Overview of the US Army Corps of Engineers Flood Control Channels Research Program
The objective of the Flood Control Channels Research Program, currently being conducted at the US Army Engineer Waterways Experiment Station, is to develop design guidance and systematic...

Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...

Effect of Surface Water and Ground Water Interaction on Atrazine Transport to Pumping Wells
High concentrations of agricultural chemicals in flood waters have been reported in many Midwestern rivers and streams. The public water supply wells of a number of riparian communities...

Debris Basin Design Procedures
Debris basins are widely used in the southwestern areas of the United States, with the majority of the structures located in the Southern California area. More and more development is...

Application of Regime Theory in Practice: A Case Study
Alluvial channels are known to adjust their slope, width, depth and velocity to achieve stable conditions given a supply of water and sediment. Scientific investigations of stable channels...

California Border Environment Activities Since Passage of NAFTA
This paper presents a summary of the activities undertaken by the State of California to improve the border environment since passage of the North American Free Trade Agreement (NAFTA)...

Reduction of Downstream Impacts Through Use of Variable Detention Basin Volume Requirements
The Pre-post Match is the standard policy for regulating the design of detention basins for new developments despite evidence showing that as multiple developments occur in a watershed,...

Design Alternatives for Protection of the Santa Ana River Interceptor Sewer
The Santa Ana River Interceptor Sewer (SARIS) line buried within the floodplain of the Santa Aria River is being threatened by long term degradation of the river bed at the pipeline crossings,...

European Progress on river Renaturalisation
Most restoration projects in Europe have been designed to maximise species richness with little regard for channel stability. To recreate a sustainable natural channel it is necessary...

Role of Vegetation in Hydraulics of Channel Restoration
Boundary layer theory is used to develop a backwater model for flows through vegetated waterways which can be employed to approximately estimate flow depth variation in channel restoration...

Economic Risk Analysis as a Research Directing Paradigm
Risk analysis could be used to direct a manageable, prioritized strategic plan for evaluating bridge scour research needs. Through risk analysis, the costs of research and the potential...

Utilizing Geomorphic Analogs for Design of Natural Stream Channels
Engineering guidelines for the design of stable rock armored channels are well established. However, few guidelines exist for designers involved with the reconstruction of channels with...

Reduction of Sediment Loads in DEC Streams
The U.S. Army Corps of Engineers, Demonstration Erosion Control (DEC) project is actively involved in the stabilization and restoration of many drastically disturbed incising streams in...

Quail Creek: A Case Study of Restoration Using Native Materials
Quail Creek, a stream in northern Baltimore County, Maryland, was restored in 1990 using the approach developed by Rosgen to diagnose the problems, and determine the parameters for stable...

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...

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...

Channel Restoration of Incising, Mixed Grain Size Streams: Lessons Learned
Aquatic habitat restoration in incising sand and gravel bed streams disturbed by channelization and other human interventions has received little study. These channel systems are characterized...

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...
