Monitoring Water Quality: Neches Estuary, Texas
A continuous monitoring project has been established in the Neches Estuary of Southeast Texas, for the purpose of investigating the influence of tidal hydraulic on sedimentation in a floating...
A Simulation Technique for Modeling Flow on Floodplains and in Coastal Wetlands
The system design is premised on a proven, areal two-dimensional, finite-difference flow/transport model which is supported by an operational set of computer programs for input data management...
A Model of Flow in Regulated Open Channel Networks
A model (NETWORK) is presented for the simulation of unsteady flow in regulated open channel networks. The operation of hydraulic structures, such as gates and weirs, are simulated as...
Physical River Model Results and Prototype Response
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has performed physical hydraulic model studies on various rivers for nearly 60 years. These studies...
Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...
Modeling of a Low Head Hydroelectric Project
In order to shorten the time to develop a hydroelectric project at the Corps of Engineers Hannibal Lock and Dam on the Ohio River for the City of New Martinsville, West Virginia, a turnkey...
Channel Response to SCS Type-C Grade-Control Structures on Burney Branch, Mississippi
Five SCS Type-C grade-control structures were installed in Burney Branch in 1980 to remove 59.4 feet (18.1 m) of grade. The performance of the structures was evaluated in 1984 after they...
Simulation and Video Animation of Canal Flushing Created by a Tide Gate
A tide-gate algorithm was added to a one-dimensional unsteady flow model that was calibrated, verified, and used to determine the locations of as many as five tide gates that would maximize...
Analysis of Spillway Failures by Uplift Pressure
Results of a model study to evaluate the development of uplift pressures beneath concrete chutes are presented. Two spillway failures are described to support the study results. Common...
Design and Performance of Earth Spillways
The U.S. Department of Agriculture's Soil Conservation Service has designed and administered construction of a large number of dams utilizing grassed earth-lined auxiliary...
Bay/Delta Hydraulic Model?Thirty Years of Service
The San Francisco Bay and Delta is an extremely complex estuarine system. During the past thirty years, the San Francisco Bay/Delta Hydraulic Model has proven to be a valuable scientific...
Performance Evaluation of Channels Stabilized with ARS-Type Low-Drop Structures
Field and hydraulic investigations of seven ARS-type low-drop grade-control structures located in Mississippi indicate that most of the structures become submerged during flows with recurrence...
Alternate Designs for the Sidewalls of Hydraulic Jump Stilling Basins
This paper discusses several alternate designs to replace the full height sidewalls of a type 2 U.S. Bureau of Reclamation stilling basin. The alternate designs that were investigated...
Modeling Side-Weir Diversions for Flood Control
Side-channel weirs can be used for diversion to reduce flood peaks. This study has developed a means for incorporating the effects of side weirs in HEC-1 and HEC-2 calculations through...
Gas Transfer at Hydraulic Structures
Field measurements of gas transfer at hydraulic structures are notoriously difficult and imprecise. A technique which measures the transfer of hydrocarbon tracer gases has been tested...
Studies of Hydraulic Jump by the Flow Routing
The high energy of floodwater passing from a reservoir needs to be dissipated to prevent scouring and damage from the dam and other downstream structures. Hydraulic jump is a common way...
Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....
Dam Safety, Yes.; But What About Safety at Dams?
Design and construction of safe structures are the professional obligations of hydraulic engineers. However, there are environmental dangers with safe structures which engineers often...
Hydrologic Safety of Earth Dams
Hydrologic and hydraulic analyses are presented pertaining to the safety evaluation of an earth dam located downstream of another smaller earth dam. The upper dam is assumed to breach...
