The Formation of Meandering and Braided Channels
Flow in alluvial channels implies flow past boundaries that form and deform under the action of the flow. Interaction between the flow and the mobile boundaries produces channel patterns...
Application of Two-Dimensional Model to Predict Fine Sediment Deposition
The TABS-2 two-dimensional numerical modeling system was used to predict the potential for fine sediment deposition in the lock approach channels at Lock and Dam Nos. 4 and 5 on the Red...
Application of 2-D Model to Reduce Sedimentation Problems
The Corps of Engineers opened Lock and Dam No. 1 on the Red River Waterway in 1984. During the first runoff season, excessive quantities of fine sediment deposited in both the upstream...
Comparison of
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...
A Coastal Hard Rock Sediment Budget for the Inner Bristol Channel
The dominant input into the inter-tidal zone from the hard rocks bordering the inner Bristol Channel is clastic material. This is derived from coastal recession as a result of subaerial...
Mechanics of Mud Flows in Curved Channels with Uneven Beds
Most natural debris flows move through paths that are curved and that have significant bed topography. Owing to the dependence of the mechanics of wet debris containing substantial amounts...
Bank Failure and Erosion on the Illinois Waterway
In 1988, bank failure and erosion on the Illinois Waterway were evaluated. Banks were inspected from the air and from a motor vessel; thirty-one sites were examined in detail. Severe erosion...
Sediment Transport Due to Channel Flushing
Blocking of rivers and canals by sediment due to landslides or dumping of waste create problems of upstream flooding and drainage. Experiments are carried out in the present study on flushing...
Background and Applications of Fluvial-12
The computer program FLUVIAL-12 is formulated and developed for water and sediment routing in alluvial channels. The combined effects of flow hydraulics, sediment transport and river channel...
Surface Roughness with Erosion of Earth Channels
A determination of the stresses effective in soil detachment is essential in determining erodibility. The soil roughness that exists during testing and in natural channels is a key element...
Reducing the Potential for Flood Litigation
A flood event is usually followed by numerous damage claims that often lead to litigation. This paper proposes measures to mitigate the potential for litigation. It is stressed that an...
Identifying Causes and Predicting Effects of Bank Erosion
A number of causes of bank erosion in natural and disturbed environments are listed and described. Practical methods of predicting rates and directions of erosion in natural environments...
Geologic and Geomorphic Controls on Bank Erosion
Bank erosion is affected by both geologic (alluvial stratigraphy, sediment type, tectonics) and geomorphic (channel and valley morphology and history) variables. For example, present meander...
General Formulation of Best Hydraulic Channel Section
The best hydraulic channel section is determined by using Lagrange's method of undetermined multipliers. The approach presented is more general & easier to apply than...
Mechanics of River Bank Erosion and Protection State-of-the-Art Report 3: Federal Republic of Germany
Regulation and bank protection on German rivers and waterways have a long tradition. Major elements are alignment, revetments, groynes, longitudinal dikes and scour protection in bends....
Control of Bank Erosion in The Netherlands. State-of-the-art
In the Netherlands the protection against flooding and the effects of inland navigation have always been extremely important. Many problems related to these items, among them erosion and...
Effects of Vegetation on Floods at Four Arizona Sites
Four examples show the effect of vegetation on stage, discharge or frequency of floods. An 8-year growth of trees on the streambed at site 1 increased channel roughness enough to cause...
Model-Prototype Comparison of the Bay Springs Lock, Tennessee-Tombigbee Waterway, Mississippi
A comprehensive prototype evaluation of the Bay Springs Lock, Tennessee-Tombigbee Waterway, Mississippi, was conducted by the Hydraulics Laboratory, Waterways Experiment Station (WES)....
Model Study of New Bonneville Lock
The filling and emptying system of the New Bonneville Lock was designed by the US Army Engineer District, Portland. The lock will be 86 ft wide by 675 ft long, with a design lift of 69.5...
Model Study of New Madrid Pumping Station
The proposed pumping station on the New Madrid Floodway consisted of a draft tube type sump design (referred to as a formed suction inlet) to eliminate swirl and provide a more uniform...
