| description | Over the past decades, water erosion has increased significantly in the Shyngyrlau River basin. Recreational development,
haphazard construction and operation of roads have led to increased water erosion and the formation of numerous linear erosion
forms. Erosion reduces the natural resource status of the region. Water erosion develops in most cases along roads laid along the
thalwegs of the ravine-hollow network. The light substrate along with sparse vegetation cover (the sparseness is aggravated by
intensive grazing) predetermine its rapid development. Water erosion is an acute problem arising from the present climate change,
agricultural intensification and diverse forms of anthropogenic land degradation. Assessment of present and potential soil erosion is
useful for landscape preservation as well as development planning. Multi-analytical modeling can provide a quantitative and
consistent estimation of soil erosion and sediment yield under locally specific environmental conditions. The soil loss model,
Revised Universal Soil Loss Equation (RUSLE), integrated with GIS, has been used to estimate soil loss in the Shyngyrlau Basin (a
left-bank tributary of the Ural River, NW Kazakhstan). The RUSLE model is based on remote sensing and field data; erosion
probabilities were determined using GIS. The percentage ratio of the soil loss in the Shyngyrlau River basin shows erosion variation
of 0.001–2.47 t/ha/yr. The degree of erosion increases with the length of the slope. A new factor Chip curvature (Cu factor),
defining the accuracy of the soil loss results, was defined. According to this factor, soil erosion in the study area is 0.007–2.48
t/ha/yr within the low erosion class. The lowest indicator of the K factor is 0.2 in sandy clay soils used as pasturelands. The
highest K factor (0.3) relates to clayey arable soils. The research results add to implementation of new strategies in soil
management and conservation practices reducing soil erosion in the Shyngyrlau Basin. Both climate and anthropogenic factors
are seen behind the activated ground erosion. The development of forms of water erosion leads to a violation of the integrity of
modern natural complexes of the West Kazakhstan region, which significantly reduces their stability and recreational potential. |
