  • Abstract:
    A network of 25 sonic stage sensors were deployed in the Squaw Creek basin upstream from Ames Iowa to determine ; if the state-of-the-art distributed hydrological model CUENCAS can produce reliable information for all road crossings ; including those that cross small creeks draining basins as small as 1 sq. mile. A hydraulic model was implemented for the ; major tributaries of the Squaw Creek where IFC sonic instruments were deployed and it was coupled to CUENCAS to ; validate the predictions made at small tributaries in the basin. This study demonstrates that the predictions made by the ; hydrological model at internal locations in the basins are as accurate as the predictions made at the outlet of the basin. ; Final rating curves based on surveyed cross sections were developed for the 22 IFC-bridge sites that are currently ; operating, and routine forecast is provided at those locations (see IFIS). Rating curves were developed for 60 additional ; bridge locations in the basin, however, we do not use those rating curves for routine forecast because the lack of accuracy of ; LiDAR derived cross sections is not optimal. The results of our work form the basis for two papers that have been ; submitted for publication to the Journal of Hydrological Engineering. Peer review of our work will gives a strong footing to ; our ability to expand our results from the pilot Squaw Creek basin to all basins in Iowa.
