Changes of topographic profile in dried valley bottom

In the present paper, on the basis of altitude measurements, changes of topographic profiles of a chosen dried valley in Elizowkaon the arable land were presented. Intensity of water erosion was also studied on the unprotected loess terrain for 40 years.On the average, 22 cm of mud deposited on the tested section of the valley bottom (total area of 1.28 ha) along 500 m of the water race line, with the average width of 25.ʹ6 m. In consequence, the local erosion basis was raised and the average inclination decreased slightly. Physico-chemical properties did not significantly change within 40 years and these factors are typical of deluvial soils with unshaped profile. Their partial improvement points to reduction and stabilisation of erosion processes. That phenomenon is associated with slight thaw water run-off and the lack of larger storm precipitation.
