    • GeoClaw model output and flood depth data for downstream flood hazards post-hypothetical asteroid impact in Dallas, TX at 15:04 UTC October 22, 2036

    Metadata Updated: October 13, 2024

    We used GeoClaw, a modeling program that simulates shallow surface flows to assess the level of risk associated with downstream flooding following an asteroid impact. Our hypothetical impact scenario was derived from the NASA PAIR 2023 PDC risk corridor: the impact is located in the Dallas-Fort Worth area of Texas (-96.9313 °W, +32.8970 °N) at 15:04 UTC October 22, 2036. We generated flood data for the six river basins that overlap with the possible hydrophobic radii associated with our hypothetical impact scenario. Since GeoClaw does not model precipitation, we used a point-source (spring) in each river basin, with the intention of converting between spring flow and rainfall rates for data analysis in future publications. Tested spring flow rates range from 2 meters/hour to 46 meters/hour at 2 meter/hour intervals with spring flow duration ranging from 1 to 3 days in each river basin, for a total of 414 GeoClaw model runs.
