metadata.name: dc.description.abstract
metadata.value: We carried out a numerical analysis of Self-Potential (SP) signals produced in the course of
  pumping test experiments. We studied SP responses on the basis of the GWFGEM code. In the
  models, the pumping well partially penetrated the aquifer. We considered the short well filters
  (1/5 of the aquifer thickness) and longer filters penetrated up to 4/5 of the aquifer thickness.
  Numerical modelling results revealed an increased sensitivity of the SP signals to the length and
  the depth of the pumping well filter compared to the drawdown. The pumping well casing and
  screen material (electrically conducting, metallic vs. electrically insulated, PVC) determines
  SP distributions on the ground surface. For the insulating casing, the sensitivity of SP signals
  to the drawdown variation is small. In contrast, SP distribution on the ground surface for the
  conducting case is closely related to the drawdown distribution and can serve as a proxy for the
  drawdown. For a reference model of the water pumping well, the relationship between SP and
  drawdown is linear. In the case of short screens, this relationship is logarithmic. Time variations
  of SP show similar patterns for all studied models for both insulating and metallic casings; only
  the magnitude of variations was found to be different. These results should be considered in the
  modelling and interpretation of SP data obtained in pumping test experiments.
