EntrapmentMonitoring at an Arctic Seawater Intake
This paper presents the results of a monitoring program designed to quantify the level of fish entrapment during a seawater treatment plant (STP) operation as well as immediate and delayed...
Rediscovery of the Lower Duwamish River Estuary Solutions to Pollution by Point and Nonpoint Source Controls
Beginning in 1960, a series of point-source pollution controls, new sewage interceptors and treatment plant upgrades dramatically improved conventional water quality parameters in the...
Nitrification in a Salt Wedge Estuary
Autotrophic nitrifying bacterial activity and numbers were measured in a salt wedge estuary receiving ammonium-rich effluent from a municipal secondary wastewater treatment facility. Instream...
Use of Fish Liver Pathology as a Tool for Environmental Assessment (`siabstract)
Despite the recognized value of fish liver pathology as an environmental assessment tool, little guidance is available on the design and interpretation of such studies. Proper study design...
U.S. Coast Guard Experience with Wave Turbines
Since 1980 the United States Coast Guard has been developing a lighted buoy for exposed areas and congested harbor entrances. The buoy hardware is of conventional design while the signal...
An Assessment of the Soft Approach to CZM
During the early development of the national coastal zone management program there was no federal prescription with regard to how coastal states should proceed in establishing their programs...
Sewage Trapping by Water Parcels in Puget Sound
Sewage effluent entering Puget Sound, Washington, often becomes trapped in discrete parcels of water. The parcels are easily identifiable in vertical density profiles as layers of well-mixed...
Environmental Impacts from Treated Ballast Water Discharge into Port Valdez, Alaska
A ballast water treatment plant has operated on the south shore of Port Valdez, Alaska since 1977. In recent years the plant processed, on the average, nearly 51,000 m**3 of the ballast...
The Benefit of Utilizing Case Specific Modelling and Data to Determine Effluent Limitations
This abstract refers to the results of a normal conservative approach to a more realistic, substantiated approach to determining effluent limitations. The new approach was used to establish...
Application of an Ecosystem/Water Quality Model as a Tool for Managing Estuarine Water Quality
A laterally averaged two-dimensional computer model was developed to simulate the hydrodynamics, transport, and ecosystem dynamics of Budd Inlet, a small partially mixed estuary located...
Cogenerating Columbia River Salmon and Hydropower
In recent years a number of regional institutional arrangements have been consumated which have potential for reducing overfishing of Columbia River chinook stocks. In the Pacific Northwest...
Athens Siphon and Outfall
More than 130 million gallons of untreated domestic and industrial wastewater are discharged each day into the sea near Athens. To mitigate this situation, the government of Greece is...
Embankment Over Fly Ash Pond at Portsmouth Power Station
The fly ash and bottom ash sediments from the Portsmouth Power Station in Portsmouth, Virginia were being sluiced into a 39 acre diked ash pond near the plant. The plant was about to convert...
Water Treatment Plant Sludge as Landfill Liner
Chemical sludge is produced in large quantities during the water treatment processes. The present regulations pertaining to the disposal of solid wastes impose many constraints on any...
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...
Environmental Monitoring and Observations Before and During Excavation of a Landfill in Owatonna, Minnesota
A Minnesota landfill inactive since 1962 was excavated in 1985 to prepare the site for construction of a new waste water treatment plant. The excavation refuse was disposed of in nearby...
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...
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....
