Title of the thesis:Wind erosion intensity assessment using mathematical modeling
Summary:Wind erosion detach soil surface by mechanical power of the wind (abrasion), transport soil particles (deflation), and deposit loose top soil in other place (accumulation). Wind erosion does not affect large soil loss as widespread water erosion but its effect in some parts of our land is evident. For erosion control measures it is necessary to determine so-called acceptable (tolerated, limit) value of soil intensity (erosion). While according to Act No. 220/2004 on Protection and Use of Agricultural Land in the Slovak Republic were acceptable soil loss determine to 40 t.ha-1.y-1, in from 1st April 2013 acceptable value 15 t.ha-1.y-1. We determine erosion intensity with equations WEQ, RWEQ and with direct measurements of wind erosion with soil particles catcher BSNE. Models have been applied to four model areas, cadastral area of Sekule, Močenok and Nitra river basin. Model RWEQ have been applied to area near SUA research station Dolná Malanta. Annual soil losses are dependent on input factors for each model. Maximal annual soil loss for c.a. Sekule have been determine 116,9 t.ha-1.y-1, c.a. Tvrdošovce have been determine 157,02 t.ha-1.y-1. An annual soil loss for Nitra river basin varies at northern, middle and southern part because of difference in land characteristics, soil and climate regions. Model RWEQ in area of Dolná Malanta predict maximal soil for months March and April from 1,519 to 2,107 kg.m-2.
Key words:wind erosion, wind erosion intensity determination, dust sampler, WEQ, RWEQ
