Flood Discharges in the Upper Mississippi River Basin, 1993


Book Description

From mid-June through early August 1993, flooding was severe in the upper Mississippi River Basin following a wet-weather pattern that persisted over the area for at least 6 months before the flood. The magnitude and timing of several intense rainstorms in late June and July, combined with wet antecedent climatic conditions, were the principal causes of the flooding. Flood-peak discharges that equaled or exceeded the 10-year recurrence interval were recorded at 154 streamflow-gaging stations in the upper Mississippi River Basin. At 41 streamflow-gaging stations, the peak discharge was greater than the previous maximum known discharge. At 15 additional gaging stations, peak discharges exceeded the previous maximum regulated peak discharge. At 45 gaging stations, peak discharges exceeded 100-year recurrence intervals.







The 1993 Flood on the Mississippi River in Illinois


Book Description

The lessons learned from this flood focus on the performance of the levees, governmental responses, the effects of flood fighting, change in stages due to levee breaches, flood modeling, and the lack of information dissemination to the public on the technical aspects of the flood. These lessons point out information gaps and the need for research in the areas of hydraulics and hydrology, meteorology, sediment transport and sedimentation, surface and ground-water interactions, water quality, and levees. The report presents a comprehensive summary of the 1993 flood as far as climate, hydrology, and hydraulics are concerned.




Mississippi Floods


Book Description

"Each time the waters of the mighty Mississippi River overflow their banks, questions arise anew about the battle between "man" and "river". How can we prevent floods and the damage they inflict while maintaining navigational potential and protecting the river's ecology?" "The design of the Mississippi and how it should proceed has long been a subject of controversy. What is missing from the discussion, say the authors of this book, is an understanding of the representations of the Mississippi River. Landscape architect Anuradha Mathur and architect/planner Dilip da Cunha draw together an array of perspectives on the river and show how these different images have played a role in the process of designing and containing the river landscape. Analyzing maps, hydrographs, working models, drawings, photographs, government and media reports, painting, and even folklore, Mathur and da Cunha consider what these representations of the river portray, what they leave out, and why that might be. With original silk screen prints and a selection of maps, the book joins historic, scientific, engineering, and natural views of the river to create an entirely new portrait of the great Mississippi."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Effects of the 1993 Flood on the Determination of Flood Magnitude and Frequency in Iowa


Book Description

To evaluate the effects of the 1993 flood in the upper Mississippi River Basin on the determination of flood magnitude and frequency, discharges that had recurrence intervals of 10, 25, 50, and 100 years computed from data through the 1992 water year were compared with those computed from data through the 1993 water year for 62 selected streamflow-gaging stations in Iowa. On the basis of the flood-frequency analysis computed from data through the 1993 water year, a flood that was greater than or equal to a 10-year recurrence-interval discharge occurred during 1993 at all 62 gaging stations, and a flood greater than or equal to a 100-year recurrence-interval discharge occurred at 11 of the gaging stations.
