A recent study published in African Scientific Reports combines electrical resistivity surveys, soil pH analysis, Sentinel-2 satellite imagery, and GIS modelling to assess soil corrosion susceptibility in Sabon Gida, Katsina State. Data from 44 vertical electrical sounding locations showed resistivity values ranging from 23.11 to 1779 ฮฉm, while soil pH ranged from 6.3 to 7.1. The integrated corrosion susceptibility map indicated that most of the area has moderate corrosion risk, although localized highly corrosive zones were identified. The findings suggest that Sabon Gida is generally suitable for buried metallic infrastructure, but site-specific investigations, direct corrosion measurements, protective coatings, cathodic protection, and routine monitoring are recommended before installation.
