Southeast Texas Modified Digital Elevation Models [Draft]

This is a set of Digital Elevation Models (DEMs) that were used in the work cited below. The modifications allow for flood modeling scenario generation.

Description of DEMs: SETx_10m_DEM: Original DEM* DEM_1: Includes modifications to improve baseline model DEM_2: Includes modifications from "DEM_1" & detention pond expansion DEM_3: Includes modifications from "DEM_1" & new neighborhood development DEM_4: Includes modifications from "DEM_1" & Levee development DEM_5: Includes modifications from "DEM_2" & "DEM_4" DEM_6: Includes modifications from "DEM_3" & "DEM_4"

This data supports the journal paper: Land-use analysis using infrastructure representations and high-resolution flood inundation mapping techniques https://doi.org/10.1016/j.ijdrr.2025.105518

*Baseline DEM from TNRIS: OCM Partners, 2025: 2017 TNRIS Lidar DEM: Jefferson, Liberty and Chambers, TX (East), https://www.fisheries.noaa.gov/inport/item/59008.
