Computer Use in Structural Analysis
Acquisition of computer hardware and software in order to establish distributed processing and a local area network at the Air Force Weapons Lab has greatly streamlined two structural...
Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...
Wave Runup Around Conical Structures
A variety of conical structures have been proposed for use in the Arctic environment, primarily because the inclined surface of such a structure gives rise to reduced ice loads associated...
Predicted and Measured Performance of a Foundation
The predicted and measured short term foundation behavior of a 28 story building in downtown San Antonio, Texas is reported. The soil is a stiff to hard clay and clay shale. The design...
Simulation of Airborne Snow Water Equivalent Measurement Errors Made over a Forest Environment
The Office of Hydrology of the National Weather Service has developed and maintains an operational Airborne Gamma Radiation Snow Survey Program in the upper Midwest (Peck, et al. , 1980)....
Characterization of Variable Soil-Water Properties
Hydraulic conductivity, water retention, soil bulk density, and clay content were analyzed on undisturbed soil cores obtained from different depths at sixteen locations in a 24 acre watershed....
Modelling of the Fracture Process Zone in Rock
There are a number of situations in the fracture mechanics of rock in which linear elastic fracture mechanics (LEFM) concepts are inapplicable or insufficient. Two such situations are...
Bond Stress of Embedded Steel Shapes in Concrete
This paper describes an investigation into the bond stress developed between steel shapes and reinforced concrete when the concrete is lightly stressed. A brief discussion of previous...
Storage Projection for Reservoir Systems
Two methods are studied for determining the probability distribution of future levels of storage in a reservoir system: transient analysis and Gould's probability matrix method....
Modeling a Water Distribution System
Problems encountered in modeling the water distribution system for the City of Norwich, NY are discussed and the procedures used to solve each problem are described. The interpretation...
State-of-the-Art Pipe Network Optimization
Within the next decade water distribution system optimization models should become everyday tools of practicing engineers. This paper examines existing models and discusses some of the...
Pipe Network Optimization by Enumeration
The paper describes a procedure for the optimization of pipe networks which is executed entirely in the discrete pipe size/cost domain. The technique is based on exhaustive enumeration....
Computer Usage in Obtaining Alternate Optimal Solutions for Water Resources Optimization Problems
In this paper, alternate optimal solutions of a few example linear programming problems are obtained by using a computer routine developed for the purpose. The routine is capable of generating...
Use of a Two-Dimensional Flow Model to Quantify Aquatic Habitat
This paper describes the use of a numerical two-dimensional flow model to evaluate the impacts of potential hydropower retrofits on downstream flow distributions at Lock and Dam No. 8...
Conjunctive Use/Sustained Groundwater Yield Design
Assuring the sustained availability of groundwater from all parts of an aquifer system is analagous to assuring that the potentiometric surface does not change over the long term. Such...
A Physical-Chemical Interpretation of Mean and Extreme Values in Acid Precipitation
A physical-chemical model is used for the interpretation of mean and extreme concentrations in acid precipitation. Chemical concentration frequency distributions tend to be skewed, as...
Benefits of Particle Size Management for Biological Wastewater Treatment
Particle size distributions in wastewater can be used to monitor and model the transformations that occur during wastewater treatment processes. Typical size distributions of organic contaminants...
Oil Spill Detection by NOAA/AVHRR on Persian Gulf
An area of oil spills on the Persian Gulf was detected by the thermal-infrared channels of Advanced Very High Resolution Radiometer (AVHRR) on NOAA-7. AVHRR gives the temperatures of the...
Integrated Hydrothermodynamic Study of Browns Ferry Nuclear Plant
The results of hydrothermodynamic analyses and computer models discussed in previous papers are combined to present an integrated study supporting a request for alternative thermal limits...
Boundary Shear Stress in a Meandering Channel
Longitudinal and transverse velocity, bed shear, and water surface elevation were studied in a fixed-bed, meandering, laboratory channel with naturally varying, non-prismatic cross sectional...
