metadata.name: dc.description.abstract
metadata.value: In this paper, we present results of interpretation of self-potential (SP) signals produced by a
  pumping test experiment of a heterogeneous aquifer. Heterogeneity is represented by a zone
  with low and high hydraulic conductivity in two types of configuration: planned boundary
  and strip-layer. We studied five models for each type of heterogeneity with two variants of
  hydraulic conductivity. We carried out three-dimensional modelling with the use of Modflow
  (for hydraulic heads and electrical potentials) and ElSources (for current source term). The
  SP distributions obtained from the pumping test indicate heterogeneity. We calculated the
  values of the anomalous field for a detailed study of the heterogeneities. We found a correlation
  between SP and drawdown for the case of heterogeneity with low hydraulic conductivity.
  We defined both boundaries of the strip clearly for the zone with low hydraulic conductivity.
  The outer boundary of the strip-layer was not fixed due to the high hydraulic conductivity of
  the heterogeneity and low hydraulic gradient at the boundary. We estimated dependence of
  horizontal thickness of heterogeneity on SP distribution. The results can serve as a base for
  defining the heterogeneities in the aquifer.
