Integration of SCADA and GIS Technologies in Jefferson Parish, Louisiana
Due to its physiographic setting in the delta region of the Mississippi River, a majority of the inhabited lands in Jefferson Parish, Louisiana are below local mean sea level and much...
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...
Sediment Impediment to Boat Launching at Miller Park, City of Avon Lake, Ohio
In 1987 a boat launching facility was constructed at Miller Park, in the City of Avon Lake, Lorain County, Ohio (Figure 1). There have been problems with sediment buildup ever since it...
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...
Urban Storm Drainage Design Hydraulic Principles
Chapter 6 of the manual on Design and Construction of Urban Storm Water Management Systems discusses the hydraulic principles and equations under which drainage system structures must...
A Conceptual Basis for Developing Model State Water Codes
The crafting of model state water codes must proceed out of the recognition that there are two prevailing philosophies under which resources are allocated. These contrasting systems both...
Drainage Design Criteria: Too Restricted? Too Broad? Too Outdated?
Should drainage design policies be more flexible, leaving the field more open to engineering judgment? Are some policies too loose or broad? Should design criteria more closely reflect...
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...
Applying Benefits-to-Costs Analysis for Stormwater Improvement Projects
Benefit-to-cost analyses provide a measure of evaluation for the justification, selection, and prioritization of stormwater improvement projects. Facing increased competition for tax dollars...
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...
