  • Linear Programming for Flood Control on the Iowa and Des Moines Rivers
    LINEAR PROGRAMMING FOR FLOOD CONTROL IN THE IOWA AND DES MOINES RIVERS By Jason T. Needham,1 David W. Watkins Jr.,2 Jay R. Lund,3 Associate Members, ASCE, and S. K. Nanda,4 Fellow, ASCE ABSTRACT: This study addresses questions related to ¯ood-control operating procedures followed by the U.S. Army Corps of Engineers, Rock Island District. Application is presented of a mixed integer linear programming model for a reservoir system analysis of three U.S. Army Corps of Engineers' projects on the Iowa and Des Moines rivers. A strategy for evaluating the value of coordinated reservoir operations is developed. Results of this study suggest that operating Coralville Reservoir, on the Iowa River, for ¯ood control on the Mississippi River does not provide appreciable bene®ts and, therefore, an operation plan coordinating releases from Cor- alville Reservoir with the two reservoirs on the Des Moines River may be unnecessary. Damage-minimizing results were obtained by operating the three reservoirs independently for 8 of the 10 largest ¯ood events on record. Also, a review of the operating procedures for the ¯ood of 1993 illustrates how much damage could have been reduced if in¯ows could be predicted months in advance or if the existing operating rules were more averse to extreme ¯ood events.

  • Geologic History of Johnson County, Iowa: an Emphasis on the Devonian Fossil Gorge
    Geologic History of Johnson County, Iowa: An Emphasis on the Devonian Fossil Gorge By Lindsey Downes and Shannon Wilson Table of contents Abstract Page 2 Introduction/Statement of Purpose Page 2 Geography Pages 2­7 Economic Resource of Johnson County Page 8 Geology and Theme Page 9 References Pages 10­11 1 Abstract This following paper summarizes the geological history of Iowa and in particular Johnson County. Details can be found on the types of bedrock found in Iowa and common fossils found in Johnson County. Specific attention is given to the Coralville Lake area in Coralville, Iowa and the Devonian Fossil Gorge. The Devonian Fossil Gorge is an impressive formation displaying several fossils preserved in Devonian rock and gives an unique insight into what the ecosystem of that time period was like. The fossil gorge is later included as part of a middle school science lesson on geology, classification and ecology. Introduction ­ Statement of purpose ​ ​ The central focus of this paper is on the Devonian Fossil Gorge in Coralville, Iowa. The main focus of the student project will be identification of fossils found in the Devonian Fossil Gorge and making ecological connections between the organisms and their environment. Students will need to understand the geologic history of the Johnson County, historical flooding events that have helped to uncover the Devonian Fossil Gorge, and the organisms that existed during the Devonian Time Period. Geography Johnson County is located in Southeast Iowa (see Figure 1) and was settled in 1836. According to the United Census Bureau, the most recent estimated population of Johnson County, Iowa is 144,251 people (U.S.
