Minimum Energy Loss and Velocity Profiles in Pipes
Minimum energy loss in a flow is discussed. The concept is applied to derive velocity distributions for laminar flow through a circular pipe and steady uniform turbulent flow through a...
Discharge and Depth Behind a Partially Breached Dam
The role that the velocity-distribution correction factor plays in the determination of the flood discharge and corresponding flow depth behind a partially breached dam is investigated....
Comparison of Some River Discharge Calculation Methods
To measure the discharge of a river, it is necessary to develop a stage-discharge curve based on water velocity at various cross sections of the river. This is the method which is used...
Depleted Uranium Migration in Stream Bedload Environment
The objective of this paper is to present results of a comprehensive hydrologic transport study, designed to assess potential surface water contamination, resulting from the release of...
Versatile Methodology for Flow Depth and Velocity Modeling in Stream Aquatic Habitat Assessment
The habitat assessment methodology developed by the IFG Instream Flow Group is a useful tool for evaluating instream flow needs. The methodology for basin flow modeling developed in this...

Laser-2-Focus Flow Measurements in the Runner of a Bulb Turbine and Comparison with Calculation
Flow measurements are presented, which were carried out near and inside the 4-blade runner of an axial model bulb turbine of double adjustable type. These measurements were performed by...
Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...
Importance of Phasing of Strong Ground Motion in the Estimation of Structural Response
In this paper, the influence on Fourier phase spectrum of seismic source directivity due to rupture propagation along the earthquake source is investigated. The phasing is described using...
Seismic Cone Penetration Test
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...
Comparison of the SPT,CPT, SV and Electrical Methods of Evaluating Earthquake Induced Liquefaction Susceptibility in Ying Kou City During the Haicheng Earthquake
The capability of SPT, CPT, Shear Wave Velocity and Electrical methods to evaluate earthquake induced liquefaction susceptibility of soil deposits consisting of sensitive clayey silts...
Seepage Studies Using Tracers and the Self Potential Test
Mill Creek Dam, a homogeneous silt structure resting on a conglomerate foundation, has experienced severe 'seepage since its construction in 1941. In 1981, a concrete cutoff...
Analysis of Liquefaction Potential by Insitu Testing
This paper describes the results of insitu testing performed to assess the liquefaction potential of a sand formation at a site for a proposed large industrial facility in East Central...
In Situ P and S Wave Velocity Measurement
A review of the in situ techniques to measure P and S wave velocities by seismic wave propagation is presented. A relatively new technique, the suspension PS logging method, is described...
Effect of the Fluid Velocity on the Biofilm Development
In order to get basic information concerning the application of a biological treatment to the ammonia nitrogen removal from drinking water, we considered the relation between the biofilm...
Strudel Scour: An Arctic Seafloor Scouring Process
Strudel scour is an arctic phenomenon which occurs every spring when the fresh-water rivers melt and inundate the sea ice cover of the arctic sea. This fresh water flowing out over the...
Use of Rayleigh Waves in Liquefaction Studies
The Spectral-Analysis-of-Surface-Waves method is a new seismic method for efficient determination of shear wave velocity in situ. Vertical impacts applied to the ground surface are used...
Seismic CPT to Measure In-Situ Shear Wave Velocity
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...
Relationships between Shear Wave Velocity and Depth of Overburden
Relationships between in-situ shear wave velocity and depth of overburden have been derived for various Quaternary age soils encountered primarily in Southern California. The geotechnical...
Is There Grit in Your Sludge?
Getting the grit out of municipal sludge can lower the total cost of operating a wastewater plant. Grit escalates maintenance costs and abrasive-laden sludge is costly to dispose of. Because...
