High Speed Ground Transportation: Some Historical Perspectives
The definition of `high speed' ground transportation is relative to the transportation technology of a period. Thus it might be argued that high speed ground transportation began early...

High Speed Rail vs. Maglev in the Quebec City-Windsor Corridor: A Comparison of Energy Impacts and Emissions
This paper reports energy impacts and emissions for two high speed ground transportation systems that are considered for implementation in the Quebec City-Windsor Corridor (Canada). In...

Aerodynamic Resistance of Trains Running Through a Tunnel
In what follows, some previously published results and formulae have been combined in order to obtain an applicable tool for evaluating the energy consumption of trains in tunnel as a...

Coastal Non-Point Source Pollution Abatement: The Shipbuilding and Repair Industry
In cooperation with several shipbuilding and repair businesses and several state environmental regulatory agencies, site visits, waste-minimization assessments, and storm water sampling...

Breakwater Design in the Chesapeake Bay: Dealing with the End Effects
This paper documents various methods for treating the terminal ends of headland breakwater systems. Twelve sites in Chesapeake Bay were selected for study. In selecting design alternatives,...

Waves and Currents Near the Kinburn Spit Extremity
A method of calculation of wave transformation and of currents generated by waves in a surf zone, including a spit extremity is offered. No additional hypothesis on radial stress and wave...

Estimating ET Using Turbulent Coherent Structures
Two methods for estimating sensible heat flux to use in energy balance equations for computing crop evapotranspiration are discussed. The methods use high frequency temperature measurements...

Hourly Reference Evapotranspiration by Bowen Ratio and Penman Methods
Hourly and daily reference evapotranspiration (ETo) computed from Bowen ratio energy balance (BREB) measurements were compared with ETo estimated from the hourly Penman equation (ETP)....

Compacted Spillway
The compacted spillway (CSW) refers to a spillway accompanied by jets located on its face to dissipate the excess energy. The (CSW) has a standard ogee profile with three jets located...

Observations of Artificial Destratification
Artificial destratification using bubble plumes is one means whereby low dissolved oxygen in the hypolimnion of lakes and reservoirs may be averted. Temperature and DO were measured at...

Hydrodynamic and Toxic Contaminant Dispersion in the Lower St. Marys River
A numerical model that simulates the hydrodynamics and the transport of toxic contaminants in the Lower St.Marys River is being calibrated and verified using field data from the U.S. Army...

Development of Enhanced Tools for the Integrated Analysis of Reservoir and Power System Operations
The Tennessee Valley Authority (TVA) and the Electric Power Research Institute (EPRI) have initiated a collaborative project - the INTEGRAL Project - to develop improved tools for coordinating...

Hydraulic Modeling of High Unit Discharge Energy Dissipators
The incorporation of an efficient and economical energy dissipation device is critical with respect to the safe operation of a high unit discharge spillway. The development and design...

Integration of Environmental Management with Reservoir and Power System Operations
Two examples related to the Tennessee Valley Authority's reservoir and power systems operation with environmental performance and management as major goals are given in this paper. One...

Design of a Curved Baffle Energy Dissipation Structure
A curved baffle energy dissipation structure was designed and constructed based on the results of hydraulic and analytical models. Field tests of the prototype demonstrate close comparison...

Hydrologic Design: Extending Traditional Methods
A review of traditional hydrologic design shows that it is inadequate. The continued adaptation of manual techniques into computer software without a major change in fundamental assumptions...

Potential of Vegetable Oil as a Transportation Fuel
The esters of vegetable oils (Biodiesel) have potential as direct replacements for diesel fuel in compression ignition engines. This paper discusses fuel properties, short and long term...
