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...

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...

Bank Failure and Erosion on the Illinois Waterway
In 1988, bank failure and erosion on the Illinois Waterway were evaluated. Banks were inspected from the air and from a motor vessel; thirty-one sites were examined in detail. Severe erosion...

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...

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...

Water Resources Planning and Management
The proceedings of the 16th annual Water Resources Planning and Management Conference, which was held on May 22-24, Sacramento, CA, consists of four page extended abstracts for about 200...

Cold Regions Engineering
This volume contains papers that were presented at the 5th International Cold Regions Engineering Specialty Conference, sponsored by ASCE and held in St. Paul, Minnesota, February 6-8,...

Compendium of International Ocean Energy Activities
This Compendium of International Ocean Energy Activites has been designed as a resource directory of ocean energy projects in the United States...

Bullwinkle
The 1989 Outstanding Civil Engineering Achievement is an offshore oil production platform named Bullwinkle, a structure in the Gulf of Mexico that is taller than the Sears Tower, shaped...

Award for an A-Frame
The Waddell A-frame truss bridge that now stands in Parkville, Mo. was neither the longest, largest nor most all-encompassing civil engineering project of 1988. But the story behind the...

Geotechnical Aspects of River Bank Erosion
The principal geotechnical mechanisms of river bank failure are identified on the basis of extensive field investigations on many different river systems. The role of each factor depends...

Comparison of DAMBRK With DWOPER for Computing Water Surface Elevations at Stream Junctions
The National Weather Service computer programs DWOPER (Operational Dynamic Wave Model) and DAMBRK (Dam-break) are one-dimensional models using an implicit finite difference method of solution...
