Abstract:

Geotechnical characterization of gully erosion affected soils in Owerri, Imo State, Nigeria was carried out. Soil samples were collected from two locations impacted by gully erosion at varying depths of 0-15cm, 15-30cm and >30cm using soil auger. The same depths were maintained in sampling the non-gully impacted area (control). Geotechnical properties such as permeability, bulk and dry densities, Atterberg limits, compaction, shear strength and grain size were determined using standard procedures prescribed by ASTM D3418-05. The results showed that all the samples were non-plastic. Permeability values ranged from 4.0x10-2 to 3.8x10-3cm/s in the gully affected areas, and from 2.5 x 10-2 to 1.0 x 10-3cm/s in the control location. Similarly, the bulk density of the eroded areas was from 1.76 to 1.81g/cm3 while the control were from 1.48 to 1.62g/cm3. The shear strength at a constant maximum normal stress of 177.8KN/m2 varied from 78.5 to 86.9 KN/m2 at the gullied areas, while the control values were from 87.9 to 89.9 KN/m2. The values of all the parameters increased with depth.
