Development of a GIS simulation model and the use of remote sensing for monitoring and prediction of soil salinity and waterlogging in the Nile delta (Egypt)

摘要

This paper is presenting the results of a three year program of the Belgian Ministry for Science Policy dealing with land degradation and remote sensing. In arid and semi-arid climates the soil salinity problem is becoming more and more important. In this paper two types of simulation models are presented, allowing the prediction of future risks for soil salinity and the interconnected problem of water logging. The method was elaborated in Egypt. One model is dealing with the delta soils, the other one with the desert soils in the newly reclaimed areas.
