Periodic Variation in Karst Stream Losses
A cave taking water from an ephemeral stream periodically reroutes surface and subsurface drainage because of a plug that forms 10 m below the main entrance to the cave. The plug of sand,...

Infiltration Properties at Two Sites in the Konza Prairie
The spatial variability of soil hydraulic properties that govern infiltration were investigated at a pristine site and an agricultural site in the Konza Prairie Research Area of east-central...

On Conductivity of Soils with Preferential Flow Paths
Laboratory soil column experiments were conducted to study the distribution of preferential flow paths resulting from removal of colloidal size clay particles. These experiments specifically...

Optimization and Simulation in Design and Operation of Reservoirs
Due to stochastic nature of rivers, their volumetric yields are random variables. Spatial and temporal redistribution of Water makes the reservoir construction a must. Therefore, water...

Forcing Function and Climate Change
A system framework for investigating the effect of climate change in the upper Rio-Grande river basin, New Mexico, is developed. The forcing function or input into a climate change model...

The Yucca Mountain Probabilistic Volcanic Hazard Analysis Project

An Assessment of Future Volcanic Hazard at Yucca Mountain

Results of the Probabilistic Volcanic Hazard Analysis Project

Biosphere Modelling for Radioactive Waste Disposal

Use of Probabilistic Methods for Analysis of Cost and Duration Uncertainties in a Decision Analysis Framework

Probabilistic Evaluation of Postclosure Criticality Events Internal to the Waste Package

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...

Development of a Hydrologic Model with Both Spatially Distributed and Physically Based Capabilities
A distributed hydrologic model is developed at The Pennsylvania State University for use with rasterized data bases. The purpose of the Terrestrial Hydrologic Model or THM is to investigate...

Assessment and Implications of Local Channel Instability on the Prediction of Bridge Scour
Current assessments of the potential for scour at existing and new bridges do not include the effects of local channel instability on predicted bridge scour estimates. Local channel instability...

Simulation of Catchment Response Using RC Network
This paper describes a simple physically-based distributed parameter hydrologic model of catchment response using a network of capacitors and resistors. The effect of topography is modeled...

Model for Water Quality in Periphery of Distribution Systems
A model is presented for water travel time and chlorine concentration in periphery dead ends of the water distribution system. The model is developed under the premise that residential...

Tributary No. 9 Restoration, Maryland State Highway Administration
The Maryland State Highway Administration agreed to accomplish restoration of 1,100 feet of stream channel as part of a mitigation agreement with the U.S. Army Corps of Engineers, Baltimore...

Estimation of High Spring Floods Causing Inundation in Non-Studied Rivers of the West Siberian Plain
Spring flooding is the main and the most abounding in water period in flow regime of West Siberian rivers. As a result, there is powerful and wide inundation on relief of West Siberia....

Direct Measurement of Turbulence Structures in a Standard Jar Test Tank Using PIV System
Particle image velocimetry (PIV) is applied to the measurement of instantaneous two-dimensional velocity fields in a standard 2-liter jar test tank for several different impeller speeds....

An Economy and Risk Analysis of Installed Capacity Expansion at the Three Gorges Power Plant
This paper studies the possibility and economy of peak-regulation operation during flood period at the Three Gorges reservoir, which will at the same time satisfy the requirements for...
