This volume contains the papers presented in 21 sessions of the 1989 Structures Congress held in San Francisco. The papers cover a wide range of topics including types of construction...
Structural Materials
This volume of Structural Materials contains papers from 12 sessions of the 7th Structures Congress held in San Francisco on May 1-5, 1989. The sessions cover a very broad range of topics...
Interactive Aircraft Section Calculations for Drag
Large interactive computer programs are being called upon with increasing frequency for the preliminary and conceptual design of aircraft. One drag component which can be estimated at...
Computerized Dynamic Human Factors Mannequins Assess and Create Products and Environments for an Aging Population
A PC-based human factors symbol library helps make designs accessible to a broad populace. The system and research results described were developed in three phases. Knowing that in order...
Constraint Based Design from Research into the Classroom
Design is constraint oriented; much of the design process involves the recognition, formulation and satisfaction of constraints. Constraints are continually being added, deleted and modified...
Ozonation of a Biorefractory Organic Compound
This study involved determination of the degradation of chlorendic acid due to ozonation, possible biodegradation of the resultant products, and possible toxicity of the resultant products....
Using Borosilicate Glass as a HLW Storage Medium
There is growing concern over the quality of present high level waste management techniques. Instances of nuclear accidents and contamination at nuclear waste sites in the United States...
Radon Resistant New Construction Practices
This paper highlights the basic principles for building radon-resistant houses and it groups the construction techniques into four categories, i.e., the barrier approach, soil ventilation...
Preacquisition Environmental Site Assessments: Avoiding Common Errors and Omissions
The 1986 Superfund Amendments and Reauthorization Act (SARA) established an 'innocent-purchaser' defense to environmental liability from ownership of contaminated...
Trio of Microcomputer Models for Organic Chemical Transport in Rivers
Three microcomputer models have been jointly developed to provide tools to simulate the fate of organic chemicals in river systems. The three models offer a range of complexities and data...
Stabilization of Critical Enclosed Natural Draft Ground Flares
This paper presents the results of an investigation evaluating the causes of and implementing a cost effective solution to combustion driven oscillations in six large natural draft flares....
Water Quality Criteria for Irrigation
An assessment of irrigation water quality for the concentration of inorganic constituents should consider crop sensitivities, soil properties, such as hydraulic conductivity, reactions...
State Financing of Soil Conservation Programs
Federal financial incentives to implement conservation programs under traditional programs probably will not increase. Any increases in present financial incentives and new incentive alternatives...
Dynamic Modeling and Control Optimization in An Urban Area?A Case Study
The procedures adopted to achieve improved economic operation of the water supply and distribution system serving the town of Wolverhampton (UK) are described. An outline description is...
Channel Routing for Improved Flood Control
Lake Wappapello, located on the St. Francis River in southeastern Missouri, is operated by the St. Louis District (SLD) Corps of Engineers for purposes of flood control and recreation....
Use of Probabilistic Constraints in Reservoir Operation Policies With Sampling Stochastic Dynamic Programming
The role of mathematical simulation and optimization models in hydropower planning at Pacific Gas and Electric Company is discussed, and some of the models are described. Applications...
Application of Principal-Component Analysis to Long-Term Reservoir Management
Determining the optimal long-term operating policy of a multireservoir power system requires solution of a stochastic nonlinear programming problem. The paper presents a very efficient...
Self-Accelerated Turbidity Current Prediction Based Upon Dynamic Turbulence Models
The structure of a self-accelerated turbidity current appears to be significantly better predicted by a dynamic Reynolds stress turbulence model than by one- and two- equation models....
Modeling Sediment Transport in Rectangular Ducts with a Two-Equation Model of Turbulence
The paper deals with the application of a two-equation model of turbulence to the calculation of flows in rectangular ducts. A non-linear relationship is used to link the Reynolds stresses...
Towards a Distinct Treatment of Incipient Motion for Bed Forms of Low Regime
The principle methods for estimating the incipient particle motion on developed bed forms in the lower regime are compared with each other. Usually only a part of the total wall shear...
