1.0INTRODUCTION
1.1Background of the Study
Soil is
the naturally occurring, unconsolidated or loose covering or broken rock
particles and decaying organic matter on the surface of the earth,
capable of supporting life. Soil is also known as earth; it is the
substance from which our planet takes its name. it consists of sand,
clay, sit and organic matters. The important of foil is too many to
mention. For instance, the life we are living today depend on soil. Soil
is a critical component in the mining and construction industries. Soil
serves as a foundation for most construction projects. Massive volumes
of soil can be involved in surface mining, road construction, and
construction of other structures. Soil is critical to the environment,
as well as food and fiber production. Soil provides plants with minerals
and water. Soil absorbs rainwater and releases through evaporation
preventing and controlling both flood and drought respectively. Soil is
also the natural dwelling place for earth micro and macro organisms.
Also houses water for mans use.
Today, one of the most serious
environmental problems facing our nation and the world on general is the
loss of top soil layer through the process of detachment and
transportation caused by the impact of raindrop and the resulting
overland flow. Soil erosion is the process by which the surface of the
land is attacked, resulting to gullies, in valleys, cliffs and hills and
it is completely washed into water bodies. It is composed of many
factors the most basic if it is the soils and rainfall factors which is a
function of intensity, duration, infiltration, susceptibility including
soil detachability and transportability.

ABSRACT - [ Total Page(s): 1 ]Soil loss is as a result of detachment and transportation of soil particles from one place to another due to rainfall. The rate of soil erosion has been of great concern to the government and people of Imo state as regards to farm land and environmental degradation. This work analyzed the soil samples collected from two erosion sites namely, nNkede and Akaokwa all in Imo State and the soil loss for the samples which is the mainstay of this project was determined using a rainfall simulator. It wa ... Continue reading---
