Stabilization of FGC Wastes
Presently, flue gas cleaning (FGC) wastes (scrubber sludges and flyash) are produced in large quantities, with future production likely to increase as utilities install additional stack...
Guide for the Design and Use of Concrete Poles
Prepared by the Concrete Pole Task Committee of the Committee on Electrical Transmission Structures of the Structural Division of ASCE. This guide presents...
Foundations for Transmission Line Towers
This special technical publication contains the proceedings of a two session symposium on foundations for transmission line towers. These papers were written by researchers, geotechnical...
Energy Solutions Today for the Nineties
Optimal use of energy resources requires intelligent planning by all segments of society, especially the technical disciplines. Civil engineers play a key role in developing energy resources...
Golden Gate Bridge Improvements
The Golden Gate Bridge, Highway and Transportation District engineer talks about improvements made to the Golden Gate Bridge since opening day. Improvements covered include: wind bracing,...
Water Jets: Concrete Yes, Tunneling Maybe
High pressure water jets are demolishing concrete from bridge and parking decks, faster and at lower cost than by traditional means. The technique is fast becoming an acceptable option....
Computer Scheduling: On-Line and On-Time
The Intermountain Power Plant, a coal fired, 761 MW coal fired electrica generating facility, has been completed months ahead of schedule and substantially under budget. Project managers...
Implementation and Management of a High Technology Irrigation System
Eastern Oregon Farming Company (EOFC) irrigates 12,000 acres using a fully pressurized irrigation system. In 1981, the system was operated with minimal flow and pressure measurements and...
Instrumentation: Canal De Provence
A report describing the Canal de Provence and its specific hydraulic regulation system, 'dynamic regulation', is presented in another conference paper. The present...
Penetrative Convection in Mixed Layer Models
While surface heat transfer is important in lakes and reservoirs, solar radiation, which penetrates the water surface and is absorbed in the water column, also exists. In this work, a...
Air Chamber Surge Tanks in High Head Hydro Plants
The U. S. Army Corps of Engineers Alaska District considered an air chamber during the design of the 'Crater Lake phase of the Snettisham Project near Juneau, Alaska. A conventional...
Time Variability of Suspended Material Concentrations in Estuaries
The concentration of suspended materials (SMC) within estuarine systems varies in response to a variety of factors. This variability complicates sampling SMC and establishes particular...
Design and Performance of a Siphon Penstock
Siphons can be a cost effective alternative to more traditional means of conveying water to hydroelectric turbines. The City of Ann Arbor, Michigan selected a siphon as the most cost effective...
Nonhomogeneous Terms in the Unsteady Flow Equations: Modeling Aspects
A study is in progress to identify the relative significance, effects, and benefits attributable to the use of one-dimensional, unsteady, open-channel, flow-simulation models employing...
Effect of Atmospheric Forcing on Tide Propagation
This paper presents computations and observations indicating that nonlinear interaction with wind waves and subtidal sea level changes can change estuarine motion in the tidal frequency...
Nontidal Exchange Processes at the Chesapeake Bay Entrance
Magnitudes of gravitational and meteorologically-driven exchange at the entrance to the Chesapeake Bay are compared using current measurements, numerical model runs and subtidal volume...
The Development of Test Cases for Hydrodynamic and Transport Models
This paper reviews the test cases employed by several investigators in the development of two- and three-dimensional finite difference and finite element hydrodynamic and transport models....
Modeling the Effect of Weirs on Reservoir Releases
A computer model was developed to examine the influence of weirs on the rise of water levels and increases in velocities from reservoir releases. The model allows for investigation of...
Hydraulic Model to Improve Debris-Handling Capability of Waterford Unit 3 Intake Canal
A 1:30 scale model was used to test the effectiveness of various modifications to the Waterford Unit No. 3 intake canal. The objective of the study was to assist in the development of...
Low Head Hydropower Finite Element Analysis
Finite element analysis provides a means of predicting the flow conditions resulting from the operation of a proposed hydropower facility. The results of a finite element flow analysis...
