Resumen:
Specific conditions of the studied area, where natural or anthropogenic obstacles do not allow carrying out conventional Electric Resistivity Tomography (ERT-3D) arrays, employing parallel transects. It is necessary to construct new ERT designs able to be adapted to any particular zone under investigation. 'L'- And 'Corner'-arrays were designed to surround the target to acquire reliable geophysical information from the subsurface. Combinations of these arrays employing more conventional settings (Wenner- Schlumberger, Dipole-Dipole, and so on), are applied to design alternative electrode geometries. The circle, the triangle and the horseshoe arrays are investigated to study the subsoil of different types of scenarios. The efficiency of such alternative arrays was verified on the examples considered. Such studied areas are: a pre-Hispanic circular pyramid, a seawater intrusion and a small urban neighborhood. Results are quite encouraging, where coverage at depth was adequately obtained, and inverted results computed were very interesting.
