Moving Toward the Millennium
The last decade of the 1990's is just beginning and paradoxically the water resources readily available to Clark County, Nevada are just ending. In a few short years Nevada's...
Risk Analysis as a Tool to Determine Spillway Design Capacities
Lyman Dam is an earth and rockfill structure located on the Little Colorado River approximately 11 miles south and upstream of St. Johns, Arizona. Several studies examining the safety...
Flow Distribution in Multiple Channels with Partial Ice Coverage
It is not uncommon for rivers to have multiple channels. The distribution of the total flow to the individual channels depends on their relative hydraulic characteristics of depth, width...
A Mathematical Model for Transport and Mixing of Oil Slick in Rivers
A two-layer two-dimensional mathematical model for transport and mixing of oil in rivers is presented. In this model, oil in the river is considered to consist of a surface slick moving...
Shop Creek Stormwater Quality Enhancement Project
The advent of NPDES regulations for stormwater discharges creates a need to verify, on a regional basis, the effectiveness of emerging water-quality control technologies such as extended...
Physical Modeling Study of the Niagara River Plume
A rotating laboratory facility is used to study the dynamics of the Niagara River discharge into Lake Ontario. The current tests are limits to buoyant discharge conditions, which occur...
In-Stream Thermal-Regime Analysis for Powerplant Coolant Dispersion
A steam-tube dispersion model has been adapted to real-time simulation of heat dispersion in a 7-mile reach of the Des Plaines River below Joliet Power Station. Direct feedback control...
Environmental Design of Channels?Can It Be Done?
The importance of environmental features to channel design is generally accepted and procedures for incorporating environmental features into flood control channel design have been developed....
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...
Identification Techniques for Bank Erosion and Failure Processes
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has developed techniques to design small flood-control channels. A component of this research is the...
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...
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...
Scour in Non-Cohesive Beds at Culvert Outlets
An empirical relationship was developed to estimate the depth of scour in non-cohesive material at culvert outlets. The scour depth is expressed as a function of mean particle size of...
Bed Sediments and Bed Forms of the Lower Mississippi River
Approximately 500 bed material samples were collected from the thalweg of the Lower Mississippi River. At each sample location, a sonic record of the bed was obtained. From the appearance...
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...
Variational Method in Fluvial Hydraulics?A Review
The theoretical base of the principle of minimum energy dissipation rate and other related stationarity hypotheses have been reviewed. Recent applications of the theory to the calculation...
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....
Modification to John H. Overton Lock and Dam
The Red River Waterway Project, Mississippi River to Shreveport, Louisiana, will consist of a navigation channel 9 feet (2.7m) deep by 200 feet (61.0m) wide, 5 locks and dams providing...
The Sediment Weighted Histogram Generator and Estimation of Sediment Transport Trends
Long term sediment transport trends may be evaluated using a sediment histogram generator program that was written for microcomputers. Flows can be extracted directly from a compact disc...
Operational Model Development for Salinity Control
The 800 km2 Breton Sound estuary and watershed in Louisiana is being modeled to characterize its salinity regime in terms of hydrometeorological...
