Coastal Hazards Atlas of Texas: Hurricane Surge and Shoreline Data for Southeast Coast

Volume 1 of the Texas Coastal Hazards Atlas contains geospatial data for hurricane preparedness and coastal management along the state's southeast coast. The dataset, authored by James Gibeaut and hosted by the Texas Data Repository, includes sections on bay erosion, hurricane surge modeling, shoreline projections, and environmental sensitivity. It was last updated on October 15, 2025.

Use Cases

• Modeling hurricane surge inundation areas based on computer model surge data.
• Analyzing projected shoreline erosion and accretion from 1996 to 2056.
• Mapping wetland habitats using National Wetland Inventory (NWI) data for five counties.
• Assessing land-surface subsidence trends from 1906 to 1987.

Strengths

• Contains multiple integrated hazard layers, including surge models, historic shorelines, and fault data.
• Covers a specific geographic region with data in a consistent UTM Zone 15, NAD83 projection.
• Includes temporal projections for shorelines up to the year 2056.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file sizes are unknown, which may limit suitability assessment.
• The description is structured as a table of contents rather than detailing data collection methods.
