RECLAMATION MEASURES FOR GULLY EROSION SITES A CASE STUDY OF OBOLLO-ETITI, UDENU LOCAL GOVERNMENT AREA, ENUGU STATE

Thesis Overview

INTRODUCTION
1.1 Background of the Study
Disaster have been defined and categorized in diverse by various scholars see for instance, Bates (2002). Hugo (2009), Naik (2009) and Keane (2004). Disaster which may occur from natural or man-made processes often involve large scale alternations of the areas they occurs and suffering of a sizeable number of persons. Human responses to disaster vary according to the nature of the disaster.
Advances in science and technology have aided the human race to stop the events, to predict the events and more out of the ways such disasters or discover ways of recovery after the events had taken place. However, some notable disaster which when they occur, death and loss of property usually result include, gas escapes earthquake, chemical spill oil, oil spills, forest fires, coastal floods generally etc. landslide, causes of loss property death and population displacement when they occur in densely-settled area of the world s within Nigeria landslides occur as follows ups from deep gully incision (Mozie 2010). The most devastating gully erosion in Nigeria are found in South Easter Nigeria in the populated Enugu, Abia, Imo and Anambra State and other lesser area is in Auchi in Edo State of Nigeria.
This project discusses the gully erosion control in Udenu Local Government Area of Enugu State, Nigeria.
1.2 Objectives of the Study
To determine the cause of the gully erosion in the Obollo-Etiti, Udenu L.G.A. gully site.
To construct maintain and unrest in the study are unfrustural works like roads, water schemes and gradual transfer of these to benefiting communities to engage in other activities that will increase agricultural production in the soil.
To design appropriate soil erosion control structures for gully erosion site.
1.3 Justification of the Study
The justification of this project work is seen in the aftermath of the gully development, which includes the destruction of the profile and the topography of the area, thereby hindering development around it. The downstream sedimentation is causing damage to the vegetation of area and a kind of sediment transfer to discharge outlet (which may cause pollution) is being seen effected by the overland flow that originates from the watershed. All these problems will be tackled when this work is successfully completed. The justification of this project work is also seen in the earnestness of the control. This is because the cost of reclamation and control is increasing on daily basis due to the continuous deepening of the gully by run off action and detachment by rain drop action.
