Computer Modelling of Concrete Cover Effect on the Behavior of Fiber Concrete Subjected to Monotonic Pullout
The objective of this paper is to evaluate the concrete cover effect on the bond behavior of bars embedded in normal and fiber reinforced concrete. Nonlinear finite element analysis is...

Finite Element Analysis and Design of Plywood Shear Walls
An integrated procedure for the analysis and design of rectangular plywood shear walls is presented and illustrated. The analysis is done using an in-house finite element program with...

A Parallel Fron Large-Scale Stris
A methodology for large-scale structural analysis using a parallel frontal solution algorithm is developed and implemented on the Alliant FX/80 Multiple Instructions Multiple Data (MIMD)...

Parallel Preconditioned Conjugate Gradient Methods for Structural Analysis Problems with Multiple Loadings
This paper describes the use of conjugate gradient method for finite element problems with multiple loading cases. Specifically, we introduce a modified conjugate gradient method for the...

A GIS for the Louisiana Coastal Zone
The U. S. Army Engineer District, New Orleans is responsible for collecting, interpreting, and publishing large amounts of data related to engineering geology, subsidence, and land loss...

GIS Applications Floodplain Reconnaissance Studies
U.S. Army Engineer District, New Orleans (NOD) employed a Geographic Information System (GIS) to support a flood plain management Reconnaissance Study. The study region encompassed the...

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...

Application of Kalman Filtering to Groundwater Flow in Finite Heterogeneous Aquifers
A stochastically based methodology using Kalman filtering is presented for the optimal estimation of hydraulic properties in finite heterogeneous aquifers. This is achieved by applying...

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...

Central Valley Groundwater and Surface Water Model: A Conjunctive Use Planning Tool
A three dimensional finite element groundwater simulation model is integrated with a surface water simulation model to evaluate the conjunctive use feasibility for a specific area. The...

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....
