Development of Optimum Beach Fill Design Cross-Section
Accurate beach profile surveys, wave information, and sediment data taken at Ocean City, Maryland provided an opportunity to evaluate four beach fill design alternatives using the beach...

Calculation of Three-Dimensional Turbulent Flow in Francis Turbine Runner
A numerical scheme, based on MacCormack's predictor-corrector explicit finite volume method, for solving three-dimensional weakly compressible inviscid, laminar, and turbulent...

Pressure-Time Flow Measurements Under Adverse Conditions
Theoretical analyses suggest that the pressure-time method is capable of accurately determining flow rate in the short, varying cross section, 'semi-scroll' penstocks...

Uncertainty in Climate Change and Drought
A series of projections of climate change were applied to a watershed model of the Delaware River basin to identify sources of uncertainty in predicting effects of climate change on drought...

Potential Effects of Global Climate Change on the Central and Southern Florida Project
The possible impacts of some potential climate change effects such as sea level rise, changes in tropical cyclone intensity and frequency, and changes in precipitation and temperature...

Taller Tunnels
Between 1984 and 1991, Shannon & Wilson, Inc., Seattle, designed renovation programs for more than 25 mi of tunnels for four western railroads. We performed all of this work under...

Anatomy of Asphalt
Two main factors will combine over the next several years to alter the composition of asphalt pavements, which make up more than 90% of the paved roads in the U.S. First, a major research...

Measuring Section-Related Traffic Data by Correlation Methods—A New Approach to Traffic Monitoring and Control
Traffic monitoring and control systems require reliable realtime data on traffic flow for an efficient performance. A new 'class' of data, the so-called section-related data such as journey...

Heavy Traffic Control Measurement Techniques and Control Strategies
Advanced technologies for traffic detection for freeway control systems are described. mm-wave radar detectors are used with a correlation of vehicle reflexion patterns to acquire section...

The Global Classroom Project

The Long-Term Climate Change Assessment Task of the Protective Barrier Development Program for Low-Level Waste Site Remediation at the Hanford Site
A study plan is being developed to guide a multiyear program to assess long-term climate change and optimize the design of protective barriers. A protective barrier alternative is being...

Environments of the Last 50,000 Years in the Vicinity of Yucca Mountain, Central-Southern Nevada
Located within the southern hydrographic Great Basin, the Nevada Test Site lies astride the transition between the Mojave Desert to the south and the Great Basin Desert to the north. Fossil...

Modeling Future Climates for Nuclear Waste Disposal
In order to ensure safe long term storage of nuclear waste it is necessary to consider possible consequences of future climate change. A program of long term climate scenario development...

Space-Based Control of the Climate
The expected global greenhouse warming of 2 °C may be reversed by a space-based screen that intercepts 3% of the incident solar radiation. Space-based devices may also mitigate the ozone/UV...

Some Hydrological Impacts of Climate Change for the Delaware River Basin
To gain insight into possible impacts of climate change on water availability in the Delaware River, two models are linked. The first model is a monthly water balance model that converts...

Predicting Effects of Global Climate Change on Reservoir Water Quality and Fish Habitat
This paper demonstrates the use of general circulation models (GCMs) for assessing global climate change effects on reservoir water quality and illustrates that general conclusions about...

Data Collection Using a Portable Computer and Digitizing Tablet
This paper describes a data collection system developed by the New Hampshire Technology Transfer Center. The key features of this data collection method are its ease of use, single step...

DELVACS: A Computer Program for Performance Evaluation of Low Volume Coordinated Semi-Actuated Systems
This paper presents a computer program which provides a tool for making choices between coordinated and free operation on an arterial roadway under semi-actuated control. The decision...

Synthetic O-D Microcomputer Trip Table Packages
Three microcomputer models for synthetic estimation of origin-destination trip tables are compared based on theoretical foundations, implementability, and operating performances. Each...

Climate Change and Resulting Hydrologic Response: Illinois River Basin
In the last 20 years, the northern half of the Illinois River basin has been experiencing a wetter and cooler climate. This climate change has significantly increased Illinois River flows...
