Abstract
Globally, soil erosion menace has been a major problem threatening man’s environment, the consequent effect had been degrading the environment, making it unfit for agricultural production and sustenance of infrastructure. In view of this teething problem, the soil erosion menace at Uwani–Amokwe community was critically examined and assessed, the renaissance survey revealed developed and developing gullies, linear incisions, impassable roads, poor drainages, poor agricultural produce, harvests etc. A mechanical analysis of soil composition revealed sandy loam soil which naturally does not support adequate vegetation; the erosivity index as determined from meteorological data is 75.84mm/hr and orchestrated 0.06m/s discharge; the cone-penetrometer test indicated liquid limit of 24% beyond which working the soil will be damaged; the reduced levels/ elevation indicated gentle slope towards the gully heads for the worsened selected gully units and adequate capacity trapezoidal channel and culverts were designed to handle the discharge.
