Plot the Vertical Electrical Sounding data ohmic -area

Parameters

  • data (*) – contains the depth measurement AB from current electrodes, the potentials electrodes MN and the collected apparent resistivities.

  • search (*) – The depth in meters from which one expects to find a fracture zone outside of pollutions. Indeed, the search parameter is used to speculate about the expected groundwater in the fractured rocks under the average level of water inrush in a specific area. For instance in `Bagoue region`_ , the average depth of water inrush is around 45m. So the search can be specified via the water inrush average value.

  • pre_computed (bool, default=False,) – If True computed the ohmic_area parameters. If False, the ohmic area arguments must be passed to xy, xyf and xyarea, otherwise an errors will raise.

  • xy (array-like of shape (n_AB, 2)) – Arraylike of the sanitized depth measurement AB from current. electrodes n_AB. See vesDataOperator().

  • xyf (array-like of shape (n_fit_samples, 2)) – Array-like of the fitted samples i.e the number of points for fitting the sounding resistivity values from the surface thin the total depth. The fitted rhoa showns a smooth curves. The default point is 1000.

  • xyarea (array-like of shape (n_area, 2)) – Arraylike of the resistivity positions of the depth measurment AB where the fractured zone is found.

  • fbtw (bool, default=False,) – If True, filled the computed fractured zone using the parameters computed from xyf and xyarea.

  • kws (dict - Additionnal keywords arguments from Vertical Electrical Sounding data operations.) – See watex.utils.exmath.vesDataOperator() for futher details.

Notes

The first and second columns of xy, xyfit and xyarea are the position AB/2 and their corresponding resistivity values.
