Physical Habitat Simulation and the Moveable Bed
One objective of an instream flow analysis is to quantify a flow that will maintain the existing channel and/or flush fine material from the bed. Five empirical approaches to determine...
Geohydrologic Considerations in Ground Water Modeling
Ground water modeling is an effective engineering and management tool for evaluating complex hydrogeologic situations in a cost effective manner. Objectives of a particular study dictate...
Obstacles to Establishing an Effective Water Resources Planning Process in Developing Countries
Four obstacles stand in the way of effective planning: lack of agreement among participants on practical operating principles; misuse of local money-making opportunities by foreign contractors...
Sedimentation at Canal In-Line Structures
This paper describes the procedures used to compute the transport capabilities of existing canals and the process for predicting sediment deposition that will occur at or near the modified...
Modeling Erosion and Sedimentation in Irrigation
Sediment yield and erosion modeling approaches for sprinkler and surface irrigation are discussed. Empirical approaches, such as the ULSE, and other regression approaches and their applicability...
Waterpower '85
The hydropower industry is making the most of new and existing hydropower facilities to increase production. The purpose of the Waterpower '85 Conference was to review what...
Production Analysis of the Cat 245 Hydraulic Hoe
The productivity of two Caterpillar model 245 hydraulic backhoe excavators was analyzed during their use on a highway construction project in September 1983. The hoes were working in a...
Low Level Artificial Intelligence and Computer Simulation to Plan and Control Earthmoving Operations
This paper describes an advanced computerized method for designing an optimized earth distribution plan for a linear earthmoving project. Modeling and computerized simulation offer a quantitative...
The Promise of Supercomputers
This paper briefly reviews the classification and general architecture of supercomputers: their capabilities, promise, current and projected limitations are considered. The author reviews...
CAPPS: Custom Architectured Parallel Processing System
CAPPS (Custom Architectured Parallel Processing System) is under development at Paragon Pacific Inc. , Torrance, CA, for the solution of computationally intensive engineering problems....
Some Applications of Fourier Series in Structural Optimization
This paper discusses the application of the method of truncated Fourier series to problems of structural optimization. It begins with a discussion of the range of the method which has...
Study of the Collapse of a Reinforced Concrete Model Structure Under Simulated Earthquake Motion
The collapse, under simulated earthquake motion, of a multistory r/c frame structure with columns flexurally weaker than beams (SBWC) is studied. A small-scale model, comprising parallel...
Microcomputer Application of the Florida Standard Urban Transportation Modeling Structure
Over the past five years the Florida Department of Transportation (FDOT), in conjunction with the twenty-one Florida Metropolitan Planning Organizations, has developed the Florida Standard...
Methods for Real-Time Control of Highway Traffic
The paper describes the development of computational strategies for demand-responsive decentralized traffic signal control. First, a Dynamic Programming procedure is developed which serves...
Fuzzy Sets Bring Ideas Into Focus
Fuzzy set theory was born out of a dissatisfaction with classical crisp sets and binary logic. Conventional computers, despite 30 years of evolution, are still rigidly precise, number...
Pipeline Frost Heave Predictions Using a 2-D Thermal Model
Chilled structures founded on initially unfrozen soils cause a zone or 'bulb' of frost to develop with time. This time period may be of seasonal duration, as...
Nonlinear Analytical Models for Interfacial Plug Stresses in Creeping Salt Formation
Analytical and numerical simulation models are presented which predict the nonlinear time dependent behavior of an expanding plug in a creeping environment heavily dependent on the storage...
Some Recent Advances in Automatic Mesh Generation
The establishment of automated finite element modeling procedures must begin with the development of automatic mesh generators capable of producing a valid finite element mesh for any...
Modern Methods for Automatic FE Mesh Generation
An overview of the various Finite Element mesh generation techniques is presented. Since most automatic FE Mesh Generation techniques read in geometry of the object and create meshes on...
