<br />m <br /> <br />030:) <br /> <br />John N. Winchester <br />Water Resources Engineer <br /> <br />Education: <br /> <br />Master of Science in Civil Engineering <br />Specializing in Hydraulics <br />Colorado Srate University <br /> <br />Bachelor of Science in Watershed Sciences <br />Colorado State University <br /> <br />Gronning Engineering Company: <br /> <br />Mr. Winchester performs technical appraisals of water rights, water-supply studies, and design and <br />operarions analyses of complex, integrated water resource systems, Performs hydrologic studies including <br />watershed yield analysis, reservoir siting and sizing, storm water drainage and drought severity-frequency <br />analyses. Develops and programs computerized models to simulate river basins, irrigation systems, <br />municipal raw water nerworks, reservoir operations, water exchanges, and water right accounting. <br /> <br />Mr. Winchester has performed hydraulic design for open channel and closed conduit flow. ConstrUcted <br />detailed engineering studies relating ro surface and groundwater hydrology. Administrator for cornpany <br />m'crocomputors. He !>.as written :md used computer programs for Ending hydraulic condit\ons, including <br />normal and critical depth, warer surface elevations and backwater curves. <br /> <br />Prior Expenence: <br /> <br />Performed lield water and sediment discharge measurernents. Measured water quality and did lab work for <br />suspended sedIment, total dissolved solids (TDS), di>solved oxygen, pH, soil and fecal coliform counts. Soil, <br />plant, bovine blood and fecal sampling. <br /> <br />Project Experience: <br /> <br />FRYlNGP.'\.l'l-ARKANSAS RlVER BASIN OPERATIONS STUDY, CO u Provided services to com'en data to a <br />matching cornputerized format, and developed to rnodels for the project. To evaluate projecr operations and <br />alternatives for raw water storage for the City of Colorado Springs. He verified results confirming they were <br />identical to those completed by USBR on Cyoer by conducting calibration runs using a 1966-1985 data set. <br />A subroutine to include agricultural uses and to provide an exchange accounting method. A complete 58- <br />year record was made in a shorter time period that significantly reduced the cost to the City than if the <br />ontire data set had been recreated. Also. the GEC daily flow exchange model to include area downsn-eam. <br /> <br />TOWAOC CANAL REACH 3 AND LATERALS, DOLORES PROJECT, CO -- Assisted in design ofrnore than SO <br />irrigation canal cross drainage strUctures. This included culvert sizing, inlet and outlet erosion protection, <br />determination of hydraulic conditions above. below and in the cross drainage, interceptor ditches, and fmal <br />grade of the eanhwork. Involved in sizing and placement of baffled outlets, riprap, and inlet and outlet <br />strUctures, Provided geomorphologIc study of buried siphon and pipeline drainage crossings, and hydraulic <br />review of turnout srructures. <br /> <br />CHURCH DITCH COMPANY. CO n Performed survey work and necessaty calculations to determine the <br />backwater curve above several culvens. This water elevation was used in the siting of a new pedesuian <br />bridge over the ditch. <br />
