Calibration of Sediment Transport Model for the Upper End of Elephant Butte Reservoir
Elephant Butte Reservoir is located about 125 miles north of El Paso, Texas on the Rio Grande. The reservoir is approximately 35 miles long with a narrow neck, called the Narrows, about...

On Calibration of the UZ Site-Scale Model of Yucca Mountain

Simulation and Observation of ESF Tunnel Effects on Barometric Conditions

Cropping Systems on the Delmarva Peninsula to Reduce Ground Water Contamination
A total of twelve cropping systems were simulated with the GLEAMS model for nitrate leaching. A precipitation model was developed using a Markov chain model and a gamma distribution for...

Biodegradation Modeling of a Closed Landfill Site
The two-dimensional model, BIOPLUME II, was applied to the closed Becker County Landfill at Detroit township, Minnesota, to study the transport of hydrocarbons occurring at the site. The...

Impacts of Climate Change in the Missouri River Basin
The Soil and Water Assessment Tool (SWAT) is being used as a base model to simulate the Missouri River basin for prediction of the impacts of climate change on water resources in the region....

Eastern San Joaquin County Groundwater Resource Planning Model Development and Calibration
An Integrated Groundwater Surface Water Model (IGSM) has been developed for the Eastern San Joaquin County in the Central Valley of California to evaluate the future water resources management...

Eastern San Joaquin County Groundwater Resource Planning Alternative Analysis
An Integrated Groundwater and Surface Water Model (IGSM) has been developed and calibrated for eastern San Joaquin County in the Central Valley of California to evaluate future water resources...

Field Determination of Flow through a Pressure Regulating Valve
This paper presents a computer methodology to calculate flow through a pressure regulating valve for different opening percentages and a given pressure differential. The methodology is...

Telerobotic Servicing with Virtual Reality Calibration and Semi-Automatic Intermittent Model Updates

Calibration of XRF and Laboratory Analyses of Soil

Calibration and Simulation of Non-Gaussian Translation Processes

Distributed Parameter Hydrologic Modeling and NEXRAD for River Forecasting: Scale Issues Facing the National Weather Service
With the advent of NEXRAD (Next Generation RADar), the National Weather Service has the opportunity to move from current lumped parameter modeling to more of a distributed parameter hydrologic...

Calibration of a Water Quality Model Using the Influence Coefficient Algorithm
A methodology based on the influence coefficient algorithm was established for the calibration of QUAL2E reaction coefficients. It was applied to the stream sections of the South Han River...

Modeling Combined Stresses on Aquatic Ecosystems
A mechanistic ecosystem response model is being developed by incorporating exposure/response relationships for selected natural and anthropogenic stresses into an existing hydrodynamic...

Pollution Transport in Karst
A new model of pollution transport in natural streams was developed and tested. Dead zone storage is modeled as a two time constant process. This approach better matches the observed persistence...
