A Numerical Procedure to Compute Bearing Capacity of Shallow Foundations
A simple numerical procedure of calculation of bearing capacity of shallow foundation is proposed. This procedure employs the Terzaghi-Prandtl model of general shear failure. In this paper,...

Regional Stress Field Due to Water-Filling at Sanxia Dam
This paper uses the observed stress values to simulate the tectonic stress field in the reservoir. Based on the increment analysis method. we discuss the effects and variations of the...

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...

Fractal Dimension of Aggregated Sediments
Cohesive sediment dynamics in estuarine systems are strongly affected by particle aggregation and flocculation. These processes are mainly controlled by the Brownian motion, flow turbulence...

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...

Continuum-Mechanics-Based Rheological Formulation for Debris Flow
This paper aims to assess the validity of the generalized viscoplastic fluid (GVF) model in the light of both the classical relative-viscosity versus concentration relation and the dimensionless...

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 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...

A New Type of Concrete Trapezoid Dam
A new type of 128.0 m height concrete trapezoid dam (t-d) has been built for the Wunana Town Hydroelectric Power Station (WTHPS). The paper presents its optimum section design, several...

Serviceability Stress Limits for Composite Beams
Serviceability limits are increasingly becoming the critical design requirement for composite beams. A set of three illustrative design studies indicates that this is particularly true...

The Load Factor
Spangler's load-factor formula for projecting conduits is generalized to all cases of buried rigid pipe, whether in trenches or under embankments; this is in accordance with the analytical...
