Soil erodibility mapping and its correlation with soil properties of Oued El Makhazine watershed,Morocco

Soil erosion is a result of many factors,such as rainfall intensity,steepness of slope,length of slope,vegetation cover,and management practices. besides all this,the inherent properties of a soil influence the ability of water to detach and transport soil particles. this intrinsic property is classified as soil erodibility. soil erodibility factor (k) from the universal soil loss equation (usle) was used in this study to estimate the value of soil erodibility of oued el makhazine watershed. in fact,k factor is affected by soil primary particles,organic matter content,soil permeability and soil structure. in this study,the samples of surface soil were collected from oued el makhazine watershed and then analyzed in the laboratory. using the k factor formula,soil erodibility was calculated for each soil sample. geographical information system (gis) tools were used to represent the spatial representation of the soil erodibility in the study area. © 2017,university of mohammed premier oujda morocco.
