Anaerobic Biodegradation of High Energetics in Digestion Sewage Sludge
The digested sewage sludge culture is highly effective for denitrification and the subsequent degradation of energetics contained nitrites. Two energetics, ADN (ammonium dinitramide) and...

Results of Field Evaluations of the New Modular Inclined Fish Diversion Screen
The Electric Power Research Institute (EPRI) has developed and biologically evaluated a new type of fish diversion screen known as the Modular Inclined Screen (MIS). The MIS is designed...

Watershed Management for a Limited Coastal Aquifer System
Developing a watershed strategy, which incorporates key issues of a particular watershed, may entail the coordination of several different agencies. Work performed by the USGS, local public...

Coastal Engineering Laboratory and Field Measurements: Some Uncertainties in Measurement
In this paper two examples of uncertainties which can occur in field measurements and measurements in coastal engineering models are examined. These examples are chosen to demonstrate...

Vapor Phase Biofiltration for Removal of VOCs
The selection of an appropriate packing material for the biofiltration process is an important factor in the removal of contaminants from vapor phase. This study evaluates two different...

Environmental Planning for Water Resources Development, Cuatro Cienegas Region, Coahuila, Mexico
In 1983, biological experts met at the 16th Conference on Desert Fishes at the University of Arizona. They concluded that the Cuatro Ci?negas region of Coahuila, Mexico was one of the...

Health Risk Sensitivity to Variable and Uncertain Parameters
A methodology is presented that attempts to quantify the effects of individual variability and parameter uncertainty in a groundwater-driven health risk assessment. Two modeling approaches...

Recover Inorganic Solids from Obsolete Propellants
A feasible process was developed to recover inorganic solids (energetics and metallic fuel) from obsolete polyurethane-based propellants in order to solve their associated long-term disposal...

Mixing Influences on Cement-Based Waste Forms
High-shear, medium-shear, and low-shear mixing tests were conducted on paste and paste + fly-ash mixes: The specimens, cured for 28-days, were tested for free water generation, compressive...

Simulation of Perilithic Algae as a Biofilm and Its Interaction with the Water Column
A one-dimensional bioflim model has been constructed consisting of a particulate phase of algae and inert material and diffusive transport of nutrients and oxygen. Also included is mass...

Impacts of Sea Level Rise on Coastal Water Resources Management
Two major topics related to water resources management in coastal areas due to the impact of sea level rise are drainage problems/flood control and change of estuarine processes. Issues...

Biodegradation of Dichloromethane in Leachate
The biodegradation of dichioromethane (DCM) in landfill leachate is examined by means of a series of laboratory tests conducted in a controlled environment. These tests demonstrate that...

Combined Flood Hazard Mitigation Techniques for Comprehensive Planning? The Saugus River Coastal Flood Risk Reduction Plan
The development of an alternative Coastal Flood Risic Reduction Plan for the Saugus River was initiated by the Executive Office of Environinental Affairs (EOEA) of Massachusetts in April...

Mitigation of Flood Hazard on Alluvial Fans
A number of investigators have suggested that the limits of the traditional, stochastic, one-dimensional model of alluvial fan flooding have been reached and that there are one- and two-dimensional...

Identification of a General Linear Model for Reservoir Inflows Forecasting
General linear stochastic models represent a valuable alternative to conceptual models in order to describe runoff generating mechanisms in a drainage basin. In regions such as Quebec,...

Small Inocula Can Effect In Situ Biodegradation
This is the first report of colonization of soil by small numbers of a genetically engineered microorganism. The study suggests that the addition of small inocula of D5 to contaminated...

Biodegradation Modeling of a Closed Landfill Site
The two-dimensional model, BIOPLUME II, was applied to the closed Becker County Landfill at Detroit township, Minnesota, to study the transport of hydrocarbons occurring at the site. The...

Ecological and Biological Considerations in River Restoration
When planning river restoration projects, proper consideration must be given to the target resources of concern. This should include provisions to meet the physical, hydraulic, and biological...

Construction of Performance Contours on the Storage-Yield Plane of a Within-Year Reservoir System
The reservoir storage-reliability-yield (S-R-Y) relationships developed in the past have considered only the probability of failure to meet the target requirements, but not the likely...

Risk Analysis of Joint Reservoir Operation in Central Taiwan
Risk analysis for shortage of water on the joint operation of Li-Yu-Tan Reservoir and Shih-Kang Dam (Reservoir) in central Taiwan is presented in this paper. Deter ministic simulation,...
