***General Introduction***
This dataset contains the timelapse video recorded 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 video was recorded by a timelapse camera installed in a location nearby the intended
experimental site. It was recorded on the 28th of May 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 Brinno Camera was set to record a picture frame of the dredging site every 15s. 

***Description of the data in this data set***
Two slides were triggered in sequence for the experiment: 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.

This video shows field activities and the moments in which the first slide was triggered 
and the movements of the dredging vessel to sustain the failure until the backscarp reaches 
the instrumented trench at the top of the sand slope.
