Rangeland Evaluation of WEPP Hydrology
The hydrology component of the Water Erosion Prediction Project (WEPP) utilizes the W.H. Green and G.A. Ampt infiltration equation to simulate the rate and volume of excess rainfall. Excess...

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...

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...

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...

Effects of Water Erosion Processes on Drainage and Irrigation Systems
This study examines the relationship between geomorphic processes and drainage/irrigation projects. It illustrates the method of geomorphic analysis by the study of a drainage project...

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...

Debris Flow Potential and Sediment Yield Analysis Following Wild Fire Events in Mountainous Terrain
The Pacific Southwest Inter-Agency Committee (PSIAC) 1968 Sediment Yield Rating Model provides a method to rapidly assess any increase in potential sediment yields following a wild fire...

Erodible Channel Models: State of the Art Review
This paper presents a review of existing modeling techniques, their physical and mathematical background, and applicabilities. Major areas of progress are outlined and difficulties are...

Channel-changing Processes on the Santa Cruz River, Pima County, Arizona, 1936-86
Lateral channel change on the mainly ephemeral Santa Cruz River, Pima County, Arizona, causes damage and has spawned costly efforts to control bank erosion. Aerial photographs, historical...

Runoff and Erosional Processes in an Arid Watershed
This paper reports the results of geomorphic, hydrologic, and hydraulic analyses that integrated a physical process computer model of rainfall/runoff processes with a geomorphic process/response...

Land Use Change and Soil Erosion Hazard in the Zambezi Basin
An experimental model for estimating soil erosion hazard in southern Africa (SLEMSA) was linked to a raster based Geographical Information System. Soil erosion hazard maps were constructed...

A Mathematical Model of Erosion and Sedimentation of Hyperconcentrated Flow in Reservoirs
The motion of the flow with hyperconcentration has its unique law. In this paper, based on the analysis of the motion of the flow with hyperconcentration of sediment and the sediment transport...

Erosion Processes in Upland Areas
After a soil particle is detached and entrained, it will be transported by the surface runoff. However, depending on the eroding and transport capacities of the surface runoff, some of...

Identification Techniques for Bank Erosion and Failure Processes
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has developed techniques to design small flood-control channels. A component of this research is the...

Sediment Concentration Measurements Below Small Headcuts
This study is designed to determine erosion rates downstream from a small headcut. The sediment concentration from a scour hole produced by a plunging jet is measured as a function of...

Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...

Can Erosion Control Meet Regulatory Standards?
An erosion control design method for rainfall/surface erosion is presented that enables the designer to determine design loads and the resulting erosion control requirements. Design loads...

Development of a Computer Aided Decision Process for Channel Rehabilitation and Watershed Enhancement Techniques
To assist the engineer in planning and design of channel stabilization measures, an expert system (CADWET) was developed using a commercially available expert system shell program. The...

Effects of Low Drop Grade Control Structure on Bed and Bank Stability
The channel response upstream of a low drop grade control structure was documented using field investigations, analysis of the engineering properties of bank materials, and repeat cross...

Evaluation of Streambank Erosion Control Demonstration Projects
The Streambank Erosion Control Evaluation and Demonstration (SECED) Act of 1974 (Section 32 of Public Law 93-251) was enacted by Congress to obtain information on costs and performance...
