Photogrammetry techniques to quantify fine-scale topography of cinder ripples were applied to a small region of interest in Sunset Crater National Monument, Arizona.
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....

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
