Abstract:The study involved an integration of field observations, geotechnical analysis, slope stability analysis, gully expansion rate analysis and determination of the soil erodibility factor (K). Fifteen representative gullies were studied extensively. The Grain size distribution analysis revealed that the soils are composed of gravel (5.77–17.67% and 7.01–13.65%), sand (79.90-91.01% and 82.47–88.67%), and fines (2.36–4.05% and 3.78–5.02%) for Nnewi and Nnobi respectively. The cohesion and internal friction angle va… Show more
