Summary
U. S. Geological Survey (USGS) scientists completed a data collection campaign from the 26th of June to the 13th of August in 2021, using various methods to record geomorphic and habitat indicators throughout streams in the Shenandoah Valley. Field methods included GNSS surveys, gravelometer-based pebble count readings, visual assessments, and riparian analyses. This metadata record contains all raw observations from the campaign as well as numerous summary metrics to be used in model development. Those "model-ready" data can be found in Shenandoah_Model_Deliverable.csv in the parent item, while the two child items containing raw in-channel observations and raw survey data. Attached to this release is a data dictionary containing [...]

Those "model-ready" data can be found in Shenandoah_Model_Deliverable.csv in the parent item, while the two child items containing raw in-channel observations and raw survey data.
Attached to this release is a data dictionary containing general information about Shenandoah_Model_Deliverable.csv. This information can be found in the SummaryMetrics_Dictionary.csv file.

Purpose
These geomorphic and habitat data were collected as part of a larger field campaign that included water quality, surface water, macroinvertebrate, and fish sampling for evaluating the effect of agricultural best management practices on holistic stream health. For analyses using these data, it is recommended to use the summary metrics contained in the Shenandoah_Model_Deliverable.csv file, although raw data are provided if other metrics would like to be calculated by the end user.
