Modeling Emissions from Aerobic Treatment Systems
A mathematical model has been developed specifically for accurately quantifying the dispersion of emissions in the near vicinity of a groundlevel area source. This model accounts for variations...
Assessment of Effects of a Water Supply Withdrawal on Downstream Flows for Anadromous Fish Reproduction
A BASIC computer model was developed to simulate reservoir operations in conjunction with a proposed water supply withdrawal. The model was used to assess the potential impacts of the...
Using Multiple Water Quality Models for Determining Variable Emission Levels for Wasteload Allocation
We present a methodology for determining the least-cost wasteload allocations from multiple point sources discharging into a single water body. The system of point sources is modeled as...
An Analysis of Modeling Techniques in Pollution Management of Natural Water Systems
This paper will focus on various models to demonstrate the difficulties with modeling techniques. The difficulty with developing a valid model for a system is explored through the study...
Information Entropy and Environmental Engineering
Environmental engineering decisions are often made with limited information. In such cases it is useful to express uncertain quantities with a probability distribution. The use of information...

Breaking Down the Barriers
The structural engineering of multistory buildings is a complex and time-consuming chore, but new design and analysis tools can greatly simplify the task. The article traces the development...
LRFD: Still Waiting
Introduced in 1986, load and resistance factor design (LRFD), has a way to go before it becomes standard practice for steel design. LRFD-based design typically results in savings on gravity...
CADD for Export
By using sophisticated structural design software and high-speed PCs, engineers in Pittsburgh overcame myriad problems when designing a highrise industrial tower in India. First, they...
Monte Carlo Simulation Techniques for Predicting Annual Power Production
The problem of the creation of a simulation model utilizing the Monte Carlo method at a single site is addressed. The result of the analysis is a picture of the production at the site...
Techniques for Balancing Instream Flow Needs with Project Operation
Balancing power and non-power benefits of hydroelectric developments has become a controversial issue in the relicensing of projects. Multiple project and multiple objective flow management...
Harrisburg Hydroelectric Project?Water Quality Issues
The Harrisburg Hydroelectric Project is a proposed 34.4 MW hydroelectric facility on the Susquehanna River near Harrisburg, Pennsylvania. The project will consist of a 16.5 ft high gated...
Using Project Management Techniques in Hydro-Relicensing
To answer a pressing need for managing today's complex process and requirements of hydro relicensing, Central Maine Power Company (CMP) has applied the principles of project management,...
EPRI's Pumped Storage Planning and Evaluation Guide
EPRI's Pumped Storage Planning and Evaluation Guide was published in 1990. The Guide provides step-by-step procedures to: (a) evaluate pumped-storage operation in a utility...
Hydraulic Model Studies for Non-Federal Projects at Federal Dams?A Case Study
This paper will discuss the hydraulic model studies for hydropower projects developed by Arkansas Electric Cooperative Corporation (a non-federal entity) at existing Corps of Engineers...
Overcoming the Obstacles?Hydroelectric Development on the Kankakee River
A number of difficulties were encountered and resolved during development of a 1,200 kW hydroelectric project in northeastern Illinois. Located at the site of an abandoned hydroelectric...
Undeveloped Hydropower Resource Potential
The public hearings conducted as part of the National Energy Strategy produced testimony that concluded that the potential for development of hydropower was not well defined. As a result,...
Technology Transfer for Small Hydro
The wide range of different definitions of what constitutes a small hydroelectric power plants is discussed and the conclusion is drawn that this definition should be based more on the...
Load/Resource Matching for Period-of-Record Computer Simulation
The Southwestern Power Administration (Southwestern), an agency of the Department of Energy, is responsible for marketing the power and energy produced at Federal hydroelectric power projects...
Computer Modeling of Reservoir Sedimentation and Sluicing
A recently developed computer program which simulates the evolution, growth, and movement of a submerged delta in reservoirs was tested for Spencer Dam and Reservoir in Nebraska. The code,...
