THE IMPERATIVE OF EXPLORATION AND EXPLOITATION OF VEGETATIVE COVER AND OTHER EARTH MATERIALS FOR GULLY EROSION CONTROL IN IMO STATE.
Publication Date : 15/03/2018
Gully erosion is a major environmental problem prevalent in Imo State. This trend is attributed to mostly the friable and unconsolidated soil which manifests a preponderance of coarse to fine sand with little or no fines or binding matrix. These gullies occur when surface water runoff and overland flow remove the soil along drainage lines, a process that has often created huge ecological problems which affects the physical, social and economic life of the affected people (Sheng, 1981) and Imo State is no exception. Despite studies by researchers in Civil Engineering including the Government on ways of combating this problem, the menace appears intractable as more and more sites keep developing from the same catchment area as the old ones being addressed both in spacial scope, severity and magnitude. The focal concern of this paper is to reevaluate existing and available approaches to gully erosion control in Imo State with a view to urgently provoking and facilitating further assessment of the problem as well as provide technical direction in our control and management strategies within our peculiar environment and ecological zones.
