Computation of Gradually-Varied Flows in Channel Networks
For computing steady-state, gradually-varied flows, a new algorithm is presented which allows solution of the entire channel system simultaneously, and unlike other available methods,...
Hydraulic Study Requirements for Bulb Type Hydropower Units at a Navigation Lock and Dam
A replacement Lock and Dam at Alton, Illinois on the Mississippi River is presently under construction. This paper presents the results of studies performed for adding six bulb type hydropower...
Flood Routing Through Rock Dumps in Natural Channels
The paper deals with flow through rockfill to analyze the problem of flood routing through large masses of waste rock from mining operations dumped in natural channels. Rock dumps in ephemerous...
Data Acquisition and Control for Hydraulic Models
The Waterways Experiment Station is expanding the use of computer controlled data acquisition and control equipment on a variety of hydraulic models. These systems are presently being...
A Unique Communication System for Aerial Ropeways
The basic principles of operation of a Double Reversible Aerial Tramway are introduced. A brief note is given explaining a safety circuit or survey current used on the haul rope, since...

The Hydroelectric Barge
The nation's inland waterway system includes many low head locks and dams, with undeveloped hydropower potential estimated in excess of 1,100 MW. For most of these dams, hydro...
Surveying's New Promise: Centimeters from Space
One centimeter accuracy at far less cost than surveying by traditional methods is promised by the Global Positioning System (GPS). Signals from NAVSTAR satellites are received by two or...
River Lock Rehab: A Winter's Tale
Lock & Dam �1 on the Mississippi River between Minneapolis and St. Paul had deteriorated badly but the U.S. Corps of Engineers determined that replacement with a new structure...
River Meandering
The erosion and sedimentation processes associated with river meandering have a profound effect on man's use of rivers and their valleys, as well as the natural environment....
Thalweg Disposal: Demonstration of an Alternative
Disposal of dredged material in the main channel, or thalweg, is an alternative disposal option for maintenance dredging. The material dredged from the Upper Mississippi River is clean...
A Methodology for Open-Water Disposal Site Selection
Pascagoula, Mississippi, is the major industrial region in coastal Mississippi. The existing project, completed in 1965, provides for waterborne transportation from the Gulf of Mexico...
The Need for Training in the Dredging Industry
Training is very important in those cases where the skill of personnel is not adequate to make optimal use of dredging equipment. This holds for management staff as well as for operating...
Design and Construction - Theodore Ship Channel
Environmental impacts, greater technological capabilities, and improved evaluation techniques make the disposal of large quantities of dredge material more complex and involved. Also,...
Selection of Dredged Material Disposal Sites
Federal and state legislation regulating dredging of navigation channels along Maryland's Eastern Shore requires that local governing bodies provide the dredged material disposal...
Mississippi River Fairview Crossing Test
To improve estimates of shoaling rates in the crossings of a deep draft channel from New Orleans to Baton Rouge, a prototype test was conducted in Fairview Crossing at Mile 116 above Head...
Solving Channel Maintenance Problems at Reads Landing, MN
Dredging a sediment trap at the delta of the Chippewa River is being tested as a channel maintenance technique. It's designed to improve the Corps of Engineers predictive...
Ten Years of Long-Term Dredged Material Disposal Planning in the St. Paul District
Long-term dredged material disposal planning for the Upper Mississippi River by the St. Paul District had its beginnings with the Great River Environmental Action Team study (1975-80)....
Long-Term Management of Confined Disposal Areas
Systematic management of confined dredged material disposal sites is becoming increasingly necessary as competition for land use intensifies in regions in which most dredging projects...
