Experimental data for 'Scaling laws for coastal overwash morphology'

This dataset contains the experimental data described in Lazarus, ED (2016) Scaling laws for coastal overwash morphology, Geophysical Research Letters, 43, 12113–12119, https://doi.org/10.1002/2016GL071213.

The physical experiments that produced these data were conducted at St Anthony Falls Laboratory (University of Minnesota, USA) in December 2014. The experiments were conducted in a 3 x 5 x 0.6 m tank filled with well-sorted coarse river sand. The tank and the experimental trials are detailed in Text S1 of the Supporting Information for Lazarus (2016): https://agupubs.onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1002%2F2016GL071213&file=grl55284-sup-0001-SI.pdf

This dataset consists of two *.csv files:

• '...THROATS.csv' – morphometric data for erosional (throat) features in the experimental barrier
• '...WASHOVER.csv' – morphometric data for depositional (washover) features on the back-barrier floodplain

Both files have the same general column headings: feature width (in the alongshore dimension) [m], feature length (in the cross-shore dimension) [m], feature area [m²], feature volume [m³], alongshore spacing (centroid-to-centroid distance to neighbouring feature) [m], and real alongshore position [m].

All features were formed along an initially geometrically uniform (topographically homogenous) trapezoidal barrier under inundation-type forcing (denoted in 'forcing' column). These data report the compiled results of three experimental trials (denoted in 'trial' column).

Note that these data are also available as part of the Supporting Information for Lazarus (2016), but the format in which they were originally uploaded is not conducive to straightforward integration into open-source analysis. Publishing them here, in this tidier format, is an effort to rectify that.
