Numerical Accuracies in Steady Open Channel Flow
The authors have reviewed the accuracy of the individual terms and formulations of the conservation of energy equation as used within the constraints of steady open channel flow modelling....
Sediment Transport, Hydraulic Retention Devices, and Aquatic Habitat in Sand-Bed Channels
Streams and rivers of all sizes and in all parts of the United States flow on sand-bed channels. Scour, Transport, and deposition of sediments particles are natural processes in these...
Sediment Transport and Aquatic Habitat in Gravel-Bed Rivers
Gravel-bed rivers experience dymanic conditions of flow and sediment transport. Long periods of bed stability are interrupted by shorter periods of bed mobility when major changes and...
Chute Design Using Concrete Building Blocks
Chutes constructed using concrete building blocks for erosion control on ephemeral streams have performed successfully. The chutes consist of a layer of blocks placed on a geotextile over...
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...
Model Study of the Guadalupe River Bypass Culvert
A hydraulic model investigation of proposed channel improvements for the Guadalupe River Channel was conducted at the US Army Engineer Waterways Experiment Station in Vicksburg, Mississippi....
Hydraulic Engineering
This proceedings consists of papers presented at the ASCE National Convention on Hydraulic Engineering given July 30 to August 3, 1990 in San Diego, California. The Conference provided...
Leveling the Playing Field
As professional sports grow, so does the market for elaborate multi-use sports arenas. The new Target Center in Minneapolis features a unique movable floor, 68 luxury suites and a state-of-the-art...
Identification and Characterization of the Collapsing Alluvial Soils of the Western United States
Suggested procedures for the identification and characterization of the collapsing alluvial fan, mudflow and debris flow deposits of the arid and semi-arid parts of the western United...
Analysis of Barrier Island Dynamics for Ship Channel Planning at Ship Island, Mississippi
Ship Island is located among a chain of barrier islands approximately 18 km south of Biloxi, Mississippi. During initial construction of Gulfport Harbor Ship Channel, 1901-1905, the channel...
Sediment Processes and the Houston Ship Channel
A year-long field and laboratory study of sediment oxygen demand was conducted on the Houston Ship Channel. The primary objective of the work was to better understand the processes controlling...
Effect of Flow Conditions on Stream Reaeration Coefficients
Contrary to the findings of previous studies of channel-controlled stream reaches, it was found that, in four reaches of a small stream characterized by a series of pools and riffles,...
Channel Routing for Improved Flood Control
Lake Wappapello, located on the St. Francis River in southeastern Missouri, is operated by the St. Louis District (SLD) Corps of Engineers for purposes of flood control and recreation....
Computerized Decision-Guidance System for Management of the Trent River Multireservoir System
A computer simulation model has been implemented for a complex multireservoir system, composed of 44 reservoirs and 52 channels. The model is designed in modular form to forecast inflows,...
The Formation of Meandering and Braided Channels
Flow in alluvial channels implies flow past boundaries that form and deform under the action of the flow. Interaction between the flow and the mobile boundaries produces channel patterns...
Bed Waves Generated by Internal Waves in Alluvial Channels
The flow in an alluvial channel is conceived as a stratified flow both with respect to the velocity- and density-distribution. In such flows internal waves may occur which influence the...
Comparison of
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...
Derivation of a Stability Principle from the Shields Criterion
The widely used specific energy equation, which defines the subcritical and supercritical states of the open channel flow, is a direct result of the integration of the Froude number corresponding...
An Alternative Approach to Erosion Control and Mitigation
A case study is presented in which a sediment engineering investigation was conducted to determine the potential effects of a change in flow regulation on the channel downstream of a lake,...
Channel Entrenchment Along the Post Creek Cutoff in Southern Illinois
The Post Creek Cutoff was constructed in 1915 by the Cache River Drainage Commission to divert flow from the Upper Cache River to the Ohio River. The construction of the cutoff reduced...
