Topography data:

Files: Topography_Exp_1; Topography_Exp_2; Topography_Exp_3
All topography data have been taken by hand, every ten centimetres in length and width, with a ruler. All data are given in cm.
The area covered are 3, 5.94 and 4.86 mē respectively for the three experiments realized.
X represents the location in length.
Y represents the location in width.
Z represents the location in height. 
Later, data have been treated by ArcGIS (version 10.6.1).

Data particles used:
File: Data_particles
We used a mixture of plastic particles with a ratio 7:3 of coarse and thin material. Melamine TT60-80 and TT100-200 are from Sansho Kenmazai company. 
Also, we used siliclastic sand of different colours, to have a better view of the morphology created. 


Location of measurements:

This Excel file (Location_data_velocity) is used to see where the samples have been taken for all the runs of the three experiments.
Locations of concentration measurements and flow velocity measurements are indicated. 
Samples of concentration have been taken by a siphon, and an acoustic Doppler current profiler (ADCP), manufactured by Nortek Inc. (Vectrino Profiler) from Norway, was used to measure the vertical profile of the flow velocity.

Flow velocity:

Files: VectrinoData.100.19.Vectrino-II.00000, VectrinoData.107.19.Vectrino-II.00001, VectrinoData.113.19.Vectrino-II.00000, VectrinoData.136.19.Vectrino-II.00000, VectrinoData.142.19.Vectrino-II.00001, VectrinoData.155.19.Vectrino-II.00001, VectrinoData.155.19.Vectrino-II.00002_1, VectrinoData.155.19.Vectrino-II.00002_2

These files are raw data of flow velocity. 
To read them, we used the six scripts joined (names of the files: adjustHeightVelData.m, bottom_filter.m, calc_ustar.m, findRotationVelData.m, readVelData.m, VecProfil.m), to obtain the shear velocity u* (m.s-1). 

Concentration data:

File: Concentration_data
To take samples of concentration of the flow we used a siphon with 10 tubes placed every 1 cm vertically. The samples arrived in beakers, that we weighed on a scale. After that, we waited that sediment felt at the bottom of the beaker to take out all the water and salt, and we put them in a dryer, to evaporate the remaining water. Finally, we weighed them again to have the weight of sediment only. Then, we obtained the concentration in w/w% (weight percentage), and v/v% (volume percentage). 

Granulometry flow:
File: Granulo_flow
To have the granulometry of the flow, we used the samples of the flow we obtained by the siphon, after dried them. After, the granulometry analysis has been done by a settling tube grain size analyser (Naruse, 2005) and were subsequently processed using STube software (version 1.0).
