This paper describes one tool that might be part of a package to assist a design engineer in sizing pipes, determining ideal locations for booster pumps and their heads, determining heads...
Computerized Design and Selection of Pumping Systems
Three computer models have been applied in the evaluation, design and selection of a high-lift pump station upgrading program developed for the City of Poughkeepsie, New York. The three...
Optimizing Nonpoint Source Pollution Reduction Costs
This study demonstrates diminishing marginal returns for spending to reduce nonpoint source pollution in Hampton, Virginia. A linear optimization program selected the best combination...
Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...
Apportionment of Costs for Multi-Party Cleanups
A rational model was developed for allocating remedial response costs among potentially responsible parties involved in clean up of abandoned waste sites. The model takes into consideration...
True Cost Comparison of Landfilling and Incineration of Hazardous Wastes
An analysis of the 'true' costs of a series of discrete model situations representing hazardous waste management by landfilling and incineration was conducted....
Saving Time and Money with Archaeology
In the past 20 years, archaeology has become a necessary part of many engineering projects. However, this aspect of a project is often regarded as an obstacle in terms of costs and time....
Land Treatment of Refinery Wastes
The authors discuss: waste characteristics; land treatment; and cost comparison with incineration....
Operations, Maintenance & Cost Comparisons of Three Dewatering Devices
The Metropolitan Waste Control Commission's Wastewater Treatment Plant in Minneapolis/St. Paul has demonstrated that two new innovative sludge dewatering pocesses, namely,...
Denver's Dual Utilization Sludge Management Plan
The Metropolitan Denver Sewage Disposal District No. 1 (District) has adopted a Dual Utilization approach to sludge management. This technique uses composting during periods of inclement...
Proposal for Funding Water Conservation Programs
Programs have been identified which appear to have the potential to conserve significant amounts of water within a large irrigated agricultural area. Losses such as canal seepage, operational...
Economics of Ditch Maintenance in Northwestern Ohio
A history of drainage and settlement in the Black Swamp of Northwestern Ohio is presented. The Ohio Ditch Law and county ditch maintenance program is explained. An economic comparison...
Innovative Management in a Period of Austerity: The Glamorgan Heritage Cost Experience in the U.K.
Restraint in UK economic growth gave rise to a new countryside management approach which was non-statutory, dependent upon voluntary agreements. In essence the land remains in private...
Inspection/Condition Analyses of Large Underground Pipelines
Inspection/Condition Analyses of Underground Pipelines (sewers and conduits) will be a necessary function of the pipeline Owner/Operator. The Condition Analyses and Inspection phases are...
Hydropower Surveys with Microcomputers
A microcomputer program, HYFEAS, has been written in BASIC for use in pre-feasibility assessments of a given site. HYFEAS uses a flow duration curve, headwater and tailwater curves, information...
Open Channel Flowrate Measurement Using Multipath Acoustic Flowmeters
Recent acoustic flowmeter developments have improved the applicability and accuracy of the multipath acoustic measurement technique. Accuracy, hardware cost and calibration cost can be...
Application of a Detachable Gondola Ropeway in an Urban Transport Environment: New Orleans, La.
The first United States application of the detachable, monocable, gondola ropeway system as an urban transportation system is presented. The system is the Mississippi Aerial River Transit...
Market for AGT and its Implication for Needed R&D
This paper reviews the present market for automated-type transit systems, outlines the attributes required to satisfy and expand this market, and identifies deficiencies in existing Automated...
Applications and Benefits of Accelerating Walkway Systems
A number of studies have shown that many persons resist walking, and might be willing to pay as much as 25 to 50 cents per minute to avoid walking. A new form of urban transport - Accelerating...
Parametric Analysis of APM Operational Components: Stopping Policy, Stations and Headway
This study examines generically relationships among the three parameters using a single line transit system. Optimization models are developed to determine the optimum number of stops...
