Sediment Discharge Measurement with a Point Sampler
A procedure for measuring total sediment discharge using point-source suspended-sediment data was developed. The proposed procedure, Total Sediment Discharge (TSD), was tested with field...
Effectiveness of Spur Dike Notching
The most widely used technique of ameliorating the environmental effects of river-training works has been to construct notches in spur dikes (or to allow notches to remain in damaged dikes)...
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...
Sedimentation Problems of the Illinois River Valley
Natural and manmade factors have drastically changed the character of the river and resulted in the accelerated deposition of sediments all along the entire river valley. The Illinois...
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...
The Policy Roots of Louisiana's Land Loss Crisis
Louisiana is currently losing approximately 155 square kilometers of highly productive wetlands to the Gulf of Mexico each year and the rate is accelerating. The physical cause of the...
Pass a Loutre Freshwater Diversions: Marsh Building in the Mississippi River Delta
Concern about the rapid loss of wetlands within the Pass a Loutre Wildlife Management Area located at the mouth of the Mississippi River has resulted in implementation of the Pass a Loutre...
Technique for Assessing Estuarine Sediment Pollutants
A technique was developed for the Mississippi Sound whereby all pertinent scientific data could be gathered and be assimilated in a format that would permit sediment pollution to be assessed...
Louisiana Estuaries: Issues, Resources, Status and Management
Louisiana has more extensive estuarine environments than any other state. These estuaries are comparatively young, having been formed in part by the building and destruction of lobes of...
Jean Lafitte's Real Legacy and Treasure
The Barataria Estuarine System is part of the Mississippi River which swept back and forth across Louisiana for thousands of years. Barataria Bay no longer receives the enrichment of the...
Lower Mississippi River Salt Intrusion Modeling
A laterally averaged numerical model called LAEM has been employed for both a 40- and 55-ft channel. In addition, LAEM has been applied with an increased height of the natural river crossing...
Modelmania
The idea that model testing could be useful in planning for the control of water in rivers and other waterways received little support in this country until John R. Freeman's...
Physical Modeling to Study the Extent of Removal of an Existing Lock and Dam on the Mississippi River
Locks and Dam No. 26 is located on the Mississippi River approximately 202. 9 river miles above the mouth of the Ohio River. This paper will discuss the utilization of a physical model...
Magnitude and Frequency Analysis in Large Rivers
A study of the magnitude and frequency of sediment transport was conducted on the Mississippi River at Natchez, MS, Red River at Alexandria, LA, and Pearl River at Bogalusa, LA. The individual...
Mississippi River Sediment Load and Regime Equations
Data collected by the Corps of Engineers were used to evaluate the interaction of such parameters as river slope, suspended sediment load, channel geometry, and river discharge. Calculations...
Loss of Aquatic Habitat in Quincy Bay
Quincy Bay is a backwater area along the upper Mississippi River near Quincy, Illinois. The construction in 1969 of a small boat access channel about 3. 2 km upstream of the natural bay...
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...
Comparative WWind Tunnel Testing of Bridge Road Decks
A 1:75 scale full aeroelastic model of the Quincy Bridge over the Mississippi River was tested in the National Research Council of Canada 9 m multiplied by 9 m wind tunnel. Tests were...
Changing Hydrology - The Middle Mississippi River
Observed daily flow and stage at major stream gages on the middle Mississippi River are numerically and graphically analyzed to quantify and illustrate the magnitude and seasonality of...
