Gully erosion is a natural disaster that have affected many parts of southeastern Nigeria particularly the state of Anambra. The causes of progressive gullies in some parts of Aguata local government area of Anambra state was investigated. The gullies can be found in Ula region of Ekwulobia, Otaalu region of Akpo, Ogbei region of Nkpologwu and Achina town. Some samples were collected from the walls of the gully at depths ranging from 1.5 to 2.5m. Laboratory analysis which include index property tests and compaction tests were carried out on the samples. Questionnaire survey and analysis was also carried out to sample people’s opinion. Unified soil classification system classified all the soil samples under clayey sands (SC) which is susceptible to erosion. The empirical values of erodibility factor, K determined show that the soil samples are moderately erodible. Based on the laboratory test results and questionnaire responses, it is evident that soil properties and human activities contribute to the development of gullies. It is recommended that all effort should be made to protect soils from exposure to runoff especially at slopes.
