Prairie du Pont Levee and Sanitation District - Internal Levee Drainage Evaluation

April, 2008 - In conjunction with the FEMA recertification of the Prairie du Pont and Fish Lake levees along the Mississippi, comprehensive modeling of the watersheds riverward of the levee was completed using HEC-HMS. The 31.5 square mile (20,000 acre) watershed was evaluated using 25 sub-basins to determine the 100-year floodplain for all tributaries within the watershed. The results of the HEC-HMS model were used as input for an unsteady flow hydraulic model using HEC-RAS. The unsteady flow component was used to ensure accurate modeling of reverse flow in the Fish Lake tributary caused by the limitations of the Fish Lake pump station capacity and upland tributary storm impacts. 27 bridges and culverts were included in the hydraulic model to ensure impacts due to storage were properly evaluated. The discharge from new relief wells to control underseepage was incorporated into a proposed conditions model to ensure adequate capacity was available at the pump stations and gravity drains. All requisite field survey and reconnaissance was completed in conjunction with the inspection of the hydraulic structures.

Caterpillar, Inc. - East Peoria Plant Stormwater and Industrial Waste System Modeling

January, 2008 - The Caterpillar East Peoria plant consists of over 1200 acres. Numerous areas were experiencing surcharging through the storm water and industrial waste systems (IW). Comprehensive field surveys were completed to determine accurate configurations of each system including inlets, pipe characteristics, pumps, detention areas and outlet conditions. Detailed models were developed to evaluate the existing systems (stormwater and IW) to identify the likely causes of the surcharging and flooding. The modeling involved using specialized software, "STORMNET", to analyze sub-basins for each of the over 300 inlet areas to allow the determination of the hydraulic grade line throughout the entire system. The modeled systems included over 500 individual pipe components along with the downdrains from the roof structures of the major buildings on site. Included in the modeling was the determination of the time of concentration for each sub-basin and pertinent land use run-off parameters which were used to develop the applicable unit hydrograph parameters. The results of the existing conditions models were used to recommend improvements to the system to alleviate surcharging problems.

FAP 600 (IL 159) Over Canteen Creek – Madison and St. Clair Counties, Illinois

Design of the widening of a seven-span curved composite steel beam structure. Structure consists of a 76 meter four-span unit and an 81 meter three-span unit with piers and abutments at different skews. Project posed some complex geometric calculations due to the different skews of the supports, a vertical curve, and a horizontal curve with superelevation transitions at both ends. A multi-modal spectral analysis seismic design was required due to the high degree of curvature, number of spans, and bedrock acceleration coefficient.
