***General Introduction***
This dataset contains data collected during slope failure experiments in 
Blawue Kei sand quarry in Lommel, Belgium, as part of Bolognin Marco's PhD Thesis project.
It is being made public both to act as supplementary data for publications and the PhD
thesis of Bolognin Marco and in order for other researchers to use this data in their own
work.

The data in this data set was collected by a bathymetry scanner underwater 
and UAV above water, on May 31st 2019.
This research project was made possible by the NWO grant (13889) 
MPM-Flow Project: Understanding flow slides in flood defences

***Purpose of the test campaign***
The purpose of these experiments was to investigate and monitoring a flowslide event 
during sand mining activities. The resulting dataset was considered important to validate 
the Material Point Method numerical solution as implemented in the Anura3D software.

***Test equipment***
The point cloud was logged by a bathymetry scanner in use in the suction dredger vessel 
in use provided by Sibelco. The UAV was a DJI drone, also provided by Sibelco. Resulting
data were combined by using cloudcompare.

***Description of the data in this data set***
Two slides were triggered in sequence: the first one to prepare the slope, having a slope 
angle close to the critical angle. This required continuous excavation to remove the 
mobilized material. 

The second slide is let propagate undisturbed after triggering it.

The data describe the X,Y,Z coordinates of the sand slope after triggering the second slide.
