Honolulu Harbor Ship Traffic Simulation and Animation Study
A computer simulation and animation study was conducted to investigate the operational impacts of projected ship traffic increases and harbor reconfiguration specified in the Honolulu...
Estimating Urban and Suburban Sewage Flows with Assistance of GIS Technology
The Massachusetts Water Resource Authority (MWRA), an agency created by the Massachusetts legislature to provide wholesale water and sewer services to the metropolitan Boston areea, is...
Development of the San Fernando Basin Groundwater Flow Model
This paper describes the development and calibration of the San Fernando Basin (SFB) groundwater flow model. The SFB is the largest groundwater basin in the Upper Los Angeles River Area...
Optimization Model for Operation of Recharge Basins
A mathematical model is developed for the optimal operation of recharge basins, which is a non-linear optimization problem. The objective of the model is to determine the operation that...
Habitat Simulation in United States, Britain, and France
The need to identify an instream flow requirement for water resources management exists in a number of countries. The use of habitat simulation in the United States, Great Britain, and...
Are High and Low Flow Habitat Values Really the Same?
The Instream Flow Incremental Methodology calculates physical habitat as a weighted sum. Suitability of use information for each modeled species and life stage are used to weight each...
Three Dimensional Modeling of Watershed Hydrology
A three dimensional finite element numerical model is developed for the first order watershed hydrology using 8-noded isoparametric brick elements. The 3-D subsurface flow in a hillslope...
Indicator Variography for Spatial Characterization of Aquifer Heterogeneities
The qualitative information or soft data from lithologic descriptions is processed using a state-of-the-art geostatistical approach to delineate, with quantified uncertainty, the extent...
Development of Storage Demand Relation for Reservoirs?A Probabilistic Approach
This paper presents a practical method for developing storage-demand relation for reservoirs by a probability analysis of the stream flow data. The method was employed by the author for...

Properties of Composites Using Recycled Plastics
Recycled poly(ethylene terephthalate), PET, mainly recovered from used plastic beverage bottles, can be used to produce unsaturated polyester resins. Polymer concrete (PC) and polymer...
From Sludge to Brokered Biosolids
At the end of June, a sludge filled barge pulled away from New York harbor for the last time. It traveled more than 100 mi offshore, where workers unloaded some of the 355 dry tons of...
Electrokinetic Cleanups
Electrokinetic remediation of contaminated soils is a relatively new research area. Electrokinetic phenomena can be used to create barriers, and move particles, including pollutants such...
Landfill-Cover Conflict
Last July, EPA's Office of Research and Development (ORD), in Cincinnati held a geosynthetic clay liner (GCL) workshop to discuss the latest technology and regulations for...
Ice Jam Configuration: Second Generation Model
An early model of ice jam configuration in wide, prismatic channels is generalized for applications to natural streams. Test runs are carried out to illustrate model performance and study...
A Conceptual Model for Vertical Frazil Distribution in Turbulent Flows
A conceptual model is presented for the evolution of frazil over depth in a turbulent flow. The net upward migration due to buoyancy of the frazil is opposed by intermittent mixing induced...
Heat Exchange at the Ice/Water Interface on Flowing Water
Any time the water flowing under an ice cover has a temperature above freezing, there is an exchange of heat between the water and the ice. Earlier work by Ashton and others provided adequate...
Multiphase Flows and the Modeling of Drifting Snow
Three categories of multiphase flow theories are commonly specialized for modeling drifting snow; the 'two-fluid' model, particle tracking schemes and kinetic...
Spray and Ice Measurement Instrumentation for Ships
Bow slamming is the primary water delivery mechanism for ship superstructure icing. Spray flux is largely dependent upon hull dynamics, and cannot be computed numerically with current...
