Abstract EN

The present study is being developed in a mountainous environment with a solid and rugged rocks located to the east of district of Akra.

The study area covers an area of 100 km.

This area, like many parts of Kurdistan in Iraq, suffers from environmental risks.

To reach the goal of the research is to understand the evolution of the environment in the study area and the extent of the dangers caused by weathering actions as well as the erosive factors.

The study of environmental hazards has been the subject of two folds: the first is the diagnostic side, where the researcher discusses the subject of the current terrain conditions together with the mechanical configuration of the reliefs and their exact locations of these features by elaborating a "Dynamic Geomorphological Map".

The second aspect of the research is represented by the decision taken by the researcher under the indicators of diagnosis and analysis of the first phase was done to bring the "Map of the environmental hazards" and included what is actually, De facto, threats to the environment of this region.

The field work resulted in the preparation of the first and the second maps of the region according to the symboles of the French Geomorphological School.

This discusion is un essay to understnd the mechanism of evolution this kind of montaignous region.

It present un preliminary step toward thorough regional planning.
