Mirus 2018 Electronic Reston, VA U.S. Geological Survey https://doi.org/10.5066/F70K27R0 This data release includes time-series data from two monitoring stations in a small drainage basin burned in the 2014 Silverado Fire, Orange County, California. One station (upper station) is located in the headwaters of the study area (33 45’39.10”N, 117 35’17.48”W, WGS84). The other station (lower station) is located at the outlet of the study area (33 45’04.61”N, 117 35’12.54”W). The data were collected between November 15, 2014 and January 14, 2016. The data include continuous 1-minute time series of rainfall and soil water content recorded at the both stations and intermittent (during rain storms) 50-Hz time series of flow-induced ground vibrations recorded by geophones at the lower station. The soil water content measurements were made at 2 depths below the ground surface (5 and 10 cm) between 2014-11-15 and 2015-04-24, and 4 depths below the ground surface (5, 10, 15, and 20 cm) between 2015-04-24 and 2016-01-14. The ground vibrations were measured by two 4.5 Hz vertical axis geophones (Geospace SNG 11D/PC902/OPEN-30m) located approximately 3 m from the channel bank and separated by 11.8 m in the streamwise direction. Details of this study are described in the journal article: McGuire, L.A., Rengers, F.K., Kean, J.W., Staley, D.M., and Mirus B.B., (2017), Incorporating spatially heterogeneous infiltration capacity into hydrologic models with applications for simulating post-wildfire debris flow initiation, Hydrologic Processes. This data set was collected as part of an effort to understand the physical processes that generate floods and debris flows after wildfire. 20141115 20160114 ground condition Complete As needed -117.5931 -117.5853 33.7623 33.7473 USGS Thesaurus USGS Geologic Hazards Science Center GHSC Landslides Hazards Program landslide hazard landslide seismology earth science geophysics wildfire fire drainage basin debris flow heterogeneous infiltration capacity infiltration capacity rainfall soil water content USGS Metadata Identifier USGS:5a0dd520e4b09af898cf0581 Geographic Names Information System (GNIS) Orange County, California none none Jason W.
