This study aims to detect the changes that happen in Halabjah area and special in
Darbandikhan Lake. As well as the vegetation cover during 1990 to 2000. The
image data used in this study are Landsat 5TM (30-4-1990) and Landsat 7 ETM+
(28-6-2000) and it has been compared and inter- printed visually.two kinds of
techniques have been used in this study; image differencing and normalized
difference vegetation index (NDVI). Ground truth checking was done to detect the
changes that take place in the study area. The results gained from this study shows that the volume of the water has been
reduced for about (1558005800) cubic meter and the area of vegetation cover
reduced for about (39399.4) Hectare. This indicates great changes took place in the
study area. These changes are due to reduction of rain fall and the policy of water
balance
