Specifications for Design-Build Projects
This chapter discusses the various specifications that come with a design-build project, including owner-generated specifications and contractor-generated specifications....

Fundamentals of Risk Assessment
Risk, expressed in terms of potential human sufferings and economic losses, is very real and its significance is particularly important when considering natural hazards. For effective...

Project Definition and Conceptual Design
In order to select a DB contractor, the owner must define its requirements for project implementation and for the completed project. These requirements are typically incorporated into...

Concentrated Animal Feeding Operations (CAFOs) and Nitrogen Conversions in the Groundwater Environment
EPA's regulatory focus on concentrated animal feeding operations has historically concentrated on potential surface water impacts from direct discharges as well as nutrient-laden runoff....

Permits, Surface Water/Groundwater Baseline Sampling, and Analysis of Dewey-Burdock In Situ Uranium Project in Fall River County, South Dakota
Powertech Uranium Corporation has proposed to conduct in situ mining within a uranium enriched ore deposit on the proposed permit area known as the Dewey-Burdock project. The project is...

Enhancing the Solution of Large Monitoring Network Design Problems Using a New Epsilon-Dominance Hierarchical Bayesian Optimization Algorithm
Designing long-term monitoring (LTM) networks for contaminated groundwater is a challenging problem that has long been recognized to suffer from the curse of dimensionality. LTM design...

Summary of Approaches for Estimating Playa Lake Flooding
Playa, or terminal, lakes are common in semi- and arid environments; and their characteristic level, hard, and usually dry surfaces make them ideal for airports, as they are used in the...

Remediation System Optimization with Alternatives
This work applies the enhanced multi-objective robust genetic algorithm (EMRGA) (Beckford and Chan Hilton, 2004) to Fort Ord's Site OU2 for optimal groundwater remediation under uncertainty....

Dewatering Case History in Florida
(Originally published in Journal of the Construction Division, 1974, 100(3), 377-393.)...

Evaluation of Geopier Rammed Aggregate Piers by Geopier Foundation Company
Final Report
Prepared by the Highway Innovative Technology Evaluation Center (HITEC). This report describes a HITEC evaluation designed to determine the basic capabilities...

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...

Transferring Research Into Practice
Lesson from Japan's Construction Industry: A Report by the Civil Engineering Research Foundation and Japan International Research Task Force (JTF)

A Decision Framework for Stormwater Control in Urbanized Watersheds
Historically, urban growth occurred around water bodies due to factors such as easy access to transportation, water supply, and drainage. With the expanded transportation network along...

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...

The Role of Aesthetics in Bridge Design
The role of aesthetics in current bridge design practice varies widely. Many bridgeprojects in the United States are developed without including aesthetics as one of theproject goals....

Incorporating Site Characterization Data into Contaminant Concentration Interpolations for Long-Term Monitoring Optimization
Long – term monitoring (LTM) networks are installed for groundwater remediation systems to evaluate the performance of various remediation processes and to track the variation of contaminant...

Monitoring and Quantifying Rate-Limited Mass Transfer Using Geoelectrical Measurements
Non-Fickian solute-transport behavior has been observed at research and aquifer remediationsites in diverse geologic settings. Anomalous behavior such as concentration rebound, long breakthrough...

Pioneer Square Areaways
Pioneer Square, one of the earliest neighborhoods in Seattle, is adjacent to Elliott Bay. Much ofthis part of the city originally was built on existing land that used to get flooded. When...

Optimization of Well Placement in Groundwater Long Term Monitoring Networks
Long Term Monitoring (LTM) networks play critical roles in tracking the migration of contaminants in groundwater, evaluating the efficiency of the existing remediation techniques, and...

Analytical Solutions for Coupled Reactive Transport Equations
Modeling the transport of reactive contaminants is one of the key challenges faced by groundwater engineers worldwide. Specifically, problems involving the transport of sequentially decaying...
