MOLANO, C.E., SALAMANCA, M. and OVERMEEREN, R.A. VAN 1990. Numerical modelling of standard and continuous vertical electrical soundings. Geophysical Prospecting 38, 705-71 8.Analytical solutions of vertical electrical soundings (VES) have mostly been applied to groundwater exploration and monitoring groundwater quality on terrains of fairly simple geology and geomorphology on which the electrode arrays are symmetrical (e.g. Schlumberger or Wenner configurations). The sounding interpretation assumes flat topography and horizontally stratified layers. Any deviations from these simple situations may be impossible to interpret analytically. The recently developed GEA-58 geoelectrical instrument can make continuous soundings along a profile with any colinear electrode configuration. This paper describes the use of finite-difference and finite-element methods to model complex earth resistivity distributions in 2D, in order to calculate apparent resistivity responses to any colinear current electrode distribution in terrains in which the earth resistivities do not vary along the strike. The numerical model results for simple situations are compared with the analytical solutions. In addition, a pseudo-depth section of apparent resistivities measured in the field with the GEA-58 is compared with the numerical solution of a real complex resistivity distribution along a cross-section. The model results show excellent agreement with the corresponding analytical and experimental data.

Las mujeres rurales son agentes clave para conseguir los cambios sociales, culturales, ambientales y económicos necesarios para el desarrollo de un territorio; enfrentando retos de acceso limitado a créditos, salud y educación. Esto se ve agravado además por las crisis actuales a nivel sanitario y el cambio climático. Su empoderamiento no solo es fundamental para el bienestar de las personas, familias y comunidades rurales, sino también para la productividad económica de la región.
