Hierarchical Substructuring for Adaptive Analysis
An algorithm for the automatic generation, from solid models, of finite element meshes organized as spatially addressable quaternary trees (for 2-D analysis) or octal trees (for 3-D analysis)...
Real Time Data Acquisition in Structural Testing
The process of data collection in real time for structural engineering can be generalized into a process called the real time sequence. The sequence has three major phases: preliminary...
Estuarine Hydrodynamic Modeling on MicroComputers
The program for a two dimensional finite difference estuarine model was adapted for use on a modified IBM-PC/XT microcomputer. Commercially available hardware and supporting software were...
Groundwater Modeling: Selection of Computing Systems
Results are presented for ten microcomputer systems evaluated with respect to system performance in solving a test case three-dimensional groundwater flow problem. The model used was the...
Improved Urban Traffic Flow Through Signal Re-timing?California Experience
The California Energy Commission (CEC) has initiated a new program to re-time all of the 20,000 interconnected traffic signals in the state, the first of its kind in the United States....
The Electronic Road Pricing System in Hong Kong
This paper addresses the traffic congestion problem and issues relating to the experiment of the world's first pilot scheme on Electronic Road Pricing System in Hong Kong....
Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...
Three-Dimensional Analysis of an Artificial Island
A nonlinear, finite element analysis has been carried out to investigate the influence of three-dimensional loading and geometry on deformation and failure of an artificial island. The...
Negatively Buoyant Flow in a Diverging Channel
Negatively buoyant (plunging) flow from a horizontal, constant width channel into a diverging channel has been studied in the laboratory. The study was undertaken to provide information...
Local Pressure in Ice-Structure Interactions
Two models for the determination of local pressures during marine ice or iceberg collisions with bottom-founded structures are presented. The first model is a two-dimensional analytical...
Proportional Weirs for Stormwater Pond Outlets
Many jurisdictions mandate that new developments must not cause runoff to flow downstream, during and after rainfalls, at rates higher than preconstruction. A common for controlling runoff...
Simulation of Hillslope Hydrologic Response to Snowmelt in Southwestern Idaho
A two-dimensional, variably saturated porous media flow model was applied to vertical hillslope cross section on a first order study basin in southwestern Idaho. The dominant source of...
The Role of Multiple Level Hydrologic Analysis in Watershed Management?A Case Study in Trinidad
An accurate estimation of peak flood flows and its correlation with existing and future land use are basic requirements for the scientific management of Watersheds. An accurate estimation...
Prediction of Soil Water Properties for Hydrologic Modeling
Water flow in soils can be characterized for many boundary and initial conditions by solving governing differential equations. Thus, a physically consistent means of quantifying water...
Source Area Variability During Peakflow: A Function of Antecedent Soil Moisture Content
An attempt was made to identify the source areas contributing to peakflow and to quantify the relative importance of each source area under various antecedent soil moisture (ASM) conditions....
A Systematic Evaluation of Hillslope Subsurface Flow: The Effects of Slope Angle and Soil Parameter Variation
A two-dimensional finite element variably saturated flow model is used in conjunction with an automatic mesh generating scheme to simulate hillslope subsurface flow. Slopes from 2% to...
Seepage in the Unsaturated Zone: A Review
This paper briefly reviews the procedures whereby the seepage rate, depth of penetration of nonreactive pollutants, and the depth of the wetting front can be calculated when the assumption...
Use of Asphalt in Treatment of Dam Foundation Leakage, Stewartsville Dam
This paper presents the recent development and application of a hot asphalt grouting technique used to stop a 5,000 Imperial Gallons Per Minute (IGPM) (22,000 lpm) dam leakage under full...
Computer Applications in Grouting
The first use of computers during foundation grouting was tried by the Bureau of Reclamation on Ridgeway Dam in Colorado. It was very useful in monitoring real time down hole conditions...
