Energy Dissipation for a RCC Stepped Spillway
A two-dimensional physical model study was used to quantify the kinetic energy dissipation of the steps in a roller compacted concrete (RCC) stepped spillway. The steps were effective...
Force and Pressure Measurements in Spillway Plunge Pools
Plunge pools are often used to dissipate energy from high head spillways with flip bucket terminal structures. Conventional design of plunge pools has been based on a program of mobile...
Unsteady Spillway Inlet Conditions at the Weatherford Water Supply Reservoir
The Weatherford Water Supply Reservoir, in Weatherford, Texas has had frequent lake-side flooding and has experienced unstable spillway operation. Residents complained that the water had...
Stratified Flow in an Impounded Inland River
Stratified flow in the Seneca River of central New York is described. This flow condition occurs in the vicinity of the outflow from saline Onondaga Lake, and exists both upstream and...
Verification of a Three-Dimensional Model of Delaware Bay
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
Use of FESWMS-2DH for the Attaway Road Bridge Repair Project
The paper presents the application of the Finite Element Surface Modeling System: Two Dimensional Flow in a Horizontal Plane (FESEMS-2DH) computer program in the Attaway road bridge repair...
A Wind Driven Lake Circulation Finite Element Model for the Upper St. Marys River
The hydrodynamics of the Upper St. Marys River is simulated by a three dimensional steady state finite element model. The rigid lid and hydrostatic pressure assumptions are used in the...
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...
Climatic Perspective on the 1993 Mississippi R. Flood
The 1993 summer flooding in the Upper Mississippi River Basin was the most devastating flood of modern times with damage estimates in the range of 15-20 billion dollars. The paper describes...
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...
Monitoring and Modeling the Transport of Coarse Single Particles in Mountain Rivers
The dynamics of single cobbles was studied in the alpine river Lainbach using the Magnetic Tracer Technique (MATT) and radiotransmitters (PETSY = PEbble Transmitter SYstem). Our measurements...
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...
