ABSTRACT
Erosion is defined as the actual removal of the surface soil
which contains vital plant nutrients by wind, water and other associated
agents. Erosion has been a pressing issue in Nigeria today. Abia state, a state
in the south east is among the state that is badly affected by erosion. This
project work identifies Oroni in Abiriba, Ohafia L.G.A., of Abia state as an
area that is badly affect by gully erosion, the work also identifies the cause
of the gully ersion at Oroni as poor channel construction at the site which
makes the discharge from upstream to flow in another direction thereby creating
a parallel channel instead of the installed channels. A new design of soil
erosion control system for Oroni, Abiriba, Ohafia L.G.A., was carried out, also
various field and laboratory tests were carried out which include particle size
analysis, atterberg limits, specific gravity, moisture content, etc. A
trapezoidal channel was designed to carry 2.5m3/swith bottom width of O.8m,
depth of O.4m and bed slope of 3.16% respectively to control the erosion by
conveying the runoff to the Oroni river which serves as the outlet discharge
point, when this measures are properly implemented, the erosion occurring at
the study site should have been effectively controlled.
