and even burst of arch dam are regarded as sequence random events. Making use of the probability theory and the achievement of elastic, elastic-plastic...

Maglev Guideway Route Alignment Parameters
Passenger comfort at high maglev vehicle speeds (110 to 134 meters per second) has significant impact on the proposed use of the existing highway and railroad rights-of-way for hosting...

The Use of Geographic Information System Technology to Compare the Environmental Impacts of Human Development on Mobile Bay, Alabama, and Galveston Bay, Texas
Geographic information systems (GIS) can synthesize information rapidly and efficiently from many different sources. GIS-generated maps, which integrate multiple information layers, can...

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...

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...
