ROCKY J. KEEHN • <br /> Water Resources Design Engineer <br /> Education: <br /> BS - Civil Engineering - University.•of Nebraska-Lincoln <br /> ( 1982 ) <br /> MS - Water Resources - Iowa State University ( 1987 ) <br /> Professional Associations: <br /> American Society of Civil Engineers - Associate Member <br /> General Background: <br /> Experience in the area of watershed management using . the <br /> computer program TR-20. Through graduate studies at Iowa <br /> State University gained. valuable knowledge in: water <br /> surface hydrology, , hydraulics, groundwater hydrology, <br /> water , resources planning, groundwater contamination <br /> movement, urban hydrology, and hydrologic computer models. <br /> Attending several . short courses sponsored by the Iowa <br /> State Engineering Extension Service to keep abreast on <br /> current hydrologic and hydraulic design techniques. <br /> Experience: <br /> Design Engineer for the Roseville, Minnesota Stormwater <br /> Management Plan A detailed study of the lakes, ponds, and <br /> marshes in the city is being made to determine the water <br /> surface elevations for the 100-year storm event. The <br /> study. addresses both present and future land use. Based <br /> on the data obtained from computer runs using the Soil <br /> Conservation Service ' s TR-20 computer program, problem <br /> areas will be recognized, reviewed and analyzed for <br /> possible solutions. The completed report with all <br /> recommendations- will be given to the city engineers so <br /> they can better handle current and future water ponding <br /> . problems. . The study included acomputer back water <br /> analysis of large trunk storm sewers acting as pond outlet <br /> to identify pipe surcharging and deficient capacity. <br /> .Pre-Doctoral Research Assistant - Iowa State University <br /> As part of a project financed by the Iowa Highway Research <br /> Board - Iowa Department of Transportation ( Iowa DOT) , <br /> developed computer spreadsheets , to do hydraulic and <br /> hydrologic calculations. Once approved by the Iowa DOT, <br /> the spreadsheets created for this project will ' be used by <br /> county engineers to design appropriate •aspects of projects <br /> approved - by the Iowa DOT. Areas designed by these <br /> spreadsheets include: calculation .-of stream discharge, • <br /> culvert design, backwater calculations, stage-discharge <br /> calculations in .natural and man-made .reaches, and normal <br /> I flow in geometric channels. <br />
