1. INTRODUCTION
Nowadays one of the major problems on global scale is the
rapidly increasing demand to the food. This demand is of course
totally parallel to the population growth. Even more land is used
for agricultural purposes day by day. Cultivation without using
specific control techniques, unplanned land use, such as
establishing industrial facilities or constructing summer houses
on the agriculture land, uncontrolled urban development and
also destroying forests are fundamental factors of soil erosion
(Biard and Baret,1997).
Soil erosion over Earth is a quite-frequent and well-distributed
problem. Mapping the level of risk of areas subjected to rain
and wind erosion is therefore all important issue. Models of soil
erosion highlight the importance of soil coverage by active
green vegetation and residue. When soils are covered by
senescing vegetation or crop residue, the cover fraction is often
very low and may coincide with heavy rainfall events. It has
been demonstrated that a 15% cover fraction by corn residue
reduces soil run off by 75% (Melesse and Jordan,2002).
In this study, the size of the amount of soil loss because of the
erosion in the surrounding area of the Ganos Mountain over
Thrace Peninsula region in Turkey was investigated by using
satellite data. Morgan method is applied to solve the modelling
problem of the soil erosion. The question why Morgan method
is preferred can be answered by the following explanations
made by geologists and agricultural engineers. According to
them Morgan method has a more powerful physical
fundamental than the USLE method and is easier and more
flexible method than the CREAMS method.
