Groundwater Transport Modeling Using Fuzzy Sets and Fuzzy Logic
Modeling of groundwater flow and transport is inherently uncertain. The predictive capability of the model depends upon both the quantity and quality of hydrogeologic data. The introduction...

Considerations Regarding Geochemical Transformations Downstream of Subsurface Wastewater Effluent Disposal Facilities
Many suburban and rural communities use subsurface disposal in conjunction with on-site and other small decentralized systems. In addition, to reduce the impacts of wastewater treatment...

Watershed Modeling for Surface-Groundwater Interaction
Groundwater use has increased rapidly due to irrigation development in the Great Plains. This is especially true in the Republican Basin that intersects the three states of Nebraska, Kansas...

Hydrologic Comparison of Four Types of Permeable Pavement and Standard Asphalt in Eastern North Carolina
A permeable pavement parking lot in eastern North Carolina consisting of four types of permeable pavement and standard asphalt was monitored from June 2006 to July 2007 for hydrologic...

Hurricane Protection System
This chapter discusses hurricane protection systems. Topics include standard project hurricane, levees and floodwalls, datums and elevations, and interior drainage and pump stations....

The Need for Geotechnical Investigation
Knowledge of the subsurface conditions is needed to decide which type of foundation to use. In the discontinuous permafrost zone, some generalizations may be made about the location of...

Effects of Agricultural Drainage on the Baseflow in the Minnesota River Basin

Beans Help Build Deep Drainage Trenches

Pile-Head Behavior of Rigidly Capped Pile Group

Application of TOPNET in the Distributed Model Intercomparison Project (DMIP)
This paper describes the application of a networked version of TOPMODEL, TOPNET, as part of the Distributed Model Intercomparison Project, DMIP. The model implementation is based on a...

Fate of Nitrogen Compounds in Animal Waste Lagoons
This chapter examines the fate of nitrogen compounds in animal waste lagoons. Topics include nitrogen in animal waste lagoons; transformations and removal; and subsurface transport....

Water Quality Aspects of Irrigation and Drainage: Past History and Future Challenges for Civil Engineers
This paper presents a brief history of irrigation and drainage related to ASCE activities on its Jubilee. This paper discussed legislation and policies that affect irrigation and drainage...

Advancing Under London
Bored tunnels account for more than 20 percent of the Channel Tunnel Rail Link, the high-speed rail line that will connect the Channel Tunnel with London upon its completion in 2007. In...

Storm-Water Strategy
Water pollution laws are certainly nothing new, but increased public scrutiny, beach closures, and media coverage—particularly in Orange County, California—have placed new pressures on...

Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data
Development of the referenced Standard began in 1996. It is slated for publication in summer of 2002. The intent of this standard guideline is to present a system of classifying the quality...

Non-Destructive Excavating Around Pipelines and Challenging Conditions
Hydrovac technology provides engineers and contractors with a unique solution for non-destructive excavating around sensitive buried lines. As a non-mechanical excavating method, it is...

Fluid Flows and Reactive Chemical Transport in Variably Saturated Subsurface Media

Draining in a New Direction
(Available on in special edition) Wick drains can stabilize slopes and landslides by accelerating soil consolidation and settlement. But conventional wick drains, driven vertically into...

Replacement Strategy
Water Works II, a $275-million water treatment plant currently under construction in Detroit, is redefining the way that such projects are let and built. In 1980 the city initiated a program...

Water Quality Restoration of the Mammoth Cave Karst Aquifer: A Work in Progress
Over tens of thousands of years the aquatic ecosystem of the Mammoth Cave Karst Aquifer evolved in concordance with natural recharge supplied through 24,000 hectares of tall-grass prairie...
