Mary, B., Peruzzo, L., Boaga, J., Schmutz, M., Wu, Y., Hubbard, S. S., and Cassiani, G.: Small scale characterization of vine plant root water uptake via 3D electrical resistivity tomography and Mise-à-la-Masse method, Hydrol. Earth Syst. Sci. Discuss., https://doi.org/10.5194/hess-2018-238, 2018.


For each of the Electrical Resistivity Tomography and Mise-à-la-Masse data sets, 4 files are provided. 
- File 1: raw ERT data
- File 2: raw MALM data  x2 (stem and control soil injection)
- File 3: a geometry file
- File 4: a mesh file

The naming convention is: 
PlantNb*_SequenceType*_ERTorMALM_(SoilORStem).*bin

For the synthetic case we provided: 
- The image of the shape of the anomaly
- The initial resistivities values assigned for each cells of the mesh
For the fwd simulation, use each nodes contained in the anomaly's cells as current sources

The electrical tomography data is given in .bin format and can be read using Prosys2 available from http://www.iris-instruments.com/download.html#processing or directly using the pyBERT (open source software) unified format  (http://www.resistivity.net/download/bert-tutorial.pdf).

The coordinates of the electrical sources and receivers coordinates are given in SI units (m) in the *.geom file as space separated ASCII files.

The mesh file (*.msh) was created (and can be read) using gmsh (version 3.0.6). This files is common for the inversion and modelling of all the datasets i.e. MALM, ERT and synthetic data.

For the geophysical figures in the publication, the following ERT files have been used:
Figure 4 and 5: Synthetic_Model_InitialRes.dat
Figure 6: Plant1_DipDip_ERT.bin
Figure 7,8 and 9: Plant1_PolePole_MALM_Stem.bin, Plant1_PolePole_MALM_Soil.bin
