The Development of a Plan of Study to Evaluate the Physical and Biological Effects of Increased Navigation Traffic on the Mississippi River
An integrity team prepared a Plan of study (POS) that represents the first comprehensive effort on the Upper Mississippi River (UMR), to identify and quantify impacts associated with commercial...

Waves Generated by Recreational Traffic on the Upper Mississippi River System
Vessels of all sizes, from canoes to 15-barge tows, share the Upper Mississippi River System (UMRS), and every vessel interacts with the river by means of its displacement, propulsion,...

Studies on the Physical Effects of Commercial Navigation Traffic in the Upper Mississippi River
Changes in water velocity caused by passage of commercial navigation vessels were measured 180-500 ft (55-152 m) from shore at River Mile (RM) 504.8 in Pool 14 of the upper Mississippi...

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...

River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...

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...

Modelling of Stages of Nile River as a Tool for a Better Water Resources Management
As far as Egypt is concerned, the Nile is not just a river, it is rather the pulsing nerve of life. Consequently, it was essential to maintain detailed information about its levels and...

Overview of Mathematical Models?River Nile/High Aswan Dam
This paper has been directed towards the presentation of seven reliable planning tools (mathematical models) that can be used for the investigation of the planning options facing policy...
