Rainfall erosivity and climate change: some estimations for the Baltata River basin

Abstract

The paper assesses the possible impact of changes in precipitation due to global warming on rainfall soil erosion in a small river basin. The Modified Fourier Index (MFI) was selected as an indicator of erosivity. Comparison of this index values in two climatic thirty-years (1991-2010 vs. 1961-1990) has showed that due to insignificant changes in the total amount of annual precipitation, a weak level of erosion hazard, caused by rainfalls in the previous period, has remained in the studied basin under conditions of climate change.
