Mean Rate of Gully Head Advancement in Edo State, Nigeria

Abstract

A B S T R A C TThe issue of gully erosion is of major concern in Nigeria. The study was carried out in Edo state, Southern Nigeria. Edo State was chosen as the study area due to the fact that the magnitude of gully erosion has resulted in the loss of lives and properties, destruction of arable lands and wastage of large areas of usable land. In this study, an effort was made to identify the major gully sites in the area and determined the mean rate of gully head advancement. The result revealed that gullies in Edo North had mean rate of head advancement of 80.30 meters per a year, Edo South 52.03 meters per a year and Edo Central is 17.80 meters per year.
