Description
Hydrology data include spatial datasets and data tables necessary for documenting the hydrologic procedures for estimating flood discharges for a Flood Insurance Study, which include the hydrologic data expected by FEMA for new riverine studies. (Source: FEMA Guidelines and Standards for Flood Risk Analysis and Mapping) Recent innovations and efficiencies in floodplain mapping have allowed FEMA to develop processes called Large Scale Automated Engineering and Base Level Engineering, which can be used to address current program challenges including the validation of Zone A studies and the availability of flood risk data in the early stages of a Flood Risk Project. The Large Scale Automated Engineering and Base Level Engineering processes involve using best available data and automated techniques to mass produce estimates of flood hazard boundaries for multiple flood recurrence intervals.
