ASFAHANI, Jamal. New Semi-Quantitative Approach for Interpreting Vertical Electrical Sounding (VES) Measurements - Using a Fractal Modeling Technique, Case Study from Khanasser Valley, Northern Syria. Geofís. Intl [online]. 2021, vol.60, n.3, pp.211-228.  Epub 31-Jan-2022. ISSN 2954-436X.  https://doi.org/10.22201/igeof.00167169p.2021.60.3.1920.

A new fractal modeling technique, adapting the concentration-number (C-N) model and the threshold break points concept is proposed to interpret vertical electrical sounding (VES) measurements distributed along a given profile. A new semi-quantitative approach is consequently proposed to readily differentiate between different apparent resistivity populations, where two-dimensional (2D) semi-quantitative interpretation and a preliminary geological analysis could be constructed. The new technique is applied and tested on a case study from the Khanasser Valley region, Northern Syria, where different selected profiles (LP1, LP2, LP3, and TP5) are interpreted. The suitability and feasibility of the proposed approach are confirmed and approved through different comparisons between the multi-fractal established cross-sections and the traditional one-dimensional (1D) VES interpretation models. It is recommended to routinely use this new proposed fractal approach in geoelectrical research for interpreting VES measurements distributed along a given profile.
