Water Use Pattern of Residential and Commercial Customers
The availability of the Automatic Meter Reading (AMR) devices make it possible to read a large number of meters in a short period of time. Through the use of AMR, we monitored weekly water...
Low Flush Plumbing Fixtures and Wastewater Systems
The significance of low flush plumbing fixtures on the wastewater collection and treatment system serving a small community has been determined. Among the concerns studied were: functional...
Use of a Statistical Model to Forecast Future Wastewater Flows
Future wastewater flows are generally predicted based upon an assumed rate of population and industry growth within a treatment facility's area of influence. In a community with limited...
Seasonal Rates?The Pros and Cons: A Case Study
The Spring Valley Water Company, an investor owned water utility serving over 58,000 customers in Rockland County, New York, implemented a seasonal differential rate structure in 1980....
Optimal State Feedback Estimation in Groundwater: Application to Leaky Aquifers
The problem of groundwater flow in leaky aquifer is looked at from a stochastic point of view. Optimal estimation of hydraulic heads are achieved using Kalman filtering. The Kalman filtering...
Flow Investigation for Landfill Leachate
A two-dimensional unsteady-state moisture flow model has been developed in order to describe the leachate flow process in a landfill. The unsteady variation of leachate mound head has...
Urban Stormwater Runoff Control System?Village of Skokie, Illinois
Combined sewer systems in many communities lack the capacity to convey stormwater runoff from even small to moderate storm. This inadequate capacity, in turn, causes basement flooding...
Receiving Water Quality Bases for Evaluating CSO Control Alternatives
Waters receiving combined sewer overflow loadings in the vicinity of Bangor, Maine include the Kenduskeag Stream and the Penobscot River. The city's facilities planning effort was performed...
When the Well Runs Dry Paying for Storm Water
Much will be said during this conference about the need for various structural and nonstructural approaches toward mitigating problems related to storm water quality and quantity management....
Continuous Simulation Modeling for Sewer Systems
The peaking-factor method of sanitary sewer design was developed to simplify the calculations in determining design flow rates. This method of analysis is conservative to the point that...
Managing Stormwater with a Microcontroller Operated System
Concepts of managing urban stormwater runoff with a microcontroller operated flow control system are presented. The microcontroller system allows flexible and precise flow control from...
A Raft System for Large River Hydraulic Measurements
Collection of hydraulic data in large rivers is a difficult, time consuming, and occasionally perilous task. High water velocities, considerable depths, and wide channels present obstacles...
Urban Runoff and the Environment
This paper discusses complex water quality problems, including management of urban runoff. Mathematical modelling is used to asses runoff quantity and quality. Environmental impact...
Marketing Strategies for Engineers
Engineers face the constant challenge of informing the public and their potential users of their capabilities and the benefits that may be achieved from their services.
The 3D Approach to Design
Designing directly in three dimensions, including integrated analysis and information flow, is a powerful way to enhance civil engineering capabilities. Yet, relatively few have taken...
Managing AutoCAD and Intergraph MicroStation Systems
The reality today is that Computer Aided Design information is being transferred from one CAD system to another. More often, sharing CAD information among the design team requires multiple...
Computerized Approach for Forecasting the Rate of Cost Escalation
This paper reviews the treatment of escalation in construction costs. The causes of escalation are outlined and the effect of escalation on the contractor and the owner is discussed. Various...
Simulation of ATIS Strategies to Mitigate Special Event Congestion
This research extends the performance and application of DYNASMART, a dynamic traffic simulation model which incorporates the three elements necessary for modeling traffic flow under information:...
Quality Control and Constructability of Slabs on Grade With Expert Systems
Constructability and quality control problems associated with the construction of slabs on grade are many. They vary from problems associated with cracking, scaling, dusting and spalling,...
Framework for an Automated Quality Control System in Working Drawing Production
CAD use for the planning, design, construction and operation of buildings continues to expand at a rapid pace throughout the industry. While CAD applications include a variety of uses...
