Example of the Stable Channel Design Approach
This paper shows an example application of a new method being packaged by the US Army Engineer Waterways Experiment Station to aid in the design of stable flood-control channels. A stable...
Stable Channel Analytical Design Method
The Flood-Control Channels Research Program is being conducted at the US Army Engineer Waterways Experiment Station to develop systematic methods for design of stable channels for small...
Failure Modeling of Hydraulic Systems
Techniques of survival analysis are investigated for modeling the failure of hydraulic systems. The Proportional Hazards Model has the advantage of being able to separate the effects on...
Optimal Design of Highway Drainage Structures
Hydraulic design of a bridge or culvert using a risk-based approach is to choose among the alternatives the one associated with the least total expected cost. In this paper, the risk-based...
Conceptual Evaluation of Dam Safety by Instrumentation
The criteria governing the design of dams can frequently be imprecise. One of the most practical methods of evaluating dam safety in the dam safety surveillance programs is to check the...
Conservativeness in Hydraulic Engineering Studies
Hydraulic engineers routinely make a variety of assumptions during the course of a study. Assumptions, once made, usually become incorporated into the fabric of the study and are seldom...
Channel Network Analysis Using Simultaneous Solution Algorithm
In this paper, a simultaneous solution algorithm for one dimensional unsteady flow routing through channel networks is introduced. This direct solution algorithm is based on the double...
Stability Criteria for Revetments
A simplified 'black box' approach is presented for a number of revetment systems for banks and shore protection. The design criteria, based on the physical similarity...
The Influence of Uniformity on Riprap Stability
Studies have shown that size uniformity influences the stability of riprap. The ratio of fractional sizes of the riprap mixture, D60/D10,...
Riprap Stability Results from Large Test Channel
Velocity data from a large test channel were used to determine the distribution of depth-averaged velocity and shear stress on the side slope of both straight and curved channels. From...
Design and Construction of Soil-Cement Drop Structures
Soil-cement has been used as an effective and economical slope protection material for embankment dams and stream banks. This paper describes the use of soil-cement in the construction...
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...
Physical Modelling of Self Forming Alluvial Channels
A method is presented for the determination of a practicable physical model of self-forming channels in cohesionless alluvium. Both sand bed and gravel bed regime channels are considered....
Uncertainty Estimates for Rainfall-Runoff Model
Almost all rainfall-runoff link-node models in use today involve the subdivision of the catchment into smaller areas, linked together by a system of channel links. These 'link-node'...
Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...
Mt. Elbert Pumped Storage Trashrack Failure
The failure of three trashrack sections for unit 2 at the suction-draft tube intake occured after one year in service. However, the trashracks for unit 1 had five years of service with...
Guard Gate Tests at Tieton Dam
The emergency gate hoist system on the guard gates at Tieton Dam, near Yakima, Washington, was tested as part of the United States Bureau of Reclamation Safety Evaluation of Existing Dams...
Scale Effects of Overflow-Oriented Hydraulic Parameters for a High Dam
This paper presents the findings of prototype observation and model verification on the surface velocity, the range of nappe jetting, and the diffusion regime of the discharged flow related...
Characteristics of the Flood Release-Induced Vibrations with Qianshui Thin-Arch Dam
In this article the prototype observations and design analyses are described regarding the flood release-induced vibrations of the Qianshui thin-arch dam and its foundation; and their...
Conservation Properties of Flow Simulation Models
The fundamental equations of fluid mechanics and hydraulics posses certain integral properties which should be maintained by their discrete analogs. In this paper the conservation properties...
