Extreme Rainfall Flood Projection for 2050 (Near-Term) Drainflow Scenario (Inundate!)
raster digital data
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This future rainfall scenario for 2050 (Near-Term) was developed to support the ARPC Region (Calhoun, Franklin, Gadsden, Gulf, Jackson, Jefferson, Leon, Liberty, Wakulla counties) vulnerability assessments and climate resilience planning. The scenario (2050-Near-Term vector dataset in this case) represents a statistically derived 100-year, 24-hour rainfall event for 2050 (Near-Term Scenario) as a future time horizon. This raster dataset simulates rainfall-driven inundation under changing climate conditions and is intended for use in identifying flood-prone areas, supporting infrastructure adaptation planning, and enhancing community flood resilience strategies. The flood type is this dataset was modeled as Drainflow to represent overland and fluvial flow from extreme precipitation. Projection / Coordinate System / Datums: Horizontal Datum: NAD83/2011 and Vertical Datum: NAVD88 Raster Type: Continuous surface (flood depth measured in feet)</SPAN></P></DIV></DIV></DIV>
This dataset includes modeled flood depth vector files representing hypothetical 100-year, 24-hour extreme rainfall scenario for the year 2050 across the ARPC Region (Calhoun, Franklin, Gadsden, Gulf, Jackson, Jefferson, Leon, Liberty, Wakulla counties) as Near-Term. Using the Inundate! tool, flood inundation is characterized as Drainflow (fluvial flooding from rainfall and overland flow) category for 2050 (Near-Term). The output is provided as continuous raster surfaces, with values representing flood depth in inches ranging from shallow to deepest.
The model was developed by using Inundate! tool designed by FlynnMetrics LLC in coordination with Regional Planning Councils in Florida (ARPC, CFRPC, ECFRPC, ECRC, NCFRPC, NEFRC, SFRPC, SWFRPC, TBRPC, TCRPC).
