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...
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...
Water Quality Mitigation for the San Joaquin Hills Transportation Corridor
The San Joaquin Hills Transportation Corridor (SJHTC) is a 24 km Design/Build tollway which has been financed with bonds to be paid back with toll revenue. The Environmental Impact Statement...
Navigation Lock Improvements
All commercial barge traffic on the Upper Mississippi River and Illinois Waterway must pass through a system of locks designed and built in the 1930s and 40s. Many of the locks on these...
Evaluating Sustainability of Water & Sanitation Projects: Case Studies in Developing Countries
Studies carried out in the water and sanitation sector in eight developing countries have delineated the most important factors related to sustainability. These are capacity and skills...
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...
Environmental Restoration Measures on the Tennessee-Tombigbee Waterway (TENN-TOM)
The Tenn-Tom, opened to navigation traffic in 1985, was designed and constructed to promote environmentally sustainable development. During the past ten years, the original measures have...

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...
Simulation of Dissolved Oxygen in Sacramento-San Joaquin Delta
A one-dimensional model has been developed to simulate water quality in a complex multi-channel estuarine system. The model utilizes a Lagrangian reference frame for transport computations....
Predicting THM Formation with Artificial Neural Networks
An existing mathematical model to predict trihalomethane formation and speciation was enhanced through the use of artificial neural network technology. The model corresponded well with...
Comparison of Worst-Case and Probabilistic Approaches to Ocean Outfall Mixing Zone Analysis
