Education and Research Needs for Appropriate Technology
Appropriate technology and sustainable development are inextricably interrelated and the engineering profession is increasingly realizing that greater care must be given to taking these...
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...
Eastern San Joaquin County Groundwater Management
An aquifer system of significant volume is located in Eastern San Joaquin County (ESJC), part of California's Central Valley. The industry in that region is primarily agriculture,...
Management of Stream-Aquifer Systems in the 21st Century
Many water agencies, especially those in the arid and semi-arid southwest of United States rely on stream-aquifer systems for a significant proportion of their water supplies. Wastewater...
Groundwater Flow Component of a Wetland-Dynamics Model
A 3-D groundwater flow model was developed to study the hydrology of groundwater-fed wetlands. Initial model results, including steady and unsteady simulations, compare well with existing...
Environmental Policy Making in Today's Political Environment
There are many philosophical and political forces of change in America today which are molding the environmental agenda of the 104th Congress. What is the proper role of the federal government?...
Comparison of General vs. Multi Sector NPDES Storm Water Permits
In November 1990, in response to the 1987 amendments to the Clean Water Act, the EPA initiated the National Pollutant Discharge Elimination System (NPDES) storm water permitting program....
San Diego County Water Authority's Emergency Storage Project: A Major Planning Achievement
The San Diego County Water Authority (Authority) has been actively working to maximize the security of the future water needs of the community it serves. The Emergency Storage Project...
The Standley Lake Protection Project
Until recently, there has been no physical separation between potentially contaminated runoff from the former Rocky Flats Nuclear Weapons Plant and Standley Lake, the nearby water supply...
Stormwater Management for San Joaquin Hills Transportation Corridor, Orange County, California
San Joaquin Hifis Transportation Corridor (SJHTC or Corridor) is one of the largest design-build toll roads in U.S.A. To meet stringent environmental mitigation requirements, to ensure...
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...
Improving the Speed of Double Lockages
The size of tug and barge combinations on the Upper Mississippi River and Illinois Waterway frequently exceed the dimensions of the lock chambers they must pass through. The locks on these...
The Sawmill Creek Watershed Restoration Project
The Sawmill Creek project is a comprehensive watershed restoration effort. The goal is to demonstrate that existing programs can be coordinated in order to improve water quality, and habitat...
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...
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...
Automated Tools for Spatially Distributed Rainfall/Runoff Modeling
A watershed modeling system (WMS) has been developed to address the needs of surface water rainfall/runoff computer simulations. WMS, developed at the Engineering Computer Graphics Laboratory...
