Sarygamesh basin one of the Bulhary Chay tributary take place in Moghan plain,northeastern Azarbyjan area in Iran and south edge of Kora- Araz zone. Aims ofthis research are study specificities and geomorphic evolution of Sarygameshbasin, survey rivers work on structure and geologic formation, and correspondinghydrographic with earth structure. Toward above aim is used to litologic, structuraldata, and water network data. The research method in this study are observer, filed,Descriptive and library method. Data and information of this research wasAssemblage by 1- topographic maps in order to Primary Identification andtopographic analysis,2- geology maps for recognition of rocks and formations andgeologic structure, 3-aerial photograph and satellite image for identifygeomorphologic landforms. Arc view and Arc GIS software used for drawingmaps. This basin was belonging to three different structural zones in the names ofcrumpled Allah Yarlo-Havai zone, volcanic plateau and Moghan sedimentarybasin. Internal processes are created anticlines and synclines with eastern- westerntrend. Process of external dynamic was impressed structural landforms and wascreated landform and different geomorphic phenomena. In some of area differenceresistance of rocks was created reverse roughness in the basin for example hangingsyncline. Misadjusting of river network with earth structure is chiefly antecedenceand crate cluse. Erosion in the different forms was changing mountain landscapeand changing forms of initial structural landforms. In the resent years atrophicerosion has justify important role in alteration of area landscape
