Effect of Temperature on Settling of Fine Sediments
Results from settling experiments in an annular flume using kaolinite clay in distilled water are presented. Identical experiments carried out at different temperatures show that as temperature...
Characteristic Deformation of Alternate Bars Due to Low Flow
Experiments on the formation of a small meander-channel at low stage are conducted by supplying a proper discharge on initial bed of alternate bars that have been formed in experimental...
Flow Transitions Around a Single Large Bed Element
A qualitative description of the characteristics of supercritical-to-subcritical flow transitions due to the presence of a single large bed element (LBE) in a laboratory flume is presented....
Momentum and Kinetic Energy Coefficient Research?Ramp Flumes
In October 1984. Reclamation Hydraulic Branch staff members investigated the operation of the A-Canal ramp at Klamath Falls, Oregon. The ramp flume was completed in 1983 as a water measurement...
Limitation to Standard Parshall Flume Calibrations
Parshall flumes are widely used for metering open channel flows. An inspection of the original study which developed the rating equations indicates that the flumes were not tested for...

Movement of Sediment Mixtures in a Parabolic Flume with Simulated Rainfall
A 4-m long flume with parabolic cross section and adjustable slope was constructed to investigate the sediment carrying capacity and the variation of grain size distribution during deposition....
Predicting Human Instability in Flood Flows
The delineation of high flood hazard zones within a flood plain is usually independent of the parameters that constitute a life threatening situation. In order to define human instability...
Design of Expansions for Sub-Critical Open Channel Flow
Expansions for open channel flow at sub-critical velocity are required whenever it is necessary to reduce the velocity of flow from a structure which discharges into an erodible channel....
Upgrading Open-Wheel Pit Hydro Plants with Modern Submersible Hydroturbines
This paper presents a new approach in rehabilitating open-wheel hydrosites by using modern, standard submersible hydroturbines, open flume type cylinder gates, and high efficiency draft...
Field Efficiency Testing of Hydroelectric Turbines
The wide variability of conditions encountered in field testing of turbines is illustrated by examining two case studies with widely different scenarios. One site involved field acceptance...
An Empirical Correlation of Bed Load Transport Rates in Flumes and Natural Rivers
Rebuild of Ten Mile Intake Flume Structure for Electron Hydropower Project
In 1984 the Puget Sound Power and Light Company began a rebuild of what is popularly referred to as the 'world's crookedest railroad. ' The 'railroad'...
Visual Estimates of Flume and Weir Operating Conditions
Laboratory studies were conducted on a rectangular broad-crested weir to determine the effects of entrance and exit conditions on the prediction of discharge and required energy loss....
Submerged Flow in Parshall Flumes
Recent data collected in a 1-foot Parshall flume located in the Bureau of Reclamation's hydraulic laboratory indicate a significant discontinuity in the discharge/submergence...
