Service Description: The future rainfall scenarios were developed to support statewide vulnerability assessments and climate resilience planning. Each scenario (raster datasets in this case) represents a statistically derived 100-year, 24-hour rainfall event for two future time horizons: 2040 (Near-Term Scenario) and 2070 (Far-Term Scenario).
These raster datasets simulate rainfall-driven inundation under changing climate conditions and are intended for use in identifying flood-prone areas, supporting infrastructure adaptation planning, and enhancing community flood resilience strategies.
Flood types are modeled in two ways respectively. Drainflow: Overland and fluvial flow from extreme precipitation and Ponding: Localized pooling in low-lying terrain due to rainfall accumulation.
Projection / Coordinate System / Datums: Horizontal Datum: NAD83/2011 and Vertical Datum: NAVD88
Raster Type: Continuous surface (flood depth measured in inches)

Title: Gadsden County Extreme Rainfall Flood Projections

Comments: The future rainfall scenarios were developed to support statewide vulnerability assessments and climate resilience planning. Each scenario (raster datasets in this case) represents a statistically derived 100-year, 24-hour rainfall event for two future time horizons: 2040 (Near-Term Scenario) and 2070 (Far-Term Scenario). These raster datasets simulate rainfall-driven inundation under changing climate conditions and are intended for use in identifying flood-prone areas, supporting infrastructure adaptation planning, and enhancing community flood resilience strategies.Flood types are modeled in two ways respectively.

Subject: These datasets include modeled flood depth raster files representing hypothetical 100-year, 24-hour extreme rainfall scenarios for the years 2040 and 2070 across Gadsden County of Florida. Using the Inundate! tool, flood inundation is characterized in two categories: Drainflow (fluvial flooding from rainfall and overland flow) and Ponding (localized flooding in topographic depressions). Outputs are provided as continuous raster surfaces, with values representing flood depth in inches.
