Modeling the Impact of Uncertainty in Spatial Variability of Estuarine Boundary Conditions
Multi-dimensional numerical estuarine models that consider baroclinic forcing require the specification of both the water surface and the water density (salinity and temperature) at the...
Distributions of Return Flow in Navigable Waterways
Physical impacts of barge traffic on the riverine environment have drawn increasing attention from resource managers of the Upper Mississippi River System (UMRS). Return flow, which can...
Spatial Statistics for Rainfall Forecasts Assessment
Assessments of rainfall forecasts were developed using GIS-based spatial statistical procedures applied to calibrated radar-rainfall fields in central Oklahoma. The overall objective of...
Automated Tools for Spatially Distributed Rainfall/Runoff Modeling
A watershed modeling system (WMS) has been developed to address the needs of surface water rainfall/runoff computer simulations. WMS, developed at the Engineering Computer Graphics Laboratory...
Status Report — Task Committee on GIS Models and Distributed Models of the Watershed
In recognition of the trend toward the adoption of geographic information system (GIS) technology in analyzing hydrologic problems and the obvious applications of GIS in incorporating...
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...
Runoff Computation Using Spatially Distributed Terrain Parameters
A spatially distributed unit hydrograph is developed based on linear system theory applied to subareas or cells within a watershed Each cell has a unique unit response function independent...
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...
Flood Damage Estimates Using GIS Spatial Analysis
The catastrophic flooding in the midwest during the Summer of 1993 and in California in the Spring of 1995 resulted in flood damage estimates in the hundreds of millions to billions of...
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....
Reducing Model Study Time and Improving Reliability
Historically, the majority of effort expended in computer modeling of physical systems has gone into the numerical algorithms used in the computer programs. Other aspects of modeling have...
