Volatilization of Cesium and Ruthenium From High-Level Waste Glass
The contamination of the air above high-level waste glass by ¹³⁴Cs, ¹³⁷Cs and ¹⁰⁶Ru...

Calibration of High Frequency Pollen Sequences and Tree-Ring Records
Two radiocarbon dated paleoenvironmental records from southern Nevada are being examined with the possibility of correlating high-frequency pollen samples with nearby long-term tree-ring...

Ventilation and Construction Considerations for a High Level Nuclear Waste Repository
The storage of high level nuclear waste in an underground repository presents engineering problems in ventilation, construction methods and plan, and in proposed retrievability. Temperatures...

Development of a CRUD Particle Size Distribution and Its Effect on Cask Source Term and Containment Analyses
Spent pressurized-water reactor (PWR) and boiling-water reactor (BWR) fuel rods from three reactors were examined by hot cell periscope, energy dispersive x-ray analysis, and scanning...

Prefabrication of Ceramic Segments by Compaction and Microwave Fusion Technology
Material source and environmental impacts are two major concerns in the application of conventional concrete technology in lunar base construction. In this study, the simulated lunar soil...

Investigation of HVAC Systems in Low Gravity Application
This paper has been developed to identify and summarize the principal areas of investigation necessary to design and install functional HVAC systems in low gravity applications. These...

The Optimum Dimensions of Radiative Spines
Radiative pin fins (spines) are important in conjunction with heat rejection systems for space applications. In the design of radiators for space applications, spines possessing minimum...

Upgrading Hydraulic Infrastructure for Level One Redundancy
In the current paper a methodology is presented for upgrading any single source water distribution system in order to provide a level one system redundancy at a minimum cost. A level one...

Predicting Watermain Breakage Rates
Recent studies on water main breakage have shown significant spatial and temporal clustering in the breakage pattern. The methodology described in the paper provides the basis for a prediction...

Evaluation of Global Warming Impact on Soil Moisture and Water Runoff in Texas
In this paper a numerical evaluation of the variability of soil moisture and surface runoff due to global warming is carried out. An analytical model of the soil moisture balance based...

A 3D-Stereo Graphics Interface for Operational Great Lakes Forecasts
A system for real-time predictions of Great Lakes physics and transport characteristics is now being implemented. The full 3D nature of the predictions demands accurate, high speed computer...

Siting the New Boston Harbor Outfall: Near-Field Analysis
In the near-field analysis for Boston's proposed Deer Island outfall to Massachusetts Bay, multiple initial dilution calculations were applied to estimate the frequency distribution...

A Method for Estimating Peak Flows from Small Agricultural Watersheds
An attempt was made to develop a method for estimating peak runoff from agricultural watersheds by analyzing precipitation and runoff data, and incorporating the results into a procedure...

Water Erosion Prediction Project (WEPP) Watershed Model: Hydrologic and Erosion Calculations
The Water Erosion Prediction Project (WEPP) watershed model is a distributed continuous simulation model developed to compute the spatial and temporal distribution of erosion and deposition...

Morphology and Roughness in the Hydraulics of Large Bed Element Channels
The evolution of natural steep channels is a function of two factors in accordance with the principle of least action: flow distribution in the channel and terrain geomorphology. Large...

Precipitation Variability Effects on Modeled Soil Water Deficits
Effective management of forages in steep Appalachian pastures requires an understanding of hydrologic and microclimatic processes on the area. This study was conducted to determine the...

Flume Experiments on Debris Flow
With the different characteristics of grain motion in debris flow, three layers are vertically divided, i.e., viscous collision layer, inertial collision layer and suspension layer. Both...

Evaporation and Snowmelt Estimates from Satellite Data
Satellite imagery has been used to estimate saltwater evaporation and snowmelt runoff. Water surface temperatures can be obtained from satellite thermal infrared data. Saltwater evaporation...

Large Floods and Climate Change in the Southwestern United States
Floods can have a tremendous impact on water resources but their properties may fluctuate at frequencies that defy recognition in short-term instrumented records. Paleoflood deposits provide...

Waves in a Fluid Mud Layer Flowing Down an Incline
To model the dynamics of fluid mud, lava, or debris with a high concentration of cohesive clay particles, we consider a thin sheet of Bingham plastic fluid flowing down a slope. The Bingham...
