Practical Technology Resulting from MADE Research
As is often the case, when theoretical research is performed, practical technology is developed in the process. This has occurred with the Macrodispersion Experiment (MADE) conducted at...

Riprap Design Criteria for the ARS Low Drop Structure
The ARS low drop grade control structure has proven to be an effective means to stabilize incised channels in Mississippi. However, field inspections and laboratory testing have indicated...

River Dike Design Using a Numerical Model Approach
The preliminary design of a dike field at Redeye Crossing on the Mississippi River (Baton Rouge, Louisiana) is discussed. The TABS-2 modeling system was used to develop a two dimensional...

Field Measurement of Hydrodynamics and Sediment Transport of the Mississippi River at Old River
Two detailed field surveys of the hydrodynamics and suspended sediment transport of the Mississippi River at the Old River Control Structure complex were completed in February and June...

Sediment Sources Analysis for Peoria Lake Along the Illinois River
The modern-day lower Illinois River flows within a greatly oversized valley formed by an old course of the Mississippi River and glacial outwash events. As a result, the section of the...

Ambient Suspended Sediment Concentration and Turbidity Levels
The temporal variation of suspended sediment concentration and turbidity is an important component of the riverine environment. The maximum rate of discrete volumetric sample collection...

Two-Dimensional Hydrodynamic Modeling of a Reach of the Mississippi River in Pool 19
A depth-integrated finite-element model (RMA-2V) was applied on a section of the Upper Mississippi River to study the hydraulic characteristics of the floodplain-river system. The area...

Drought-related West Tennessee Channel Bank Failures
Massive bank failures occurred in 1988 along a 14-kilometer reach of the lower Obion River channel in Dyer County, West Tennessee where the river flows through an abandoned Mississippi...

One Power Plant, Two Job Sites
In response to the lingering questions about energy, officials from Vidalia, La initiated a plan in 1977 to build a hydroelectric plant at a site 90 mi northwest of Baton Rouge, where...

Site Specific Geologic Interpretations of Richton Salt Dome
There have been numerous investigations into the geological and hydrological aspects of the Richton Salt Dome area since its selection as a preferred site for a nuclear waste repository....

Sediment Management Challenges of the Red River Waterway Project
The Red River Waterway project consists of channel stabilization and construction of navigation locks and dams to provide a 9 foot minimum depth for a distance of approximately 236 miles,...

Water Measurement and Accounting of Lake Michigan Diversion
The diversion of water from Lake Michigan and the Lake Michigan Basin into the Mississippi River Basin has been regulated since the turn of the century. The U.S. Supreme Court Decree of...

Montgomery Point Lock and Dam Entrance to the McClellan-Kerr Arkansas River Navigation System
The McClellan-Kerr Arkansas River Navigation System has experienced a steady and positive increase in use. However, in the last 10 years changing conditions along the Mississippi River...

The Great American Pyramid
For more than 50 years officials of Memphis, Tenn. have wanted to establish a link to their Egyptian namesake--and they will, through a pyramid. As opposed to its Egyptian forerunners,...

Research Need on Integrated System for Water and Pest Management to Protect Groundwater Quality
Research is urgently needed to develop the technology for integrating the methodologies for managing soil, water, ground cover, pesticide applications, and fertilizer applications in such...

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...

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...

Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...

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...

Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...
