Investigation of the ravine intensity with the modern geoderic methods under the arid climatic condition

It is established that the ravine erosion involves the whole area of the investigated territory. Destruction is 2,0-7,0 and more than km/?km?^2 on an area of 68,3%. The ravine height and density reach 15,6 pieces/?km?^2 in some places the mean-yearly growth of the ravines forms 0,34-7,48 m for length, 0.20-2.48 m for width, 0,10-1,16 m for depth. The ravine water-collecting area affects the development intensity. From 79 ravine systems having a little water-collecting area-from 0,02 to 0,47 ?km?^2, destruction in the 4th degree is less than 1,0 km/?km?^2, but in 36 ravine systems-from 5,0 to 7,5 km/?km?^2, in 12th - from 7,5 to 10,0 km/?km?^2, in 4th - from 10,0 to 15,0, but in the 1st of the ravine system-more than 15 km/?km?^2. A destruction rate of the separate ravine systems isn’t found depending on their water-collecting area that is connected with the conditions of their Location.
