Advection-Diffusion Calibration of Dissolved Oxygen
Modifications of J.J. Leendertse's water-quality model for improving calculations of dissolved oxygen concentrations in Jamaica Bay, New York, are discussed. Changes to the...
Contaminant Loading from Fox River to Lower Green Bay
The heavily industrialized lower reach of the Fox River, downstream of the DePere Dam, and lower Green Bay, Lake Michigan, are modeled. Hydrodynamics and contaminant transports to the...
Three-Dimensional Modeling of Pollutant Transport
A numerical model for pollutant transport in coastal waters has been developed in x-y-z-t space. The simplicity of a fixed Eulerian mesh and a computationally efficient Lagrangian approach...
2-D Particle Tracking Model for Estuary Mixing
This paper presents the development and analysis of a 2-D particle tracking or random walk model for the simulation of transport in vertically well-mixed estuaries. The model was tested...
Model Comparisons of Oyster Recruitment in Delaware Bay
A second order particle trajectory model using surface currents from a three-dimensional model of Delaware Bay was run for a period equivalent to the larval stage of the oyster C. virginica...
Data-Collection Program for Pamlico River Estuary Model Calibration and Validation
An investigation is being conducted to collect and interpret continuous records relating to the flow characteristics of the Pamlico River Estuary, North Carolina, and to calibrate and...
Recent Progress on Hydrodynamic Modeling of San Francisco Bay, California
A hydrodynamic modeling study of the effects of freshwater inflow on circulation and mixing in San Francisco Bay has been underway since 1985. This paper describes the multidimensional...
Multi-Dimensional Modeling of Hydrodynamics and Salinity in San Francisco Bay
This paper presents a modeling study of salt intrusion into San Francisco Bay that used a three dimensional finite element model capable of different approximation levels in different...
Comparison of Computed and Observed Velocities at Three Estuarine Sites
The Generalized, Longitudinal-Vertical Hydrodynamic and Transport model (GLVHT) has been applied to the Patuxent River estuary, the Raritan River Estuary and the Arthur Kill. The applications...
Microwave Remote Sensing of Soil Moisture Applied to Hydrologic Modeling
Recent advances in microwave remote sensing have demonstrated the ability to measure soil moisture under a variety of topographic and vegetation cover conditions; however, its application...
SLURP: A Watershed Model for Satellite Data
A study is being conducted to determine the utility of satellite data for hydrologic modelling in different physiographic and climatic zones of Canada. As part of that study, a simple...
An Application of Remote Sensing to Distributed Hydrologic Simulation
Hydrologic processes affecting flood flows occur primarily at the surface of the earth. Furthermore, the role of vegetation on the hydrologic response is very important in flood flow forecasting....
Chaotic Characteristics of Snowmelt Runoff: A Preliminary Study
Chaos, the study of nonlinear dynamic systems, offers a way of observing order in systems previously thought to be random. In this study, we analyze snowmelt runoff from a small watershed...
Method to Predict Cropland Ephemeral Gully Erosion
Erosion of farmlands due to concentrate flow is very severe on many unprotected fields across the county. Small channels can you in large gullies of not controlled. These small channels...
Simulating Runoff and Sediment Yield on Semiarid Watersheds
This paper describes a computer program called WESP (Watershed Erosion Simulation Program), a physically-based, distributed parameter, event-oriented, one-dimensional numerical model for...
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...
An Interactive Computer Model to Simulate Water Quality of Streamflow from Forested Watersheds in Arizona
To better formulate water resources policies and management strategies, a computer model that simulates concentrations of dissolved chemicals in snowmelt-runoff from forested watersheds...
Hydrologic Effects of Brush to Grass Conversion
A physically based rainfall-runoff model is used to detect hydrologic response to artifically induced vegetation changes on a semiarid watershed. Model parameters are optimized using a...
