The research aims to uncover the variation of morphometric features of Wadi Mezal within the western plateau
in Najaf Governorate and the extent of the influence of natural geographical factors represented by the geological
situation and also the characteristics of the surface, climate, water resources, soil, and natural vegetation on the
variation of these characteristics, which showed that the basin reached maturity or balance in its cycle. The basin
occupies an area of 654 km2
, most of which is within the western plateau of the Najaf governorate, as the basin is
located within the stable, non-twisting pier at the division of Iraq physiographically. The research included an
introduction that comprises the problem, hypothesis, goal, importance, methodology, and spatial boundaries.
The first topic came to study the natural factors of the study area, while the second topic dealt with an analysis of
the most important morphometric characteristics of the basin and its water network using geographical information systems and a number of important programs and then the most important results were reached.
