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...
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...
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...
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...
Field Data-Gathering: Critical First Step for a GIS
Gathering data in the field is one of the first major tasks required for developing a geographic information system (GIS) or automated mapping/facilities management (AM/FM) system. This...
A Visualization Toolkit for Fluid Mechanics

A Substructuring Algorithm for Analysis and Optimization of Large Structures on Parallel Machines
An efficient substructuring algorithm is presented for analysis and optimization of frame structures on parallel machines. The underlying concept is to pre-process the input data in such...
A Kinematic Hardening and Softening Model of Concrete
In the present paper, a new loading surface calibrated by several typical uni- and multi-axial test curves is proposed. Following the associated flow rule, a relatively simple constitutive...
Extracting Dynamics from Ocean Wave Time Series Data
Recent developments in chaotic dynamics have indicated that qualitative information of a dynamical system can be extracted from the observation of a single time series as the time series...
Response Triscpectrum for a Yielding Structure
Simulation is used to obtain information about non-Gaussian aspects of the absolute response acceleration of a bilinear hysteretic oscillator with an excitation which is Gaussian white...
Methodology for Developing an Engineering Solution for Web Crippling
This paper describes the methodology used to develop an engineering solution for web crippling of aluminum trapezoidal sections. The development has two steps. The functional form for...
Acoustic Emission Source Locations in Concrete
The location of acoustic emission (AE) sources can potentially provide information on the fracture process zone in brittle materials such as concrete. Typical AE experiments generate very...
