Beneficial Use Alternatives for Water Treatment Plant Residuals
The beneficial use alternatives which are currently in practice for water treatment plant residuals and their relative advantages and disadvantages are summarized in this paper. The alternatives...

Beneficial Use of Ash: An Innovative Approach to Sludge Management
Disposal of ash resulting from the incineration of municipal sewage sludge has historically been a relatively easy, albeit, expensive requirement. The traditional method of disposal is...

DBP and Hardness Control by Membrane Filtration
Ultra (UF) and nanofiltration (NF) were evaluated for removal of disinfection by-product (DBP) precursors and hardness from Rio Grande water in New Mexico and Texas. In order to compare...

Treatment of Drinking Water Containing Bromate and Bromide Ions
Granular activated carbon and reverse osmosis nanofiltration and hyperfiltration were examined for both bromate and bromide ion removal using surface treated water in New Jersey. Bromate...

Innovative Instrumentation for a Physical Model of River Ice Transport
Large physical models often require the use of innovative instrumentation and measurement techniques. Hydraulic models that attempt to simulate the effects of stationary ice covers put...

Effects of Flow Duration on Local Scour at Bridge Piers in New York
The relation of local scour to the duration of high flows and other hydraulic properties is being studied at 31 bridge sites in New York State. Clear-water scour is common at most of the...

A Coupled GIS-Water Quality Modeling System
A modeling framework is developed which uses a geographic information system (GIS) to perform many of the time-consuming tasks needed to set up and run a general water quality model. The...

Hydro Plant Research Data Acquisition System
The Colton Hydroelectric Development, located on the Raquette River in the northwestern part of New York State, is the site of a two year research project to test the use of heated trashracks...

Stratified Flow in an Impounded Inland River
Stratified flow in the Seneca River of central New York is described. This flow condition occurs in the vicinity of the outflow from saline Onondaga Lake, and exists both upstream and...

Verification of a Three-Dimensional Model of Delaware Bay
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...

Design of Manning's-Rougness-Coefficient Study in New York State
Field-collected hydraulic data can be used to compute roughness coefficients for channels with different hydraulic characteristics. Suggested criteria for the design of a roughness-coefficient...

Study of Friction Factors in the Upper Reaches of the Rio Grande
The purpose of this study is to investigate the determination of Manning's roughness in the upper Rio Grande river basin and compare results to other studies where Darcy Weisbach friction...

Roughness Coefficients for High-Gradient Channels in New York State
Manning's roughness coefficients (n values) were computed for a range of flows at six streams in New York State (USA) that have high energy gradients (greater than 0.002) and large median...

Streamflow Related to Channel Geometry in Northern New England
Channel geometry measurements can be used to estimate various streamflow characteristics at ungaged stream locations. Channel cross section dimensions and sediment size distributions were...

Sediment Modeling in the Rio Grande Conveyance Channel
The Rio Grande Conveyance Channel and the Rio Grande Floodway convey water from the San Acacia diversion dam to Elephant Butte Reservoir. The Conveyance Channel was built in early 1950's...

Development of Long-Term Three-Dimensional Hydrodynamics in Long Island Sound for Use in Water Quality Modeling
The Blumberg-Mellor (1987) three-dimensional hydrodynamic model has been adapted by the National Oceanic and Atmospheric Administration's National Ocean Service (NOS) to provide hydrodynamic...

Investments in the Future
The projects that earned the 1994 Outstanding Civil Engineering Achievement Awards of Merit were improvements to the nations transportation and environmental infrastructures. On the outskirts...

Computer-Integrated Construction
Computers have been used quite successfully as replacements for manual drafting, but to stop there seriously underuses the potential of computer aided design. By using the computer's...

The Key is Constructability
Construction generally involves the collective efforts of owners, designers, contractors and suppliers. During the design phase, the engineer should be mindful of such critical elements...
