Stream morphology map (DP4.00131.001)

The wadeable stream morphology data product provides raw survey data, maps, shapefiles, and metric tables that quantify stream channel geomorphology and bed composition and delineates biological habitats within the aquatic reach boundaries (approximately 1,000 meters in stream length) of wadeable streams at NEON aquatic sites. Raw survey data is collected with high-resolution total station survey equipment at each NEON wadeable stream site. Survey maps and channel metrics are produced and calculated using raw survey data (Level 0) that are geo-referenced to a global coordinate system (Level 4). Geomorphology surveys are conducted at each site once every five years or immediately following a storm event deemed to have significantly altered stream morphology within the aquatic reach. Geomorphology surveys conducted immediately after a stochastic event will assess event magnitude by quantifying changes in channel geometry, bed composition, and biological habitat. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.

Latency:
The expected time from data and/or sample collection in the field to data publication is as follows, for each of the data tables (in days) in the downloaded data package. See the Data Product User Guide for more information.
