Data from: Threshold Behavior of Catchments with Duplex Hillslope Soils Feeding Soil Pipe Networks

Soil pipes are large soil pores that are generally parallel to the hillslope surface and are created by internal erosion of a pore due by rapid water flow. The internal erosion of the soil pipe can result in collapse of the soil pipe which produces surface expressions such as flute holes (small vertical opening connected to the soil pipe), sinkholes (closed depressions), and gullies. Soil pipes tend to form in soil with a water-restricting sublayer, i.e. duplex soils, that foster the development of perched water tables on hillslopes and thus lateral flows. This dataset corresponds with two published studies conducted on loess covered catchments in northern Mississippi, USA within the Goodwin Creek Experimental Watershed that contain extensive networks of soil pipes and corresponding collapse features. These loess soils contain fragipan layers that were found to perch water, thereby initiating the piping processes. The dataset contains data from two papers, specifically these include: (i) the spatial distribution of soil pipe collapses and their size measurements from the Wilson et al. (2015) paper, and (ii) hydrologic measurements of perched water tables on hillslopes, water levels of selected soil pipe locations, and precipitation from the Wilson et al. (2017) paper.
