Abstract

Introduction: Worldwide salinization and degradation of soil is a widespread and important environmental challenge. Soil salinization is one of the most common land degradation processes in arid and semi-arid regions, where evaporation exceeds over precipitation. Under arid climatic conditions, soluble salts are accumulated in the soil, influencing soil properties and environment with ultimate decline in soil productivity.Soil salinity monitoring in irrigated and drained fields is necessary to follow the control of soil salinity provided by a drainage system. A subsurface drainage system can prevent or decrease the salinization hazard Trend, a common phenomenon wherever irrigation is practiced under arid and semi-arid climatic conditions. About 77 million hectares of the world's land have been saline as a consequence of human activities (secondary salinization), with 58% in irrigated areas.20% of the world’s irrigated lands are affected by salt, but this condition increases to more than 30% in countries which are located in arid lands such as Egypt, Iran and many similar areas.Implementation of this assessment, before doing any action, needs to use adequate techniques and to record the changes and disclose of soil salinity ratio and domain. REMOTE SENSING data providing namely satellite image and Arial photos along with processed thematic maps from this images over GIS platform is most effective in both coast-speed and accurate to control and assessment of this phenomena.Data providing is one of the main challenges in case of soil salinity studies based on REMOTE SENSING techniques.In this case, data resolution in form of spectral, spatial and temporal is an important task for data selection and collected from source. In order to provide data for such studies many sensors can be nominated while the TM and ETM sensors carry by Land sat satellites as well as ASTER sensor are more popular which is many researches has been done so far...
