Michigan Hydrologic Calculation Procedures

The Federal Highway Administration (FHWA), the Michigan Department of Environment, Great Lakes, and Energy (EGLE) and the Michigan Department of Transportation (MDOT) reviewed the approved procedures for calculating discharges from simulated Michigan rainfall events. The current hydrologic methods rely on older data sets and new data is available for consideration. While EGLE and MDOT understand how these procedures need to be updated, limited staff resources are focused on critical assessment tasks and cannot be diverted to quickly update these methods. The updating of these methods is critical because discharges are currently used to assess flood conditions for mapping, conveyance design, and flood mitigation. EGLE and MDOT have a desire to incorporate modern data sets into existing methodologies to improve calculated discharge results.
