Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
Estimating Average Velocity in Cobble-Bed Channels
A data set obtained from natural channels having D//5//0 less than 64 mm and d/D//5//0 in the range of 3 to 20 is used as a basis for testing equations proposed by Limerinos, Thompson...
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Laboratory Study of Mud Flows
In the study reported depth profiles and tip velocities were measured for a series of unsteady mud flows generated in a laboratory flume using a dam break scenario. Observation of a wide...
Local Scour Under Waves Oblique to Current
Local scour around a cylindrical pile subjected to waves oblique to current was experimentally studied in a laboratory flume with a wave generator. The mode of wave-current interaction...
Applications of the Singular Point Method to Hydraulic Analysis of Spillways
A computer-oriented procedure is described to develop rating tables for side channel spillways. The procedure includes three sets of computations which have to be performed iteratively...
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....
Composite Resistance to Flow With an Ice Cover
Recent data collected on several rivers in Michigan suggest, with only an ice cover present, that Manning's roughness ratio is constant at n//R equals 0. 65. If other ice...
Accuracy of Computed Water Surface Profiles
Stream cross-sectional geometry obtained from aerial surveys (aerial spot elevations and topographic maps) that conform to mapping industry standards are more accurate than is often recognized....
Effects of Land Subsidence on Flood Profiles
In this study, the effects of land subsidence on water-surface elevation and depth profiles during flood conditions were investigated for a large, hypothetical, slope-controlled stream....
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...
HEC-1 and HEC-2 Applications on the Microcomputer
The Hydrologic Engineering Center (HEC) has developed versions of the HEC-1 Flood Hydrograph Package and the HEC-2 Water Surface Profiles programs for MS/PC-DOS compatible microcomputers...

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...
