Energy Recovery
In Albany, N.Y. the state and city cooperated in designing and building a refuse-into-steam energy plant that has several unique features. In most such facilities, the entire plant is...

Techniques for Automating the Process of As-Built Reconciliation
The approach utilizes an electronic digital 'ruler' capable of measuring distances to 100 feet with a resolution of 1/100 of a foot. This ruler interfaces to...

Safety Investigations of Existing Spent Fuel Storage Structures for Increased Spent Fuel Storage Capacity
Delays in the solution of disposal problems continue to create the need for additional on-site spent fuel storage capacity at commercial nuclear power generating facilities. Rod consolidation...

A Flat-Dilatometer Study of Lateral Soil Response
The effect of flat dilatometer penetration on the lateral stress conditions in soil around the dilatometer blade and the soil response against dilatometer diaphragm deflection were investigated...

Database Management
Computer aided design systems have found widespread acceptance from Engineering companies as drafting/detailing/drawing tools. While this has brought a dramatic productivity improvement...

Wetlands Development in Moderate Wave-Energy Climates
For the last three years springs of Spartina alterniflora have been planted on portions of Theodore Island, a dredged material island in Mobile Bay, Alabama. The purpose of the planting...

Dredging for a new Port - Puerto Bolivar, Colombia
A major coal export terminal at Bahia Portete, Colombia, is being developed as part of the Cerrejon Coal Project - North Zone, where one of the world's largest coal mines...

Acoustic Silt Density Measurement
Significant savings can be achieved on the costs of operations for the deepening and maintenance of navigation channels and harbor basins in muddy areas provided that computations are...

Influence of Roughness on Velocity and Dispersion at Low Flow
Dependence of the hydraulic and transport characteristics of low flow on channel roughness is investigated. Empirical expressions are used to estimate roughness coefficient as a function...

Flow Parameters of Fluid Mud
A set of small-scale, high-resolution velocity and stress sensors based on rugged metal-clad hot wires and epoxy-encapsulated hot films is to be evaluated for its performance characteristics...

Movement of Tractive Sediment from Disturbed Lands
The Smoky Creek basin of the coal area of northeastern Tennessee shows extensive evidence of tractive movement of coarse sediment from mined tributary basins into the main channel. Coal-rich...

Modeling Effects of Toxicants on Aquatic Systems
Potential effects of chemicals on biomass production in aquatic systems are extrapolated from laboratory toxicological assays. The extrapolation requires that the effect of acute toxicity...

Vacuum Assisted Pipelines Operation
In the process of upgrading the sewerage facilities for Lancaster, Pennsylvania, it was decided to combine two existing facilities into one new facility. This required the design of three...

Hydrotest Rupture of Penstuck Liner at Bath County
Bath County is the construction site of Virginia Electric and Power Company's pumped storage project. Rupture of a penstock liner during hydrotest at high pressure threatened...

A Three Dimensional Hydraulic Jump
A study is conducted to define the three-dimensional hydraulic jump that occurs in a rectangular channel downstream of a rectangular contracted sluice gate. A sequent depth ratio equation...

Streamflow Measurement and Analysis for Northwest Rangelands
Watershed hydrologic and sedimentation investigations on the Reynolds Creek Experimental Watershed in southwest Idaho were initiated in 1960. Major objectives of the watershed research...

Small Hydropower Development for Mining Industry
In deep mines, large refrigeration systems are employed to condition the working air to help control temperature and humidity. Large quantities of water are required to be brought into...

Field Flow Measurement of Hydro-Turbine Efficiency
Performance tests were conducted at Great Northern Paper (GNP) Company's Weldon Hydroelectric Station. The purpose of the tests was to calibrate the Winter-Kennedy taps and...

Hydro-Thermal Power Plants with Pumped Storage
The concept of pumped storage can be justified through the development of hydro-thermal power plants. The hydraulic equipment for power plants of this kind is available in the market meeting...

Integrated Small Hydro Energy Development
Small hydro power development integrated with other renewable energy sources is economical. Civil engineering components if suitably selected and designed reduce power development costs...
