دراسة الترب المتأثرة بمياه المصب العام بالاستعانة بتقنيات الاستشعار عن بعد

الملخص EN

Provide massive amount of main out fall water with salinity increased little or a lot comparied to the permissible limits for Agriculture.

this requires finding techniques by which using this water with less possible deterioration,on chemical Topographical maps and heterogeneity reports was used as a reference information to help in the processes of interpretation.

The values NDVI for years (2006, 2009, 2011) Satellite image (visual) was linked with the value of electrical conductivity.

This will contributed to illustrate the effect of Salts (electrical conductivity values) on the values of NDVI, and then to reflectivity (soil-water-plant).

The result of the study indicated:- that the year 2009 Show an increase in green areas and this due to the availability of water and increase the proportion of cultivated land compared with then the years (2006, 2009, 2011).

- Correlation between the value of the EC and NDVI for the year 2011 at which satellite image taken approximately at soil sampling time.

- The possibility of using GIS and R.S in the diagnosis of lands covering depending on the behavior of each type of spectroscopy for each cover (soil- water-plant).
