Abstract

Aim of the study about water erosion and surface runoff on light chestnut soils is the development of an agro-landscape map in a scale of 1:25.000 on the basis of natural units and natural boundaries by using GIS combining digital and field data in the study area of the foothills of the Hi Alatau, located in the administrative district of Zhambyl and Karasay / Kasakhstan. The study includes the erosive processes determined by snowmelt and rain depending on slopes (on the southern and northern slope exposition). We determined the magnitude level of the runoff coefficient, the rate of soil erosion (in t/ha) and include a specialized GIS assessment of the study area to map the rate. The results also differentiate the water erosion resistance of the soils.
