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

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...
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...
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...
Regional Flood Plain Management
A flood plain management plan for White Rock Creek in the Cities of Dallas and Plano, Texas was developed. New technologies such as three-dimensional topography, CADD, and remote sensing...
Improved Numerical Analysis of Steady Water Surface Profiles
As well as HEC-2 and similar models serve the profession, problems exist with their application. In general, inflexibility of use and inaccuracies around transitions between subcritical...
Plans for National Flood Frequency by Microcomputer
Work is underway on a planned microcomputer program that will include about 1500 prediction equations for 214 flood regions of the United States and Puerto Rico. The program will include...
SWMM Application in Indian River County, Florida
The EPA's Storm Water Management Model (SWMM) was used to simulate drainage canal system network within Indian River County, Florida. Runoff and Extran module of the PCSWMM...
