Selection of Sediment Transport Relations: Part I, Review of Sediment Transport Comparisons
There are a great number of sediment transport relations in existence in the world today. The engineer is often faced with the problem of choosing the most appropriate relation for the...

Selection of Sediment Transport Relations: Part II, Ranges of Dimensionless Numbers
With a large number of sediment transport equations claiming to be applicable within various ranges of hydraulic and sediment parameters, engineers are often faced with the dilemma of...

Selection of Sediment Transport Relations Part III: Numerical Ranking of Sediment Transport Relations
The emphasis of this paper is the methodology for the selection of sediment transport relations and is applicable for analysis of any sediment transport relation. However, to illustrate...

Hydrodynamic Changes Associated with Navigation Traffic on the Upper Mississippi River System
Research has been conducted at the Illinois State Water Survey for the last five to seven years to collect field data from the Illinois and Mississippi Rivers to determine the extent and...

Distributions of Return Flow in Navigable Waterways
Physical impacts of barge traffic on the riverine environment have drawn increasing attention from resource managers of the Upper Mississippi River System (UMRS). Return flow, which can...

Are Erosion Control Programs Reducing Sedimentation?
In the Midwest, the USEPA National Watershed Monitoring Program is determining the effectiveness of land management strategies to improve water quality and biological diversity. The illinois...

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...

How to Manage Floodwaves in the Dutch Meuse: Future Measures to Reduce the Inconvenience of Inundations
This study showed that in the Gravelmeuse the combination of nature development and reducing of inundation inconvenience is possible. In the framework of the obliged supply of a fixed...

Influence of Flooding Events on Suspended Matter Quality of the Meuse River (The Netherlands)
Flooding events of the Rhine and Meuse Rivers have struck The Netherlands in 1993 and 1995. In the Meuse River basin, the river forelands have been widely used for housing and agro-industrial...

Professional Associations Offer Design Resources for Civil Engineers
A civil engineer is trained academically and professionally to meet the challenges and solve the problems of ever expanding world populations. With an increased demand for civil engineers...

Industry Standards for Erosion Control Products�Future Tools for Civil Engineers
In 1990, the International Erosion Control Association (IECA) formed a Cooperative Standards Program (CSP), directed by the IECA Committee on Standards. The purpose of the CSP is to develop...

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...

Restoration of Abandoned Meanders on the Middle Fork Forked Deer River, Tennessee
The Middle Fork Forked Deer River in western Tennessee historically had a sinuous course within a wide floodplain. In the early 1900's, local interests dug large straight...

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...

Contraction Scour at Bridges: Analytic Model for Coarse-Bed Channels
Contraction scour at bridges spanning coarse-bed channels is evaluated based on mass conservation of both water and transported sediment between a reference channel section near the crossing...

Mitigation Measures for Eroding Muddy Shores
A criterion for the stability of muddy coasts is proposed, accounting for bottom resistance, hydrodynarnic forcing and sediment supply. Although qualitative, this criterion provides a...

A Comparison of Sediment Routing Models
In this paper the authors have compared the performance of coupled linear and non-linear methods of solution from these generic types, in order to assess their suitability for use in optimisation...

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...

Sediment Deposition in the Navigation Approach Channel of Three Gorges Project
In this paper, a comparison is made between the problems of sediment deposition in the navigation approach channel of Gezhouba and Three Gorges Project. The investigation shows that the...

Estimating Sediment Conveyance Capacity and Deposition Potential in Culverts
In watersheds characterized by high sediment production, culverts must be designed to adequately convey both water and sediment without causing excessive backwater upstream of the culvert...
