Evaluation of a Soil Vapor Extraction System: A Post-Audit Assessment
(No paper) Numerous sites contaminated with volatile organic compounds (VOC) have implemented soil vapor extraction (SVE) systems to remediate the unsaturated zone. The SVE systems have...
Simplification of Detailed Models of Water Distribution Systems Obtained from GIS Systems
For a long time simplified models have been used to simulate the behaviour of large water distribution networks. Often, simplification has been carried out by removing small diameter pipes...
Urban Runoff Toxicity
Toxicity is controlled by the magnitude/concentration of the contaminant produced in an exposure, the duration of the exposure, and the frequency with which exposures are repeated. When...
Integration of SWMM and ARCVIEW GIS for Interactive Decision Support
(No paper) This paper covers the integration of the EPA SWMM runoff model and ESRI's ArcView GIS for utilization by the City of Phoenix for decision support concerning land use changes...
Impacts of CSO Swirl Concentrator on Dissolved Oxygen Concentrations in the Anacostia River
Purpose: To assess impacts of the CSO control, two continuous monitoring stations were located upstream and downstream from the CSO outfall. The monitors recorded dissolved oxygen (DO),...
Friction Factor Choice in Hydraulic Simulation Models: Does It Matter?
(no paper) To model water distribution systems using computer hydraulic simulation, a user is required to select a form of head loss-flow relationship for each pipe in the network. The...
Selection of an Optimal Ecosystem Restoration Plan: Decision-Making Criteria in the Planning Process
(No paper) This paper explores various decision criteria for restoration projects and how they may be modeled with existing decision models. Cost-effectiveness, incremental cost analyses,...
Interactive Flood Response Plans: Internet/Intranet Formats with National Implications
