Abstract Assessment of land degradation indicators based on integration of Remote Sensing (RS) and Geographic Information Systems (GIS). Global Assessment of Human-induced Soil Degradation (GLASOD) is necessary to monitoring the land degradation extent and to control its impact. There is a wide range of deltaic forms around the world, but all are the result of interaction between fluvial and marine processes in different coastal environmental settings, such as Nile delta in Egypt and Niger delta in Nigeria. Two of TM/OLI-TIRs images represented the study areas were used to assess the land degradation types in the two deltas. The current study focused on the geofeatures of the studied areas and the assessment of Land degradation types were dominant in the studied area. In the present study, two approaches were employed to accomplish this objective. One of them depended on the characteristics of soil profile as a whole, while the other was based on the geostatistical analysis of the surface layer of the soil profile. The main obtained results from carrying out the current study revealed that the dominated lithology unit was floodplain deposits which constituted more than 84.5% of the total studied area in Nile Delta subset; the moderate basin covered 525.80 km2 which represented 33.29 % of the total area; thus it was considered the highest percentage of the total area |
