Abstract EN

The area of study is within Al-Jazeera region which is located within the administrative boarders of Al-Anbar governorate in Iraq.

It occupies (362km2).

In this area ecological formations have been found out which their age belongs to the lower Myosin age in the tripartite era and Holocene age in the quadripartite era .The precipitations of the tripartite era formed the Euphrates River, Fatha and the Enjana, while those of the quadripartite era included the precipitations of the river gradations, the precipitations of the desert swamps and the gypsum shell.

The surface of the area of study consists of a few relief plot of land which gradually descends from the north and western north towards the south and eastern south directions.

The formation and development of most of the earth forms relates to the ancient climate nature of the region as the current dry climate, namely the windy type, is unable to form some earth form .

The soil type of this region is low to moderate salty one and its organic value is low.

Its textures are of middle to moderate roughness, while the percentage of the sand, silt and clay is vertically and horizontally different.

The littleness of plant cover and the differences in some of the natural plant descriptions are apparently appear .

Hence, and according to the above mentioned data, the land appearance has been classified as has different shapes in this region within 6 land units which includes the constructional shapes, erosion shapes and aquatic and windy precipitations.
