***General Introduction***
This dataset contains the accelerometer log recorded during slope failure 
experiments in the Heerlen sand quarry in Netherlands, 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 in 2018.

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 the acceleration log is to support the Material Point Method numerical model 
validation in the Anura3D software against field data.

***Test equipment***
The accelerometer was a prototype Lagrangian sensor custom made for the experiment by 'Dr.Berges'
for Sibelco that manages the quarry. The sensor, previously calibrated in laboratory, was here
deployed for the first time in the field, in preparation of the flowslide experiment described in
chapter 6 of the PhD thesis: 'Sand slope failures: experimental and numerical advance'. The
results of this first experience have been reported in chapter 5.

***Description of the data in this data set***
The 'readings_Test01.xlsx' report the interpreted data from the raw data contained in 
'slopefailure.dat' . There are 2 additional 'review versions' in order to track the changes during 
data elaborations. The quote for the custom made sensor with technical specifications and costs is 
reported in the attached pdf file.
