Abstract

The study area is located at the 38°, 42' to 38°, 52' northern latitude and 45°, 23' to 45°, 40˝ eastern longitude with an area of 283 km2 and 8.5 km far from Republic of Azarbaijan. Large extension of unconsolidated and semi-resistant formation contain clay and salty alluvials, gypseous, marl, Clay plains, as well vast superficial mainly tiny formation at the low gradient intermountain points, have created background for genesis and development typical gullies. In the study area, GULLY EROSION not only caused the soil and vegetation destruction, but also created some problems for using agricultural machines. Thus, significance of this study becomes more clear. The results of climatic estimated indices_ such as Ws (the amount of wet in the soil), hydrothermal coefficient and some equations verified potentiality of the zone for gullyfication. Related to increasing of gradient caused decreasing of the superficial UNSTABLE FORMATIONS and then length and as well as number of gully. This subject estimated with linear regression for 43% samples in the area. There are negative significance with%95confidence between gullies length and their heights locations and %45 CORRELATION COEFFICIENT. Thus, with increasing of height, steepness become intense but diameter of destructed fine aggregate and soil materials decreased so, deep and large gully in compared with low steep surfaces, less formed. In the other hand the exist of reverse significant with %40 CORRELATION COEFFICIENT for gradient and depth verifies the above subject, (average deep of gullies at the plains is about 2.2m and in mountain area 1.62m). According to the results of this cause study, GULLY EROSION is one of the important factors to instability and destruction of superficial formations on the slopes and some Parts of plain area.
