Friction Slope Computation for Mathematical Models
The behavior of the energy flow gradient as function of depth and velocity is analyzed for three flow resistance methods. In the paper, the necessary modifications introduced to the methods...
Comparison of
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...
Highway Erosion Remedial Measures
Soil erosion from highway ditches, cut slopes and fill slopes present a continuous problem to roadway designers, geotechnical engineers, and construction and maintenance personnel from...
Method to Predict Cropland Ephemeral Gully Erosion
The U.S. Soil Conservation Service (SCS) in cooperation with the Agricultural Research Service (ARS) has developed a microcomputer program to provide estimates of the average annual material...
An Overview of Computer Stream Sedimentation Models
This paper discuss some of the author's experience in computer modeling of stream sedimentation problems. Comparisons of twelve selected models developed and implemented in...
Modeling Erosion and Deposition Due to Suction and Jet Flows
PHOENICS, a commercial 3-D computational fluid dynamics software package, was modified for simulating seabed erosion and deposition. Time varying sediment fluidization, transport and deposition...
The Relationship of Milligrams Per Liter to Parts Per Million
Derivations of the relationships between mg/l and ppm are presented. Although forms of these relationships can be found in scattered references, the author's intent is to...
Prediction of Time Development of Local Scour
The prediction of the time development of local scour is commonly solved by means of model tests. A brief description of the time-scale and the relation between the time and the scour...
Estimating Velocity and Scour in River Bends
A one-dimensional, steady-state, stream tube model was used to simulate hydraulic characteristics at a cross section. This enabled computation of higher velocities on the outside and lower...
Limitations of Modeling High Concentration Streams
Following the 1980 eruption of Mount St. Helens, high sediment concentrations caused rapid deposition and increased flood hazards along the Cowlitz River. The Corps of Engineers developed...
On the Selection of Sediment Transport Equations
Certain aspects of the selection of equations to use in the calculation of sediment transport in streams are examined in this paper. The use of a critical discharge is examined and problems...
Background and Applications of Fluvial-12
The computer program FLUVIAL-12 is formulated and developed for water and sediment routing in alluvial channels. The combined effects of flow hydraulics, sediment transport and river channel...
On Sediment Transport Modeling
Basic elements of a comprehensive water-sediment model are hydraulic, sediment, and morphologic computations. The stream tube approach and minimum energy dissipation rate theories are...
STUDH: A Two-Dimensional Numerical Model for Sediment Transport
TABS-2 water level and flow computations are performed by the generalized numerical model program RMA-2V; salinity and tracer transport computations are performed with RMA-4, and sediment...
Laboratory Analysis of Hyperconcentrations
The physical and kinematic behavior of hyperconcentrations has been reviewed and a summary of recent and past developments in hyperconcentrated flow research is presented. This paper focuses...
Settling Basin Model for the Personal Computer
The SETSIZE program, models sediment deposition in a settling basin. The program can be applied to determine the length of time until dredging or cleaning is necessary or solve for an...
Soil Erosion and Sediment Transport Modeling on Small Tropical Watersheds
A fundamentally-based concept of a soil erosion and sediment transport model in a forest tropical area is presented. It will be incorporated to the ANSWERS model. The forest hydrology...
A Watershed Model of Sediment Transport?Load-I
A watershed sediment transport model has been formulated and optimized upon storm hydrographs and the associated sediment load data for several watersheds that have been urbanized and...
A Computer Model for Gravel Pit Headcut Simulation
Sand and gravel mining activities have led to numerous problems in river management. A review of many complaints on sand and gravel mining indicates that the major concern is structural...
Sedimentation in Mud Mountain Reservoir at High Discharge
Mud Mountain Dam is a single purpose flood control project completed in 1948 on the White River in the State of Washington. The White River drains the northern and northeastern slopes...
