Research to Application: Network Models to Simulate Flow and Transport in Heterogeneous Media
Effective groundwater cleanup requires accurate site-specific information on cleanup processes. Numerical simulations limit the need for expensive field experiments and provide details...

Development of Remediation Technologies Simulators
This paper summarizes on.going efforts to develop software for simulating various in situ, subsurface remediation technologies to improve remediation selection, design, and operation....

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...

Coping with EPA's Storm Water Permit for Hazardous Waste Facilities, Industrial Landfills, Wastewater Treatment Plants, and Recyclers
The Environmental Protection Agency (EPA) has released NPDES storm water monitoring data from group applicants. This paper will analyze that data to determine which pollutants are present...

An Appropriate Technology to Treat Domestic Sewage
Various alternative wastewater treatment systems (AWWTS) are outlined and attention is drawn to a low cost sustainable wastewater treatment system that has been functioning satisfactorily...

Maryland SHA's Procedure for Assessing Existing Bridges for Scour Vulnerability and for Rating Unknown Foundations
The Maryland State Highway Administration developed a recommended screening procedure for rating existing bridges for Item 113, Scour Critical Bridges, in the National Bridge Inventory...

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...

Appropriate Sanitation Technology Advisor: A Planner's Tool in Less Developed Countries
The goal of the expert system (ES) prototype described in this paper is to create an advising method for planners, engineers and officials in Less-Developed Countries (LDCs) to utilize...

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...

An Introduction to Taipei Suburban Sewage Collection and Treatment Systems
Taipei Suburban Sewerage System covers the lower Tansui River Basin located in Northern Taiwan The planning area (excluding Municipality of Taipei) consists of 14 township in Taipei County...

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...
