Data supporting “Soil Crack Width Controls Preferential Flow Velocity Through Drag Partitioning”

This archive contains data that support the conclusions of the manuscript “Soil Crack Width Controls Preferential Flow Velocity Through Drag Partitioning.” Detailed information is provided in the .xlsx file.

Files 1.1 and 1.2 present the calibration results of the newly developed monitoring fiber-optic cable used in this study.

Files 2.1 and 2.2 present the temperature evolution data recorded by the monitoring fiber-optic cable before and after preferential flow flushing under both laboratory and field conditions.

Files 3.1 and 3.2 contain the monitoring results from the laboratory experiments used for preferential flow velocity quantification, including observations of the coupled evolution between crack width and preferential flow velocity.

Files 4.1 and 4.2 present the monitoring results from the field experiments, showing the coupled evolution between preferential flow velocity and crack width.

File 5 presents the vertical profile data of soil cracks extracted from the three-dimensional photogrammetric reconstruction results.
