Response of a Lake Outlet Channel to Dredging
Channel improvements were completed in 1982 along approximately 8 miles of the Little Tallahatchie River just downstream of Sardis Dam. Heavy rains shortly after completion of the improvement...

Development of a Monitoring Program and Vegetative Restoration Project in a Mississippi River Bendway
The Dry Bayou-Thompson Bend area is located on the right descending bank of the Mississippi River between river miles 4. 5 (7. 2 kilometers) and 30. 0 (48. 3 kilometers) above the confluence...

Modification of Meander Pattern Using Wing Dams
A sharp river bend and a highway bridge together create potentially hazardous conditions for all down-bound barge tows on the Mississippi River at Lansing, Iowa. The tendency of the river...

Stream Width Adjustment to Upstream Loading
Channel width adjustments takes place either by fluvial erosion or accretion of the banks, or by their mass failure under gravity and subsequent removal of the slump debris. Simulation...

Sediment Routing and Stream Bed Evolution Model
A one-dimensional numerical model developed by Borah, Alonso and Prasad is discussed, improved and tested. The model named STREAM routes graded sediments and simulates aggradation, degradation...

Red River Pilot Channel Design and Development
This paper presents the design parameters for two pilot channels constructed on the Red River. The factors often associated with the development of pilot channels are identified in an...

Roughness Coefficients of Large Floods
Most hydraulic calculations of flow in channels and overbank areas require an evaluation of flow resistance generally expressed as Manning's roughness coefficient, n. Literature...

Water Rights Considerations Associated With Channel Conveyance Losses
During 1986, the Wyoming Water Research Center and the State Engineer's Office cooperatively did a study on the conveyance losses associated with a section of stream channel...

Estimating Number and Duration of On-Times for Surge Irrigation
Research shows surge flow can achieve efficient and uniform irrigation on some soils. However, most available information focuses on computerized analysis and modeling for research purposes....

Theoretical Flow Model for Drop Structures
A theoretical model based on the momentum equation is reviewed for a trapezoidal weir drop structure operating in a trapezoidal channel. Preliminary qualitative results indicate agreement...

Application of the New SCS Time of Concentration Method
The second edition of the Soil Conservation Service (SCS) TR-55, published in June 1986, introduces a new method for calculating the time of concentration for storm runoff flowing through...

Bending Strength of Thin Cold-Formed Steel Straight Panels
An experimental investigation on the bending strength of 26 gage cold-formed corrugated steel straight panels with web-depth to thickness (h/t) ratio of 475 is presented. A typical test...

Landslide Dams in Japan
Damming of rivers by landslides is common in Japan because widespread unstable slopes and narrow valleys exist in conjunction with frequent hydrologic, volcanic, and seismic landslide...

Terminal Development as Affected by New Generation Ships
Howland Hook Marine Terminal, New York, serves to illustrate how an existing terminal, built to the older standards, can be adapted to accommodate these larger ships that not only stretch...

Planning for Deep-Draft Navigation Channels
This paper summarizes the trends in seaboard trade, the major commodities for the world, and the share captured by U. S. ports. The discussion includes the new developments of port planning...

Ship Wave Prediction for Port and Channel Design
Several laboratory and field investigations of ship-generated waves have been conducted during the past twenty-five years. Typically, for a given ship, reported data consists of the height...

Navigation Channel Design for Safe and Efficient Ship Transit
The U. S. Army Engineer Waterways Experiment Station (WES) recently conducted a hydraulic model investigation of the western portion of Cleveland Harbor, Ohio. This study provided data...

Channel Design Criteria and the Houston Ship Channel
Channel design literature is reviewed and compared with operational limits currently on the Houston Ship Channel (HSC). It was found that in all aspects of channel design considered (depth,...

Additional Benefits from Channel Improvements
This paper describes techniques used to quantify three types of benefits resulting from enlarging the Houston Ship Channel. These benefit types are vessel casualty reduction, delay reduction...

Analytical and Empirical Methods for Predicting Channel Shoaling
Many techniques have been used in the past to predict the effects of channel enlargement on channel shoaling. These range from rule-of-thumb predictions to elaborate physical model investigations....
