Abstract

The Agalu-Nanka gully complex is located in Anambra State, Nigeria. Earlier studies attributed the genesis and growth of gullies to human activities and geomorphological processes. This study shows that the causes of the gully genesis and growth strongly lie in the hydrogeological and geotechnical properties of a complex aquifer system. These properties are related to the high hydrostatic pressures in aquifers that reduce the effective stress of inconsolidated coarse sands, thereby leading to erosion.
