Expert System Tools for Civil Engineering Applications
Expert system software tools have played a major role in expediting program development. Some problems should not and possibly cannot be solved by current expert system technology. For...
Delineation Effectiveness for Alcohol Involved Accidents
The approach to the problem of the alcohol impaired drivers to date has been directed at driver education and increased police enforcement. A complementary and parallel approach is presented...
Efficiency Gains Using Micro Computers in Marina Design Engagements
This paper addresses improved efficiency in marina design engagements using low cost micro computers and low cost software. From the preparation of an offer for service, through design,...
Recent Trends and Advances in Bulk Cargo Unloading
The progress in loading of bulk cargo into ships has matched the advances in ships' size. The same could not be said for getting bulk material out of the hold of a ship, in...
Improving Maintenance Performance
This discussion concerns Maintenance Management concepts that emphasize how the human element among Port personnel can be organized and efforts channeled so as to: increase the actual...
Computer Pricing Practices
Civil engineers have become increasingly involved with the use of computers to help solve engineering problems. Many problems that previously could be solved only approximately, or that...
Treatment Facilities and Costs for the Removal of Radon from Ground Water Supplies
Two methods for removal of Radon from drinking water are considered: activated carbon adsorption and packed tower aeration. Although both granular activated carbon (GAC) and packed tower...
Current Status of Flue GasDesulfurization in the United States
Flue gas desulfurization (FGD) systems have been in existence in the United States for only 17 years but they have made a tremendous impact in the operation of utility plants. At present,...
Sea Level Rise and Coastal Stormwater Drainage
Global sea level rise as a result of the greenhouse effect and the past trend and future projection on the rise are discussed. Potential problems associated with coastal stormwater drainage...
Optimizing Drain Spacing and Depth Using Steady State Equations
A method is developed for minimizing the total cost of establishing relief drains by choosing appropriate depth and spacing of the drains. Solution graphs are presented for a wide range...
Making Water System Rehabilitation Decisions
Making decisions regarding water distribution systems has always involved a great deal of judgment due to the complexity of the decisions involved. This paper presents a framework for...
Water Infrastructure Maintenance Needs?A Case Study
Adoption of measures to prevent loss of water in many cases is cost-effective. In order to illustrate the magnitude of infrastructure problems of large cities, a test case infrastructure...
Transferring Conserved Water
The proposal to transfer water salvaged by water conservation programs from one area to another is a new concept. Imperial Irrigation District (District), located in the southeast portion...
Sediment and Erosion Control Implementation: An Overview
The responsibilities of the federal, state and local governments in sediment and erosion control are reviewed. The effectiveness of cost-shared and non-cost-shared technical assistance...
Hydraulic Reliability of Urban Water Distribution Systems
Conventional planning and design approaches for urban water distribution systems consist of trial and error procedures to select piping network configurations, pipe sizes, storage capacities...
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...
Integrated Wastewater and Sludge Treatment in a Tree Farm
A system which integrates land treatment of wastewater following primary sedimentation with tree production and sludge composting was evaluated for its land requirements, costs, and energy...
Computer Aided Drafting in the Water Resources Environment
The movement from traditional mechanical drafting to computer aided drafting in the small consulting business/research environment while necessary from the viewpoint of productivity and...
Water System Reliability?Balance of Cost and Risk
Reliability of water distribution systems to perform adequately during stress situations is dependent both on operation/maintenance preparedness as well as the limitations of the physical...
Benefit-Cost Evaluation of Minimum Instream Flows
In many cases, determinations of minimum desirable instream flows (MIF) are made without full consideration of economic costs and benefits. Benefits are frequently quantified in nonmonetary...
