HEC-FIA

The Hydrologic Engineering Center's (HEC) Flood Impact Analysis (HEC-FIA) software is a tool to help identify the consequences from a single event. HEC-FIA was developed by HEC in collaboration with the Risk Management Center (RMC) and the Engineering Research and Design Center (ERDC). HEC-FIA evaluates consequences from events defined by hydraulic model output such as gridded data (e.g., depth and arrival time Grids) or HEC's Data Storage System (HEC-DSS) Stage Hydrographs. The consequences HEC-FIA computes include economic losses (losses to structures and their contents), agricultural losses, and expected life loss from these hydraulic events.

Title Description Standard Variables
Inundation Data Includes Max Depth, Arrival Time, Duration, and Floodway (Max Depth * Velocity) Data []
Geographic Data Geospatial Boundaries such as watershed boundary and Emergency planning zones []
Inventory Data Structure, Vehicle, Agricultural, Infrastructure, Direct Economic Damages and Loss of Life data []
Warning Issuance Scenario In HEC-FIA the warning issuance defines the moment a warning is issued to the population at risk. The issuance of warning can be generated as the result of a hydraulic event (e.g. the exceedance of a specified stage at a particular location or appearance of water on the interior side of a levee) or the passage of an amount of time in the model simulation (e.g. thirty minutes after the start of the simulation). A lag can be specified to simulate the time between the physical occurrence of the event and the human response of issuing a warning in response to that event. If the user defines a warning issuance relative to a rule that uses a specific location and threshold, the warning issuance is dependent upon a particular inundation configuration and hydraulic event. If the user defines a warning issuance relative to start time, the warning issuance works with any alternative, and is dependent upon the start time of the time window used in the simulation. []
