A statewide portal that helps Texans understand their risk of land subsidence. SUBSIDE answers a single question for any location a user picks on a map — "how much is the ground sinking, observed and projected, and what's around it?" — by combining satellite-measured ground movement with a forecast screening model over context layers from the TWDB data catalog.
Three engines:
- Observed — Ground movement measured from NASA OPERA DISP-S1 satellite radar (InSAR), showing how much and how fast the land has actually moved.
- Forecast — An aquifer screening model that projects future subsidence and produces a 0–10 risk score.
- Context — Spatial layers (aquifers, wells, frame availability, and more) served as interactive map layers.
SUBSIDE is led by the Texas Water Development Board (TWDB) with UT Austin and the Texas Advanced Computing Center (TACC), supported by the USGS, with research collaborators WERC and the H2I Lab (UT Arlington).
