Cím:Wind and sheet erosion investigations in sample areas in the Nyírség / Tóth Csaba Albert, Négyesi Gábor, Lóki József, Szabó Gergely, Buró Botond
Megjegyzések:We carried out wind erosion measurements in the field on three sample areas in Nyírség region, and in wind tunnel. During examinations we measured the erosion and accumulation of soil and studied the process, spatial and time pattern of wind and sheet erosion in areas in various geomorphological settings cultivated intensely with different topsoil conditions and with different commercial plant cultures. The surface changes measured in the field measurements verified the fact, that the rate of surface transformation is bigger on bare plough-land, than surfaces are covered by vegetation. The mechanical composition of soils played important role: where soil crust was forming out on the surface, the amount of eroded material was smaller. Erodibility data obtained from wind-tunnel measurements are in accordance with those measured in the field surveys, i.e. the 2-2.5 cm of material loss measured in laboratory were supported by the field measurements. In wetter periods linear and areal erosion of flowing precipitation water had major role in shaping sand surfaces. The performed sheet erosion studies yielded more-or-less similar material loss values, i.e. 0.5-1 cm of material is denuded annually on average from the cultivated wind-blown sand surfaces.
