Abstract

Sarygamesh basin one of the Bulhary Chay tributary take place in Moghan plain, northern Ardabil province and south edge of Kora- Arax zone. This basin was belonging to three different structural zones in the names of crumpled Allah Yarlo- Havai zone, volcanic plateau and Moghan sedimentary basin. Process of external dynamic was impressed structural landforms and was created landform and different geomorphic phenomena. In some of area difference resistance of rocks was created reverse roughness in the basin. Misadjusting of river network with earth structure is chiefly antecedance and crate cluse. Erosion in the different forms was changing mountain landscape and changing forms of initial structural landforms. In the resent years atrophic erosion has justify important roll in alteration of area landscape. In quantitative geomorphology of drainage basin studies, examination of some characteristics is consideration basis of studies; Horton named these characteristics "complexes of drainage network". Spies of research are topographic and geologic maps and geographic information system. Sarygamesh basin has 783 Km2 areas, 70 km long, 150 km perimeter, 0.3 form factor indexes, 1.5 compactness indexes or Gravelius index, 1.25 circular indexes and with 64.4 lengths and 12.6 width equivalent rectangles is an elongated basin. These characteristics were increased time of concentration of basin (7.4 hr). Longitudinal profile of River is concave and approximately even and Bifurcation ratio is4.7. Drainage compression is 0.3 km km2 that show low of drainage compaction; because of resistant and hard geologic formations, high of rocks infiltrations and wealthy of vegetable cover.
