الملخص EN

Rills and gullies in El-Quss Abu Said Plateau were formed due to the ancient rains whose geomorphological effects are still evident there.

After the Eocene sedimentation of Tertiary period, a tectonic movement accompanied by Syrian arcs movement hit the Plateau and caused a convex-like torsion that has made its surface higher than the surrounding area and its axis northern/eastern-southern/western.

A number of multi-directional refractions also changed its structure, and its limy formation affected its topographic nature in such that its surface has become rather flat with slopes in the four sides.

Rills on the top and gullies on the bottom have begun to emerge thus.

This is why rills in longitudinal and horizontal sectors are long, ramified, relatively sloping, and wide while they are hardly 1m deep.

Unlike rills that are linked with big basins, steep gullies are related to the Plateau bottom.

Their drainages in longitudinal and horizontal sectors are characteristically short, linear, highly sloping, and narrow, and they are always more than deep.
