Abstract:
This report is a digital database package containing both plotfiles and Geographic Information Systems (GIS) databases of maps of rainfall thresholds for debris-flows in the San Francisco Bay Region, as well as the location of rain-gages and Alert-stations used in producing the model. The data are provided, only for the region as a whole, in two formats. The data are provided as ARC/INFO (Environmental Systems Research Institute, Redlands, CA) coverages and grids for use in GIS packages, and as PostScript plotfiles of formatted maps similar to traditional U.S. Geological Survey map products.
Quality
This is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code.
Use Constraints
Although this database has been subjected to rigorous review and is substantially complete, the USGS reserves the right to revise the data pursuant to further analysis and review. Furthermore, it is released on condition that neither the USGS nor the United States Government may be held liable for any damages resulting from its authorized or unauthorized use.
