Application of RUSLE to Rangelands
The Universal Soil Loss Equation (USLE) has been revised to more accurately estimate soil loss from both crop and rangeland areas. Major revisions affecting rangeland soil loss estimates...
Assessing Nonpoint Pollution Potential of Surface Waters Using a Geographic Information System
The use of Geographic Information Systems (GIS) to determine the susceptibility of surface waters to nonpoint pollution is described. The Geographic Resources Analysis Support System (GRASS)...
Utility of a GIS in Watershed Management?A Case Study
A geographic information system data base was established for a small watershed in Shelby County, Tennessee, for both surface and subsurface water attributes. The surface water portion...
An Integrated GIS and Model for Assisting the Managers of an Army Training Area
The ARC/INFO geographic information system (GIS) has been combined with the ARX spatial expert system and the SMSP soil moisture-soil strength model to assist the managers of a major training...
Sediment Production from Forest Roads with Wheel Ruts
Artificial rainfall was applied to two sets of paired plots 30.5 m long by 1.52 m wide, each set on a different soil type. One plot in each set contained a wheel rut while the other did...
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...
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...
Soil Moisture Measurements in Oil Shale Waste Material Using a Neutron Probe and Time Domain Reflectometry
Five large scale lysimeters (7.3 ? 3.0 ? 3.0 m deep) have been constructed to collect information and data on hydrological factors which affect the movement of water through a large scale...
Predicting Overland Flow Response: Effects of Spatially-Varying Soil Properties
A physically-based model of Horton overland flow is applied to experimental data from a simulated rainfall event in eastern Washington. The model employs the Green-Ampt infiltration equation...
Rainfall Simulation Studies of Nutrient Export from Watersheds in Arizona and New Mexico
Data from rainfall simulation experiments conducted in Arizona and New Mexico were used to identify relationships between total suspended sediment (TSS) concentrations (kg/ha/mm of runoff)...
Validation of Hydrophysical Components of a One-Dimensional Lake Model
A dynamic one-dimensional lake model has been developed in alternative structures, MINLAKE and FRMPND, for water-quality control strategies and lake eutrophication studies. Hydrophysical...
AGNPS: A Tool for Watershed Planning
The AGNPS model was developed to provide a means of assessing water quality impacts from agricultural watersheds. AGNPS simulates sediment and nutrient transport from the headwaters to...
Effects of Mining, Grazing, and Roads on Sediment and Water Chemistry in Birch Creek, Nevada
Assessment of the cumulative effects of mining and other land uses on water quality of Birch Creek showed that mine dumps and roads increased fine sediment deposits in some reaches. Fines...
Watershed Condition and Riparian Health: Linkages
This paper discusses linkages between riparian areas and their contributing watersheds and how using this knowledge will enhance overall watershed management success. The paper presents...
Watershed Planning in Western Pennsylvania?A Case Study
This paper presents and describes the watershed planning activities being pursued in Allegheny County, Pennsylvania. The regulatory, institutional, and technical framework of the planning...
Comprehensive Watershed Management Planning?A Case Study - The Magothy River
As a means of preserving and improving the water resources of Anne Arundel County in the State of Maryland, the County government undertook a comprehensive watershed management program....
Biodiversity in Riparian Communities and Watershed Management
Riparian communities are demonstrated to be regional centers of biodiversity and biomass. Examples are taken primarily from bird and lizard communities in the Southwest, since these vertebrates...
Stream Bank Stability Prediction for C6 Stream Type Reconstruction
A hydraulic model investigation will be conducted to evaluate the effects of root system characteristics of three meadow plant communities on simulated bank erosion. The test will determine...
Modeling Erosion and Effects of Agricultural BMP's on a West Tennessee Watershed
The application of Hydrological Simulation Program FORTRAN (HSPF) to nonpoint source data was examined. The model is used to determine the effects of land management practices upon surface...
ROTO?A Continuous Water and Sediment Routing Model
A model called ROTO was developed to estimate water and sediment yields on large basins (several thousand square miles). ROTO is a continuous model operating on a daily time step that...
