Scour-Hole Dimensions at Selected Bridge Piers in New York
Knowledge of scour-hole dimensions can be used by bridge engineers to deter mine the extent of countermeasures needed to prevent scour at bridge piers. Scour-hole widths at 128 piers,...

Design Guidance?Instream and Bank Restoration Structures
Despite an urgent need for river and stream restoration design criteria, little guidance has emerged in recent years. Existing guidance is largely unsatisfactory, promoting empiricism...

Design Guidelines for Bioengineered Bank Stabilization
Design of bioengineered slope stabilization measures in riverine environments to minimize rates of stream bank erosion requires accounting for hydrologic, hydraulic, geomorphic, geotechnical,...

River Restoration Considerations Beyond Channel Design
Restoration of river systems in highly disturbed environments poses unique challenges beyond channel design. The Jordan Creek Restoration project in Idaho was conducted in a valley disturbed...

Channel Scour Protection at Roadway Crossings
There are several forms of channel scour which may damage a bridge or culvert crossing over a natural or improved channel. Typical forms of scour include general degradation, local scour...

Use of Geomorphic Data for Assessing Stream Stability at Bridge Structures
The authors recently completed a statewide bridge scour evaluation for the Nevada Department of Transportation, which included evaluation of the geomorphic processes of bank erosion and...

Stream Instability in Loess Base Channels
The incision of bess base stream channels is a common and destructive response to alterations within a watershed in the midwest. Monitoring and evaluating procedures are being performed...

Channel Restoration Project along Toby Creek
Creek banks within Mecklenburg County, NC, are eroding, producing excessive quantities of sediment in the creek and causing bank instability. Seeking innovative approaches to these problems,...

South Platte River Restoration through Maintenance
This paper describes the use of restorative maintenance activities by the Urban Drainage and Flood Control District to clean up, stabilize and restore river banks and grade along the South...

Tributary No. 9 Restoration, Maryland State Highway Administration
The Maryland State Highway Administration agreed to accomplish restoration of 1,100 feet of stream channel as part of a mitigation agreement with the U.S. Army Corps of Engineers, Baltimore...

Fish Passage Pool Bedding Analysis
Anadromous fish passages, stream dynamics and the artifical channel segmented into a natural stream should fttnction seamlessly. This paper intends to develop reasonable procedures a designer...

On Silt Abrasion Erosion of Three Gorges Hydraulic Turbine in the Future
In this paper the basic parameters of Three Gorges hydraulic turbine have been reviewed and the operation characteristics of Three Gorges hydropower Station pointed out. Combined with...

Irrigation of Grain Sorghum on the Delmarva Peninsula
Irrigated grain sorghum experiments were conducted for two years on a Norfolk sandy loam soil. Full irrigation was compared to partial irrigation and no irrigation in a randomized block...

Third Party Impacts of Proposed Water Banking in the Colorado River Basin
Colorado River water is allocated to the seven Basin states based on a set of legal entitlements. Little flexibility is explicitly granted for addressing water shortages to particular...

Laboratory Evaluation of a Conductivity Probe for Scour Monitoring
Laboratory tests were used to evaluate the ability of conductivity sensors to measure streambed elevation. Tests were completed on a 2.1-m probe with a resolution of about 8 cm that was...

Bank Protection Toe-Downs and Local Pier Scour
The zone-of-influence for pier scour may impact bank protection toe-down depths. Countermeasures were required at a site along the Salt River in Phoenix, Arizona when the alignment of...

Design of Guide Banks for Bridge Abutment Protection
As an alternate to designing bridge abutments to withstand the development of the full scour prism predicted by equations currently available for estimating abutment scour, FHWA recommends...

Restoration Design for Urban Streams: Anacostia River Basin, Maryland
Several stream restoration projects have been undertaken by the Army Corps of Engineers in the Maryland portion of the Anacostia River basin. Measures used include bank stabilization,...

Effect of Reservoir Hedging on Crop Yield Under Deficit Irrigation Conditions
In case of irrigation projects, irrigation scheduling at the field has a direct bearing on yield crops. Hence, the various reservoir operating policies considered have to be evaluated...

Brownfields Boom
A brownfield is a leftover, unused industrial land parcel thought to have a prohibitively expensive clean-up required before developing. For years brownfields were battlefields for litigation...
