Hydrologic Modeling for Decision-Makers
All Properties within a community benefit from having an adequate system of storm drainage facilities and controls. Such benefits include: reduction of hazards to property and life resulting...
The Hydrology of Urban Runoff Quality Management
Recent regulatory requirements to reduce pollutant discharges from municipal storm sewer systems have intensified the need for approaches to developing design parameters, such as the selection...
A PC Method to Compile Land Use Data for Hydrology
A computerized method for compiling and reducing land use data for hydrologic computer model simulation was developed. The technique was developed for use on an IBM compatible PC. The...
Effect of Storm Distribution on Watershed Stormwater Management
This paper presents a case study illustrating the effect of the selection of rainfall distribution pattern upon the ability of a calibrated rainfall-runoff simulation model to replicate...
A Storm Water Management Model for Grand Rapids, Michigan
In 1989, the City of Grand Rapids, Michigan, engaged Black & Veatch to conduct a comprehensive study of its combined sewer system with two primary objectives: (1) to relieve basement...
Evaluation of the Feasibility to Retrofit Stormwater Control Facilities to Improve Pollutant Removal Performance
This paper presents the results of an analysis that was performed to predict the efficiency of removal for suspended sediments in storm runoff under existing conditions and under several...
Diagnostic Options for Pipeline Rehabilitation
The various diagnostic options utilized for solving pipeline problems/failures continue to increase at a very rapid pace. Field reconnaisance and/or man-entry of pipelines is becoming...
The Danby Pipe Renovation System
This paper describes a pipe renovation system and its structural characteristics which is cost effective and technically suitable in all sizes of pipe from 8 inches (200 mm) to the largest...
Rehabilitation of Urban Pipelines
The City of Los Angeles is embarking on a replacement and rehabilitation program for the distressed portions of its sanitary sewer system which will cost in the hundreds of millions of...
Development of an Optimal Strategy for Storm Sewer Infrastructure Rehabilitation
Rehabilitation of the nation's infrastructure will require a significant expenditure of public funds in the near future. Efficient management of these funds will require tools...
Reliability Consideration in Capital Improvement Programs
This paper shows an application of network reliability modeling in water supply capital improvement programs. The proposed approach consists of combining geometrical and structural properties...
Rebuilding Buried Pipelines Without Digging
Advances and refinements in trenchless reconstruction technologies now permit system rebuilding of gravity and low pressure pipelines without excavation. Through the use of cured-in-place...
1991 Update on Sanitary Sewer Rehabilitation Metropolitan Chicago
The Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) owns intercepting sewers and seven water reclamation plants, but 125 local communities own the local sewers which...
Water Distribution Infrastructure Analysis
Water distribution systems in many older cities of the United States need rehabilitation. Because the rehabilitation costs of the nation's water systems will involve billions...
Los Angeles' Pipeline Rehabilitation Program
One-third of the City of Los Angeles' 7,000 mile water distribution system had been installed without internal protection. The Water System is aiming for a 900,000 foot per...
Optimization Model for the Control of Saltwater Intrusion
An optimization model is presented for the control of saltwater intrusion in the Jakarta groundwater basin. A quasi three dimensional, finite difference simulation model is used to predict...
Reliability of Model Prediction for Pump and Treat Strategies
For the remediation of aqueous phase plumes extending over large areas simulation models are often used to predict the response of the aquifer system and the contaminant concentrations...
Methods for Designing Hydraulic Aquifer Remediation Techniques
This paper reports on recent research to develop methods for accommodating uncertainty in designing hydraulic remediation systems for contaminated aquifers. The methods rely respectively...
Field Investigation for Leachate Flow in a Landfill
Field investigation for leachate flow was done for the Fresh Kills landfill at Staten Island, New York. The leachate monitoring program included data collection from the field for a six...
