Readme: Wombat State Forest Large Wood Loads Post-Blowdown

This resource includes two datasets: one with reach-level data (wombat_summary.csv), and one with large wood piece/jam level data (wombat_field_data.csv).

File: wombat_summary.csv
Headers:
- river: river or creek name
- reach: assigned reach number
- reach_length: longitudinal length of reach in meters
- valley_w: average lateral width of the valley bottom in meters
- hillslope_grad: average hillslope gradient in degrees
- hillslope_length: average length of hillslope from valley bottom to ridge top in meters
- aspect: azimuth aspect of hillslope in degrees
- hillslope_area_ha: area of hillslope, from valley to ridgetop, adjacent to the reach in hectares
- blowdown_area: area of mapped blowdown within the boundaries of the reach-adjacent hillslopes, in hectares
- per_bed: percentage of large wood and jams touching the channel bed within the reach
- per_broken: the percentage of large wood and jam key pieces that were broken upon impact within the reach
- woodload: volume of large wood stored as individual pieces and jams within the channel, in cubic meters
- woodload_per_100m: woodload normalized by reach length, in cubic meters per 100 m
- per_sed: percentage of large wood that is visually storing sediment
- per_water: percentage of large wood that is visually ponding and storing water
- per_store: percentage of large wood that is either visually storing sediment OR water
- sed_vol: estimated volume of sediment stored by all in-channel large wood within the reach, in cubic meters
- water_vol: estimate volume of water ponded by all in-channel large wood within the reach, in cubic meters
- avg_log_length: average length of blown down large wood on the hillslopes and in the valley bottom (remotely measured), in meters
- log_count: number of blowndown pieces of wood on the hillslopes and in the valleys (remotely measured)
- perc_blowdown: percentage of hillslope area affected by blowdown
- loghill_length_ratio: ratio of average log length to average hillslope length, in meter per meter
- logvalley_ratio: ratio of average log length to average valley bottom width, in meter per meter
- log_per_ha: number of downed logs per hillslope area, in count per hectare
- log_per_blowdown: number of downed logs per blowdown area, in count per hectare
