This data release contains data summarizing observations within and adjacent to the Tadpole Fire, which burned from 6 June to 4 July 2020. In particular, this monitoring data were focused on debris flows triggered on 8 September 2020 in four drainage basins (TAD1, TAD2, TAD3, and TAD4). Rainfall data (1a_rain_geophones.csv) are provided in a comma-separated value (CSV) file. The columns in the csv file are: Index, GaugeID (name of rain gauge), StormID (the storm number starting at the first record, where a new storm is defined by 8 hours with no rainfall), TimeStamp (local time), Bin Accum (mm) (The total accumulated rainfall between timesteps in units of millimeters), TotalAccum (mm) (the cumulative rainfall starting from the beginning of the record), 5-minute Intensity (mm/h) (the 5-minute rainfall intensity), 10-minute Intensity (mm/h) (the 10-minute rainfall intensity), 15-minute Intensity (mm/h) (the 15-minute rainfall intensity), 30-minute Intensity (mm/h) (the 30-minute rainfall intensity), and 60-minute Intensity (mm/h) (the 60-minute rainfall intensity). The location of the rain gage is: 32.955, -108.232. Rainfall data (1b_rain_only.csv) are provided in a comma-separated value (CSV) file. The columns in the csv file are: Index, GaugeID (name of rain gauge), StormID (the storm number starting at the first record, where a new storm is defined by 8 hours with no rainfall), TimeStamp (local time), Bin Accum (mm) (The total accumulated rainfall between timesteps in units of millimeters), TotalAccum (mm) (the cumulative rainfall starting from the beginning of the record), 5-minute Intensity (mm/h) (the 5-minute rainfall intensity), 10-minute Intensity (mm/h) (the 10-minute rainfall intensity), 15-minute Intensity (mm/h) (the 15-minute rainfall intensity), 30-minute Intensity (mm/h) (the 30-minute rainfall intensity), and 60-minute Intensity (mm/h) (the 60-minute rainfall intensity).The location of each rain gage station is: 32.956, -108.241. Geophone data (2_geophone.csv) are provided in a comma-separated value (CSV) file. The columns in the csv file are: TimeStamp (local time), GeophoneUp_mV (the upstream geophone data in millivolts), GeophoneDn_mV (the downstream geophone data in millivolts). The geophones are co-located with a rain gage at: 32.955, -108.232. Field measurement data (3_combined_data.csv) are provided in a comma-separated value (CSV) file. This dataset describes pieces of wood found within different debris flow deposits in four drainages TAD1-TAD4, and there were multiple debris flow deposits in each drainage. The columns in the csv file are: ID (a unique identifier for each wood piece). For example, if there is one piece of wood at a location in the channel TAD1, the wood piece was mapped as TAD1-1. However, in the case of a single debris flow deposit with multiple pieces of wood, a letter is appended for each additional wood piece, such as TAD1-1a, TAD1-1b, TAD1-1c, etc.), ID_base (a unique identifier for each deposit, which may contain multiple wood pieces), Latitude (the Latitude expressed in Decimal Degrees), Longitude the Longitude expressed in Decimal Degrees), Elevation (the elevation expressed in meters), Length (m) (the length of a wood piece in meters), Diameter (cm) (the diameter of the approximate middle of a wood piece in centimeters), Class (a description of the wood piece), Charred (%) (the percent of the wood piece that was charred by fire), Trapped Sediment (m3) (the total volume of sediment in a debris flow deposition cubic meters), Timing (this is a description of when the wood was deposited with respect to the debris flow. The options are Before, During, or After), Pinned (this indicates wood was pinned against an obstacle or not. If it is pinned, the item is named, otherwise it is labeled as no), Roots/Branches (here indicate either if the roots or branches where still attached to the wood, otherwise it is labeled as no), Orientation (in some locations, the qualitative orientation of the wood with respect to the flow direction is noted), Channel Width (m) (measurements of channel width in meters), Flow Depth (m) (measurements of flow depth in meters), Slope (deg) (the slope value in degrees obtained by selecting the raster slope value from a 1 m lidar underneath the observation point), Lidar Width (m) (the channel width in meters measured 1 meter above the lowest point in the channel), Drainage Area (m2) (the upstream contributing drainage area for at each measurement point), Notes (any notes from the site). Photographic data (4_GameCameraPhotos.zip) are presented from a camera located approximately 25 m from the geophones, focusing on the channel monitored by the geophones. The photos are in a .jpg format and are catalogued by date using the date format (ddMMMYYYY).
