# 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...*

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 μ*m

_{o}, momentum_{o},...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....*
