Frying Pan avalanche data

The data here are large wood data collected in the Summer of 2022 in the Frying Pan River Basin in the Sawatch Mountains of Central Colorado. There are six datasets included or referenced here. The first is general geomorphic and watershed characteristics of the stream reaches surveyed.  The second is data from field reports to the CAIC. The third is topographic data for the studied avalanche pathways. The fourth is summary data of the wood volumes within each surveyed reach. The fifth is the unprocessed raw data for all wood jams and individual pieces surveyed. The sixth is a table of literature-derived annual recruitment rates for mechanisms common to mountain streams. Data may also be accessed via the Dryad data repository as linked in the data accessibility statement.
Raw data relate several wood jam and individual piece properties, including length, width, and depth of the former, and length and diameter of the latter. Data also indicate several other wood characteristics, such as ..., Raw data were collected in the field by two trained observers. Wood loads were measured in the field using a census approach for all wood jams and individual wood pieces within the bankfull channel. Jams were identified as accumulations with three or more contiguous pieces; jam volume was quantified by measuring the length, width, and height of a rectangular prism fit to the dimensions of the jam and visually estimating porosity. Porosity was consistently estimated by two independent observers to minimize systematic bias. For individual wood pieces, diameter and length were measured and then used to compute volume via the formula of a cylinder. All measurements were made for wood at least partially contained within the bankfull channel, which was visually estimated in the field using topography (e.g., slope breaks). For wood pieces or jams that extended laterally beyond the bankfull dimensions, those portions outside were excluded from measurements. Measured wood loads were normalized b..., CSV files can be opened by all software. , # Frying Pan Avalanche Data

The data here are large wood and geomorphic characteristic data collected in the Summer of 2022 in the Frying Pan River Basin in the Central Mountains of Central Colorado, avalanche report data collected from the Colorado Avalanche Information Center website (avalanche.state.co.us), topographic and vegetation summary data derived from USGS Elevation Products (apps.nationalmap.gov/downloader/) and LANDFIRE (landfire.gov), and data derived from a meta-analysis of the large wood literature. Data were collected to examine research questions related to in-stream wood load volumes supplied by snow avalanches and the resultant geomorphic impacts.

There are nine datasets here. Below we detail the data formatting specifics for each file. Note that data in each file are formatted in \"long\" format for easy use with statistical software. NAs in all datasets mean that the measure in question was inapplicable to the parameter under consideration.
