Experiments on Arrested Saline Wedge
Experimental results are presented which show that the onset of interfacial wave breaking can be expressed by a stability parameter which is a function of the interfacial densimetric Froude...

Force on Sill of Forced Jump
The mean force on a continuous sill in a forced hydraulic jump has been measured directly by a transducer for a wide range of experimental conditions. Four sills of heights expressed as...

Turbulence Measurements in Simulated Tidal Flow
Field measurements of tidal flow have shown that there is an increase in turbulent parameters (turbulent intensity, Reynolds stress, coefficient of turbulent diffusivity, and the rate...

Three-Dimensional Wakes: Origin and Evolution
Efforts made around 1930 for establishing a theoretical model of the wake shed by axisymmetrical bluff bodies at low Reynolds numbers failed because of inadequate information concerning...

Turbulence in Helically Corrugated Pipe Flow
Results are reported of experimental measurements of friction factor, mean and turbulent velocities, and Reynolds stresses in fully developed flow through a helically corrugated pipe....

Visualization of Separation Over Sand Waves
Flow pattern and separation over dune-shaped beds have been observed by streaming birefringence. By this visual observation, qualitative measurements were carried out, and the variation...

Empirical Investigation of Curve Number Technique
The curve number runoff equation of the U.S. Department of Agriculture, Soil Conservation Service, is treated as a transformation from rainfall distribution to runoff frequency distribution....

Fall Velocity of Shells as Coastal Sediment
The fall velocity of three common types of bivalve shells has been measured in quiescent water. The results are presented in terms of the drag coefficient as a function of the Reynolds...

Scour Around Bridge Piers at High Flow Velocities
The results of laboratory experiments on scour around circular piers in cohesionless bed material at high flow velocities are presented. A special technique is used to measure scour depths....

Transitional Periodic Boundary Layer Study
The experiments indicated that this type of flow can be turbulent at a Reynolds number considerably lower than the ciritical value for transition for flow over an oscillating flat plate....

Approximate Analysis of Unsteady Laminar Flow
Computations of unsteady laminar flows in pipies usually require lengthy calculations due to the complications presented by the exact solutions. In this paper, an alternative approach...

Infiltration and Curve Numbers: Some Pragmatic and Theoretic Relationships

Curve Numbers from Watershed Data

San Francisco Ocean Outfall Port Valve Development

Application of a Consistent Vortex Scaling Law

Laboratory Simulation of Turbulent Wind Spectra
It can be shown that to achieve similarity between the wind tunnel and the atmospheric flow, it is necessary, in principle, that the Reynolds number and the Rossby numbers be the same...

Mass Transfer Verifications of Tidal Froude Models
Hydraulic models are of limited value unless they have been verified i.e., unless pertinent model and prototype parameters have been compared and found to be in agreement. If such agreement...

Booms Used for Oil Slick Control
Experiments were conducted to determine the conditions for no containment of oil by a boom, the oil-water interfacial friction coefficient and the maximum angle which a boom can be angled...

Side Weir in Rectangular Channel
The discharge characteristics of a side weir at the head of a branch channel taking off at right angles to the main channel have been investigated. Both sharp-crested and broad-crested...

Hydraulic Resistance of Artificial Strip Roughness
An experimental study of two-dimensional flow over non-uniform roughness is reported in which artificial strip roughness was employed. The roughness elements were square in cross section...
