One- and Two-Dimensional Analysis of Flow in Hotophia Creek, MS
A numerical experiment on the influence of a sand bar encroachment on the stream flow pattern is reported. The results of a two-dimensional analysis were compared with results of an equivalent...
A Three-Dimensional Numerical Simulation of Seasonal Flow and Salt Transport in the C&D Canal
Two seasonal-scale, three-dimensional hydrodynamic models with salt transport using CH3D-WES were constructed to represent the most critical periods of environmental concern: fishery spawning...
1993 Mississippi Record Stages and Levee Failures
Record-setting stages, flooding duration, and multiple levee failures are distinguishing features of the Mississippi River 1993 flood. The peak stages reached at stations along the Illinois...
1993 Ground-Water Flooding in the Havana Area
The Havana area in Mason County, west-central Illinois, experienced nearly continuous rises in the water table beginning in the fall of 1992 which created lakes in depressed areas. Water...
Impacts of the 1993 Flood on the Mississippi River in Illinois
The 1993 flood has now been recognized as one of the greatest floods on the Mississippi and Missouri Rivers. Its geographical extent included portions of Iowa, Missouri, Illinois, Wisconsin,...
Historical Trends in Flood Discharges on the Upper Mississippi River
Long-term streamgage records in the Upper Mississippi River Basin were analyzed using a Kendall Tau-b analysis to determine trends in flooding and average flows. Over the 130 years of...
The Miller City Levee Break and Incipient Meander Cutoff
On July 15, 1993, the flooding Mississippi River broke through a levee near Miller City, Ill., at the head of the Mississippi Embayment, approximately 55 km upstream from Cairo, Ill. Flow...
The Summer of 1993 Floods Lower Missouri River
Throughout the State of Missouri from November 1992 through July 1993, precipitation set new records, in some cases ranging as high as 200 - 400 percent of normal rain fall. Missouri precipitation...
Problems with Indirect Determinations of Peak Streamflows in Steep, Desert Stream Channels
Many peak streamflow values used in flood analyses for desert areas are derived using the Manning equation. Data used in the equation are collected after the flow has subsided, and peak...
Analysis of the Causes and Triggering Events of Disastrous Torrent Flood
A disastrous torrent flood on the Vlasina River of 26 June 1988 was of unprecedented intensity in Yugoslavia. The catchment area affected by the catastrophe covered more than 1000 km2...
Factors Affecting Accuracy of Slope-Area Discharge Determination of the September 1992 Flood in Raven Fork, Western North Carolina
For the flood of September 10, 1992, in Raven Fork, Swain County, North Carolina, a peak discharge of 460 cubic meters per second was computed by using the slope-area method. Accuracy...
Analysis of the Torrent Lava Flow Movement and Its Computations - One Example Applied Investigation of Disastrous Torrent Flood
To compute torrent lava flow is hardly an easy task. Most often it has to be determined on the basis of flood traces. In the case of phenomenon discussed, it was the only possible way...
Roughness Coefficient in Mountain Rivers
River discharge estimations require an evaluation of the river flow resistance that generally is related with Manning's roughness coefficient. The literature suggests different ways of...
Steep Constructed Stream Channels and Chutes
Research and technology transfer needs are described for steep stream channels and chutes. Iterative processes are presented for design and construction of bouldery channels and chutes...
Chezy Formula Versus Theory and Common Sense
Using the theoretical concepts of the uniform flow formula and the inverse solution of the Chezy equation it is shown that a channel shape may have considerable influence on the value...
A New Formula for Mean Velocity in Torrents
In this paper we present a new equation for mean velocity in torrents based on travel time measurements and geomorphological relations. Here, the emphasis is not on understanding the physical...
An Alternative Equation for the Mean Velocity in Gravel-Bed Rivers and Mountain Torrents
Including new field data in the slope range of torrents up to 63%, an empirical equation is developed to express the mean flow velocity in terms of the flow rate, the slope and a characteristic...
Design of Manning's-Rougness-Coefficient Study in New York State
Field-collected hydraulic data can be used to compute roughness coefficients for channels with different hydraulic characteristics. Suggested criteria for the design of a roughness-coefficient...
At-A-Site Mountain River Flow Resistance Variation
At-a-site variation in flow resistance is examined in the light of observations of an S-shaped velocity profile at relative submergences (d/D84)...
An Analysis of Flow Velocity Profiles, Stream Bed Roughness, and Resistance to Flow in Natural Gravel Bed Streams
The characteristics of 82 flow velocity profiles were analyzed from nine different gravel bed stream reaches. A statistical test of the linearity of flow velocity profiles indicates that...
