In this
study, it is aimed to determine the potential erosion risk condition of the
area using remote sensing techniques and RUSLE method in Halfalı Stream
Watershed, which is 25 km away from Kahramanmaras province. With the purpose of
applying this method, rainfall erosivitiy index (R) has been generated by means
of modified fournier index (MFI).Soil erodibility factor (K) has been produced
using Inverse Distance Weighted technique and soil sample obtained from study
area. Slope length and slope steepness factor (LS) has been created by the help
of digital terrain elevation model. Vegetation management factor (C) has been
generated using remote sensing techniques. Whole factors obtained have been
overlapped in Geographic Information System (GIS) and soil loss belonging to
study area has been determined using raster calculator command within map
algebra module. It has been divided into 5 classes and erosion risk map has
been produced. According to potential erosion risk map obtained, 60.35 % of area has been subject to very low
erosion risk, while 2.60%, 6.08%, 10.37% and 20.60% has been subject to low, medium, high
and very high erosion risk, respectively.
