Computer Aided Hydraulic Design of Open Channels
Over a 10 year period, the computer program, WASURO, was developed by the U.S. Army Corps of Engineers District, Los Angeles (LAD), which utilized many of the criteria of the previously...
Power Formula for Open-Channel Flow Resistance
This paper evaluates various power formulas for flow resistance in open channels. Unlike the logarithmic resistance equation that can be theoretically derived either from Prandtl's...
Calibration of Water-Velocity Meters
The U.S. Geological Survey, Department of the Interior, as part of its responsibility to appraise the quantity of water resources in the United States, maintains facilities for the calibration...
Flow Measurement Using a Digital Pressure-Time Method
This paper describes flow measurements performed by TVA's Engineering Laboratory as a part of absolute efficiency measurements of the two units at the Great Falls Hydro Plant....
Closed-Loop Control for Hydraulic Laboratory Operation
The implementation of Closed-Loop Feedback Control in the Bureau of Reclamation's Hydraulic Laboratory flow delivery system has provided an important new modeling tool for...
Estimation of Urban Stormwater Quality
Two data-based methods for estimating urban stormwater quality have recently been made available - a planning level method developed by the U.S. Environmental Protection Agency (EPA),...
Instrumentation for a Dry-Pond Detention Study
A 12.3-acre, fully urbanized, residential land-use catchment was instrumented by the U. S. Geological Survey in Topeka, Kansas. Hydraulic instrumentation for flow measurement includes...
Applications of GSTARS Model
GSTARS is a Generalized Stream Tube model for Alluvial River Simulation. Depending on an engineer's need, GSTARS can be used as a fixed boundary as well as a movable boundary...
Mathematical Modeling of Compound Channel with High Sediment Concentration
The mathematical model for erodible channels, FLUVIAL-12, has been extended to simulate the fluvial processes in the lower reach of the Yellow River in China. Fluvial processes in the...
The Bureau of Reclamation in Transition
Recognizing and responding to the changing climate in water resources, the Bureau of Reclamation recently launched a massive effort to redirect the agency's traditional mission....
The Changing Role of the U.S. Bureau of Reclamation
The Bureau's reorganization will enable it to more effectively and efficiently meet changing water resources needs in the western states. The new role of the Bureau is particularly...
Toe Scour Protection in Open Channels
Scour at the toe of bank protection works is one of the major causes of failure of these structures. Weighted riprap toes are frequently used to prevent bank protection failure due to...
Evaluating Flood Hazards on Alluvial Fans
In 1982, the Federal Emergency Management Agency (FEMA) developed a methodology for the determination of flood hazard zones and base (100-year) flood elevations on alluvial fans for administering...
Computations of High-Velocity Flows on Alluvial Fans
The results of numerical models of supercritical flows on alluvial fans demonstrate the strong effect fan topography has on flow velocity and depth. Particularly important are transverse...
Initiation of Density Currents in Diverging Channels: Comparison of Field and Laboratory Data
The transition from free surface channel flow to a submerged density current has been investigated in the laboratory. A set of field data has been collected at a wastewater effluent site....
An Alternate Theory of Density Current Propagation
Density current propagation has been previously analyzed by employing a one-dimensional momentum balance in a frame of reference moving with the density current head. Experimental data...
Interfacial Instabilities Associated with Density Currents
Three-dimensional behavior of density currents flowing down a sloping surface has been analytically and experimentally investigated. Attention has been given to the presence of interfacial...
Effects of Basin-Wide On-Site Stormwater Detention
The effect of basin-wide on-site detention of storm water runoff from developed areas is investigated to determine its effectiveness in reducing peak discharges in downstream portions...
Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...
An Inline Retarding Basin
This paper discusses the idea of retarding flows within existing right-of-way in a linear basin. This concept is based on longitudinally dividing the right-of-way into two sections. The...
