Development of Optimum Beach Fill Design Cross-Section
Accurate beach profile surveys, wave information, and sediment data taken at Ocean City, Maryland provided an opportunity to evaluate four beach fill design alternatives using the beach...
PITTLEACH: A Numerical Model of Landfill Stabilization
This paper addresses the theoretical development, use and application of PITTLEACH, a computer program conceived to simulate the processes of landfill stabilization. Since the physical,...
Propositions for Packed Bed Adsorption Reactor Design
This paper states ten propositions which describe the behavior of 'wave fronts', i.e., adsorbate concentration versus distance profiles at given elapsed times,...
Who is Taking Out the Garbage?
Due to the shortage of landfill space and the increasing amount of waste being generated, current waste disposal techniques should be studied and revised. New methods should be implemented...
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...
A New Graphic Technique for Reporting Soil Quality Analyses
Boston's Artery/Harbor Tunnel Project is currently the United States' largest highway construction project. One of its major issues is the disposal of an estimated...

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...
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...
Evaluating Hydro Relicensing Alternatives?Impacts on Power and Non-Power Values
The relicensing of 300 hydroelectric plants in the next decade involves a total capacity of about 4,000 MW - a $10 billion value. A methodology recently developed by Decision Focus Incorporated...
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...
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,...
Document Image Systems for Hydro License Compliance
This paper will present one company's experience in selecting and implementing a document imaging system for management of correspondence, environmental studies, dam safety...
Calculation of Three-Dimensional Turbulent Flow in Francis Turbine Runner
A numerical scheme, based on MacCormack's predictor-corrector explicit finite volume method, for solving three-dimensional weakly compressible inviscid, laminar, and turbulent...
Design of Powerhouse Spiral Case Considering Three-Dimensional Action
A commonly used approach of designing semi-spiral cases for Kaplan turbine installation using two-dimensional frames becomes unsuitable for large diameter turbines and/or high heads. The...
Stability Analysis of Gravity Dam Foundations with Horizontal Seams
Determination of the overall factor of safety against sliding is an important aspect in concrete dam design. Limit equilibrium methods have serious limitations. A method for determining...
Seismic Analysis of the Bonneville 1st Powerhouse
The Bonneville 1st powerhouse monoliths were constructed during the period of 1938 to 1942 and were designed against seismic loads using the old lateral coefficient method. The Corps of...
Effects of Uplift on a Gravity Arch Dam
This paper evaluates the behavior of a gravity arch dam when subjected to normal static loads and internal hydrostatic pressure (uplift). The ability to model uplift has become necessary...
Superplasticized Concrete for a Prefabricated Powerplant Structure
This paper describes the use of superplasticized concrete in extremely difficult placements inside a restricted access preassembled powerplant structure (PPS) of a 192 MW Sidney A Murray...
