Design of Large Capacity Coal Silos for Service Life
Design and construction of Large Capacity Coal Silos for service life requires a careful consideration of the silo configuration as well as the material handling system. This paper presents...

Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...

Sustainable Energy Systems: A New Paradigm for New Energy Technologies
The fundamental links between energy production/use and the environment are becoming increasingly apparent. The major environmental challenges of global climate change, acid precipitation,...

A Graphical Database for Transportation Systems
A graphical database composed of programmable objects analogous to elements of a physical plant of a transportation network is presented. The discussion reviews the application of a graphical...

Watershed Planning in Western Pennsylvania—A Case Study
This paper presents and describes the watershed planning activities being pursued in Allegheny County, Pennsylvania. The regulatory, institutional, and technical framework of the planning...

Hermite-Galerkin Model for Dam-Break Floods
A model based on the finite element method using cubic Hermite basis functions and Galerkin weighting was formulated to solve the partial differential equations that govern unsteady one-dimensional...

Model Identification of an Arch Bridge for Dynamic Analysis
The dynamic responses of a steel deck tension-tied arch bridge subjected to earthquake excitations were investigated. The 189 m (620 ft) Birmingham Bridge located in Pittsburgh, PA was...

Municipal Stormwater Management Ordinance Development and Implementation in Pennsylvania
This paper discusses the critical planning and engineering components of a sound stormwater management ordinance and how they can be shaped to avoid commonly encountered basin-wide implementation...

Rebuilding Philadelphia's El
In reconstructing an urban transit system, the challenge in Philadelphia was to do it without disrupting peak hour commuter traffic or disturbing activities on the street and sidewalks...

Some Dilatometer Test Results in Pennsylvania and New York
This paper starts with a brief introduction to the dilatometer and piezoblade. Test results in four different areas are presented. DMT soundings at LR 67057 (Legislative Route numbers...

Development, Calibration and Application of Runoff Forecasting Models for the Allegheny River Basin
The computer program HEC1F, developed by the Corps of Engineers' Hydrologic Engineering Center, performs runoff forecasting. The focus of this paper is on application of HEC1F...

The Drought of 1988 in the U.S. Army Engineer District, Pittsburgh
The summer of 1988 was the hottest of the century in the Pittsburgh District. Pittsburgh experienced 38 days of 90 F degrees or more, including 3 days above the 100 F degree mark. This...

Models vs. Methods in Urban Drainage Calculation
This paper summarizes the findings of a recent study at Penn State aimed at recommended hydrologic techniques for small developing watersheds. The specific desk-top methods investigated...

Harnessing the Allegheny: Four Low-Head Projects
The navigable portion of the river, extending northeast of Pittsburgh approximately sixty miles, contains eight lock and dam systems under the jurisdiction of the U.S. Army Corps of Engineers...

Simulation of Precipitation by Weather-Type Analysis
A new approach that uses weather-type analysis as a basis for stochastic precipitation modeling was developed and tested for Philadelphia, Pennsylvania. The weather types permit the identification...

Classic Wood Structures
Wood has been used in a wide range of structural applications. When properly maintained, these structures can have a useful life from 50 years to several centuries. Thirty-seven unusual...

Movable Dam—Gate Selection Procedure
Very few new dams are now being considered, particularly for waterpower and even more specifically for low head waterpower in the lower reaches of major rivers. The City of Harrisburg,...

New Martinsville Hydroelectric Project
The 34MW New Martinsville Hydroelectric Project is presently under construction in West Virginia. Located at Hannibal Locks and Dam near river mile 126 downstream from Pittsburgh, PA,...

Low Head Hydraulic Model Justifies Cost
In many cases, developers of low head hydroelectric plants fail to use physical hydraulic modelling as a tool in the design process. Economic constraints are often cited as the primary...
