100-Year Floodwater Depth Model of Arkansas

<b>100-Year Floodwater Depth Model of Arkansas</b>
<br><br>
Floodwater depths across Arkansas modeled using the Google Earth Engine (GEE; Gorelick et al. 2017) implementation of the Floodwater Depth Estimation Tool (FwDET-GEE; Peter et al. 2020). FwDET was developed by Cohen et al. (2019) and uses an elevation model and flood boundary data to create a continuous flood depth surface. NASADEM and EnviroAtlas were used as inputs here (NASA JPL 2020; Woznicki et al. 2019). An associated manuscript on the spatial relationship between floods and socioeconomic characteristics is currently in preparation (Peter et al. forthcoming). Support provided by Arkansas NSF EPSCoR Track 1 (OIA-1946391).
