Sand Bed Friction Factors for Oscillatory Flows
Published data from the Carstens, Neilsen, and Altinbilek (4) oscillatory water tunnel tests are plotted as friction factor versus Reynolds number. These data, for three sand sizes and...

Radial Hydraulic Jump
Radial hydraulic jump occurs in a stilling basin with diverging side walls. Experimental data is used to obtain the free-surface profiles and the floor-pressure profiles within the diverging...

Mixing of Buoyant Surface Jet over Sloping Bottom
The mean characteristics of a buoyant surface jet discharged horizontally over sloping bottom was investigated through a set of systematic experiments. It was found that the mean characteristics...

Runoff Curve Numbers form Partial Area Watersheds
A previously observed relationship between runoff curve numbers and storm rainfall is further examined. Under some wildland conditions the runoff curve numbers have been observed to decrease...

Finite Element Model of 2-D Stratified Flow
A finite element model for the study of hydrodynamics and salt transport in partially-mixed estuaries is presented. The model is based on the laterally integrated time varying equations...

Laser-Doppler Measurements in Axisymmetric Plumes

Further Tests on Ocean Wave Forces on Sphere
Wave force coefficients have been obtained for a 28.8-in diam sphere. The work was done at a test site in 37 ft of water offshore from Honolulu. The peak flow velocities encountered during...

Wastewater Disposal from Two-Dimensional Diffuser
The purpose of this note is to present an explicit equation that gives the center line dilution in a line vertical buoyant jet for any initial Froude number....

Unified Presentation of Weir-Aeration Data
The literature on reoxygenation studies on free overall weirs has been reviewed with the main objective of investigating model scale effects. A nomogram has been presented for constant...

Dilution in a Vertical Round Buoyant Jet
A round, vertical, turbulent buoyant jet is defined here as a source of fluxes per unit mass of mass μo, momentum mo,...

Pressure Drop Due to Flow Through Fine Mesh Screens
In hydraulic models, the proper simulation of pressure drop and velocity modification behavior of the screens is important. A good estimate of the pressure losses across square mesh screens...

Developing Zone Characteristics in Aerated Flows
A knowlegde of air concentration distribution is very essential in the study of flow characteristics in the developing zone. The local mean air concentration along the flow is correlated...

Behavior Study of Curved Box Bridges
A numerical analysis of a number of single-cell curved box-girder sections with variable curvature, length, web spacing, number of diaphragms, and loading was performed. The effects of...

Predictions of Heat and Mass Transfer in Open Channels
The paper describes a three-dimensional model for calculating the distribution of velocity, temperature, and pollutant concentration in open channel flows, and a depth-averaged two-dimensional...

Experiments on Surface Buoyant Jet
An experimental investigation of a surface buoyant jet is presented. The densimetric Froude number and the Reynolds number of the discharge channel were 3.6 and 33,000, respectively. Longitudinal...

Secondary Flow in Noncircular Conduits
A requirement for calculating an accurate velocity distribution in noncircular conduits is a knowledge of the secondary flow distribution in these conduits. The cause of these secondary...

Size Determination of Partly Full Conduits
The transition from partly full to full pipe (sealing) is accompanied by vibrations of the structure and surging of the flow. The experimental study was done in a 4-in. (100-mm) square...

Horizontal Buoyant Jets in Quiescent Shallow Water
The flow behavior of a single round buoyant jet discharging into a shallow quiescent body of water is experimentally investigated. The temperature distributions are measured in a large...

Hydraulic Analysis of Model Treatment Units
Rational guidelines for designing studies to improve an existing water or wastewater treatment unit configuration through the use of experimental analysis of small-scale models are presented....
