Iraq is one of the Arabian area countries, which considered from the drier areas
on the earth, though it has two main rivers that pass through(Tigris and Euphrates);
it suffers the same problem as them (drought), only the rivers' nearby regions make
use of their water for (domestic, agricultural, and industrial purposes(.
One of the usable solutions is to utilize the groundwater (especially in the desert
regions). Using the Remote Sensing and geographic information system is a rapid
and coast effective techniques, they provide information of large and inaccessible
area within short span for assessing, monitoring, and management of groundwater
resources. In this study, an adaptive algorithm based on Canny edge detector noise
reduction idea and directional filters scheme submitted for lineaments automatically
extraction from LandSat7 (Enhanced Thematic Mapper Plus) ETM+ band 7 data
considering the lineaments spatial and spectral characteristics, yet the algorithm
validation examined using ancillary data of the same interest (Iraq tectonic map and
90m SRTM DEM). The analysis process achieved using Arc GIS 9.3 to recognize
the potential groundwater renewal and/ or accumulative zones in the selected arid to
semi-arid area (AL-Dibdibba formation basin).
