Data for Quantification and classification of grainflow morphology on natural dunes

Overview:

The attached file, “GrainflowMorphologyCharacteristics.xlsx”, includes the grainflow morphometric attributes used in the article “Quantification and classification of grainflow morphology on natural dunes” by Zhang, Pei; Sherman, Douglas J.; Pelletier, Jon D.; Ellis, Jean T.; Farrell, Eugene J.; Li, Bailiang, published in Earth Surface Processes and Landforms.

Key to variables (unit):

Date: date of data collection at Jericoacoara, Brazil.

Dunes: “S” indicates samples from the smaller dune (21.3 m high), and “L” indicates samples from the larger dune (54.5 m high). Details of the metrics may be found in the associated publication (https://doi.org/10.1002/esp.5348).

\(\bar{l_{g}}\) (m): average length

\(\bar{w_{g}}\) (m): average width

\(r_{t}\) : rectangularity

\(TRI\): triangularity

\(e_{g}\): elongation

Type: classified types
