Abstract : The city of Oelwein, Iowa, requested assistance from the Rock Island District, Corps of Engineers, to determine a solution for the flooding problems along a drainage ditch called Dry Run Creek within the city's corporate limits. This detailed project report presents the evaluation of alternative solutions to Oelwein's flooding problems. The report recommends the construction of a Channel Modification project which would produce annual net economic benefits of $13,800, and has a benefit-to-cost ratio of 1.6 based upon a 50-year economic life and a discount rate of 8-5/8 percent. The estimated total construction cost is $250,300, of which 130,515 is a non-Federal cost. Environmental impacts of the project are not significant and are evaluated in the environmental assessment. Keywords: Hydrology, Hydraulics; Economic analysis, Geotechnical analysis.
