Hydraulic Model Studies for Non-Federal Projects at Federal Dams—A Case Study
This paper will discuss the hydraulic model studies for hydropower projects developed by Arkansas Electric Cooperative Corporation (a non-federal entity) at existing Corps of Engineers...

A Case Study, Large Versus Small
This paper will review the hydraulic comparisons between the Lock and Dam No. 13 Hydropower Project, a 33-MW, low-head generating station near Fort Smith, Arkansas, and the Murray Hydroelectric...

Dardanelle Turbines
The Dardanelle turbines located at river mile 205.5 of the McClellan-Kerr Arkansas River Navigation System, are experiencing an unusual amount of wear in the blade trunnion bushings. Oil...

Modeling Nitrogen Movement Through Loess Soils
This study evaluates the ability of the Root Zone Water Quality Model (RZWQM) to track the movement and fate of nitrate (NO3--N)...

Monthly Conjunctive Allocation of Water Resources for Eastern Arkansas
The objective is development and use of a conjunctive water resource model as part of a hierarchical approach. In this case, this program is developed to determine the monthly allocation...

Relationship Between Scour Depth and Bend Radius of Curvature on the Red River
Studies of bank and bend processes were undertaken on the Red River between Index, Arkansas and Shreveport, Louisiana in connection with the navigation project on the river downstream...

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...

Natural Salt Pollution in the Brazos River Basin
Water quality in several major river basins in the Southwestern United States is seriously degraded by natural salt contamination. The salt originates from geologic formations underlying...

Managing Two Lakes with Significant Tailwater Fisheries
Norfork and Bull Shoals Dams on the White River in Arkansas were constructed in 1944 and 1951, respectively. The authorized purposes were for flood control, hydropower generation, and...

Changing Land Uses in the Platte and Arkansas Basins
Several water disputes among various parties in the Platte and Arkansas River Basins may have significant impacts on future land use practices. This paper describes five cases being litigated...

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...

Application of the GRASS Geographic Information System in a Sensitive Environment of the Arkansas River Navigation System
A Geographic Information System (GIS) was used to assist the selection of environmentally sensitive dredge material disposal sites along the Arkansas River Navigation System. Maintenance...

Method to Predict Cropland Ephemeral Gully Erosion
Erosion of farmlands due to concentrate flow is very severe on many unprotected fields across the county. Small channels can you in large gullies of not controlled. These small channels...

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...

The Sediment Weighted Histogram Generator and Estimation of Sediment Transport Trends
Long term sediment transport trends may be evaluated using a sediment histogram generator program that was written for microcomputers. Flows can be extracted directly from a compact disc...

Major Sedimentation (Erosion) Issues and Ongoing Research and Developments at the USDA-ARS
The U.S. Department of Agriculture, Agricultural Research Service (ARS) has research programs designed to produce techonology with which to predict, measure, and control erosion and sedimentation...

Major Sedimentation Activities in the Soil Conservation Service
The Agricultural Research Service (ARS) and Soil Conservation Service (SCS) are cooperating in the development of tools to improve prediction of the magnitude of erosion processes, the...

Some Insight in Autoregressive (AR) Spectral Modeling
The difficulties associated with the determination of reliable autoregressive (AR) approximations of the Pierson-Moskowitz and Davenport spectra are examined from the standpoint of developing...

On-Site Incineration
A variety of equipment is now available for incinerating hazardous wastes in situ. Thermal treatment, compared to land disposal, offers limited liability and immediate destruction. It...
