Iowa Department of Transportation Riverine Infrastructure Database | Iowa

WHKS performed hydraulic analysis for 26 individual sites in the Upper Cedar River Watershed. The analysis made use of existing LiDAR and GIS data sets to determine approximate 100-year flood elevations for the use of an Iowa DOT early warning system. The analysis required the creation of 3-D terrain models and the conversion of other digital data into GIS format. The data was processed and designed to be compatible with existing Iowa DOT data sets.
