Staley, Dennis M. 20210115 raster digital data https://doi.org/10.5066/P91GIT04 This data release contains gridded estimates of postfire debris flow probability and magnitude for six different rainfall and wildfire scenarios in southern California. The scenarios represent the present and hypothetical future precipitation and fire regimes for the region. The results are provided for 1 km^2 cells across the study area. Data are intended to be used to spatially represent the estimates of postfire debris flow probability in southern California under different precipitation and fire regime scenarios. Calculated probability estimates in the text file contained within this data release should be joined to this raster dataset to geospatially represent the probability estimates. 20201203 ground condition Complete None planned -122.0000 -114.1200 36.0000 32.5300 Southern California ISO 19115 Topic Category biota Lithologic classification of geologic map units Debris flow USGS Thesaurus fires USGS Metadata Identifier USGS:5fc6d062d34e4b9faad8909b None debris flow wildfire southern California None.

Golden Colorado 80422 USA 303-273-8568 dstaley@usgs.gov There are no "true" values, zone IDs are abitrarily defined. Yes Dataset represent an arbitrarily numbered zone database for southern California. The purpose of these data is to join tabular data contained in the data release to spatially represent the estimates of post-fire debris-flow probability in southern California for different fire regimes and precipitation scenarios. Raster values represent the zone ID for the 1 km pixels covering the study area. These data should be used to join tabular data contained in this data release. 20201203 Raster Grid Cell 283 523 1 Universal Transverse Mercator 11 0.9996 -117.0 0.0 500000.0 0.0 row and column 1000.0 1000.0 meters North_American_Datum_1983 GRS 1980 6378137.0 298.2572221010042 ZoneID.tif Raster geospatial data file.
