Performance of a Deterministic Storm Runoff Model
The paper discusses model comparisons based on a Tulsa, Oklahoma, case study. Modeling strategies were explored, four of which were modeled in detail because of the extremes in range of...
Port Infrastructure Program in Mexico
In Mexico the policies, guidelines, goals and methodologies refering to transport, are the responsibility of the 'Secretaria de Comunicaciones y Transportes'...
Modeling Reliability in Water Distribution Network Design
The component failures in a water distribution system include pipe breaks, pump failures, valve failures, storage malfunctions, etc. The reliability of these components has an effect upon...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
A New Methodology for Modelling Water Pipe Breaks
A new methodology for modelling breaks in large diameter cast-iron water pipes is proposed. The need to consider two separate stages of deterioration (early stages with fewer breaks and...
Taming a Pipe Network Analysis Computer Program
The use of a conventional network analysis computer program as an effective evaluation tool for routine operation of an existing water distribution system has several practical limitations...
Guidelines for Maintenance of Aging Water Pipes
Break failure patterns are investigated by applying a new methodology based on Proportional hazards and Poisson-type models. Application on two water distribution systems of North-Eastern...
Microtunneling: No Pipe Dream
Microtunneling machines developed in Japan and Germany can help install pipes, ducts and cables without disrupting urban activities at street level. A microtunnel is defined as having...
Seismic Response of Pipes Supported on Complex Frames
Analytical approaches and modeling techniques used to calculate seismic responses of piping systems, supported on complex open-frame structures, are evaluated. Seismic responses are obtained...
Structural Monitoring Concepts for Arctic Pipelines
Terrain instabilities producing differential soil movements are the predominant features affecting the structural integrity and design of buried pipeline systems in the arctic. Current...
Water System Data Base for Naples, Florida
Boyle Engineering Corporation has developed a comprehensive database technique using its Intergraph Computer-Aided Design and Drafting (CADD) system to assist in the computer modeling...
Advanced Microcomputer Simulation for Construction Managers
The concept of simulation allows the analysis of complex and dynamic systems such as those encountered in construction operations. In particular, the technology orientation of construction...
The Local Area Network in an Engineering Office
During the past several years, the St. Paul District, U. S. Army Corps of Engineers, has purchased a variety of computer equipment. In late 1985, the District solved the problem of communication...
Commercially Available Workstation Networks
Twelve commercially available local area networks are compared, transmitting variously over optical fiber, twisted pair and cable. Throughput, tunability, cost and ease of use are discussed,...
An Interactive Model for Project Planning and Scheduling
This paper presents the development and use of an interactive, microcomputer-based model for project planning and scheduling. The model is general enough to handle both deterministic (CPM-based)...
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...
Microcomputer Construction Operations Simulation
This paper summarizes the current status of an ongoing research project whose objective is to collect time data from videotapes of field construction operations and use the data as input...
Best Management Practices Overview
In the general list of best management practices for stormwater control, many practices are currently being used. On-line retention and detention ponds are used frequently and their importance...
Cut-and-Fill Becomes Cut-and-Drain
The U.S. Navy's facility in Subic Bay, Philippines, is in a mountainous area which experiences 182 inches of rain per year. These factors plus weak soil, made necessary an...
Cleaning the Nut Island Outfalls
As an early component of a comprehensive program to reduce pollution in Boston Harbor, two 80-year-old cast-iron outfalls, each 60 inches in diameter and a mile long were cleaned in a...
