Analysis of Thermal Scanning Imagery to Investigate Point Inflows Into Surface Water Bodies
Using a modified technique of thermal infrared remote sensing, physical sampling, and data analysis (graphical and geostatistical) locating a small inflow to a lake was possible. Thermal...
Municipal GIS Applications Utilizing Vector and Raster Software on Personal Computers
Confronted by increasingly tight budgetary constraints, combined with the expensive computer processing hardware typically required by a GIS, smaller engineering firms and local governments...
Low Stream Flow Frequency Analysis with Ordinary and Tobit Regression
In order to estimate the low-flow quantiles at ungaged sites, it is necessary to estimate low-flow quantiles at gaged sites. Two linear regression methods, denoted NR and NE, are compared...
Guidelines for Water Resource Models Development and Use
Water resources literature suggests that computer based models have the potential to provide useful information in facilitating water resources decision making process. Therefore, continuous...
Management and Statistical Analysis of Groundwater Monitoring Data at Solid Waste Landfills
Solid waste landfills in Ohio and Michigan, as in many states, are required to have monitoring wells. Groundwater samples from these wells are analyzed to determine if leachate from the...
Reservoir Operation Analysis with the PC
Information for reservoir water-supply planning is available from an interactive PC-DOS-based program. With this program, the user controls the sequence of data preparation and simulation...
Wave Motion in Aerated Rubble Mounds
Experimental investigations were undertaken to study the effect of air entrainment on wave motion in rubble mounds. The study is aimed at the understanding of the processes associated...
New Jersey Department of Transportation Bridge Scour Evaluation Program
The New Jersey Department of Transportation's (NJDOT's) newly initiated bridge scour investigation program will assess the vulnerability to failure by scour of...
Introduction to Multi Criterion Methods and Selected Software
Water resources and environmental managers face a difficult task of managing water resources systems to meet an increasing array of objectives. Often the various objectives are non-commensurable...
Modeling 70,000 Feet of Interceptor for Aurora, CO
During preliminary design for the City of Aurora's Tollgate Creek Interceptor Sewer Improvements, the authors modeled over 70,000 linear feet of interceptor for both present...
Automated Sensitivity Analysis for FORTRAN Models
For complex computer models used in engineering design and assessment, a cost-efficient procedure for identifying the parameters that are important to a given model prediction is a necessity....
Analysis of 1989 Floods in Harris County, Texas
On May 17 and 18, 1989, a severe thunderstorm stalled over Harris County, Texas, producing over fourteen inches of rain in a twenty-one hour period. Slightly more than one month later...
Use of Models in Water Resource Systems: CRSS Experience
The Colorado River Simulation System (CRSS) is an in-house governmental computer-based model designed to be used as a decision support tool in performing long and mid range planning and...
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...
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...
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...
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...
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...
Statistical Analysis of Ground Water Quality Data
The Resource Conservation and Recovery Act (RCRA) requires owners and operators of hazardous waste facilities to utilize design features and control measures that prevent the release of...
Computer Modeling as a Tool for Selecting Appropriate Air Valves for Pipeline Surge Protection
Waterhammer in water or wastewater pipelines is caused by events such as a pump power failure and can have potentially damaging effects on the pipeline or pipeline hardware. In particular,...
