Cesium‐137‐based erosion‐rate determination of a steep mountainous region

Abstract: Data on quantification of erosion rates in alpine grasslands remain scarce but are urgently needed to estimate soil degradation. We determined soil-erosion rates based on 137 Cs in situ measurements. The method integrates soil erosion over the last 22 y (time after the Chernobyl accident). Measured erosion rates were compared with erosion rates modeled with the Universal Soil Loss Equation (USLE). The comparison was done in order to find out if the USLE is a useful tool for erosion prediction in steep mountai… Show more

“…4). The discrepancies between 137 Cs and RUSLE erosion rates obtained in our study are consistent with the ones shown in Konz et al (2009), who found that 137 Cs erosion rates ranged between 5 and 37 t ha −1 yr −1 , while USLE estimates did not exceed 15 t ha −1 yr −1 . When the data set is studied as a whole, no significant correlation is visible between the two variables (r = 0.49, ns), and an outlier represented by point TA-T25 is clearly evident (Fig.…”

“…The P factor was not applicable in the area and was therefore set equal to 1. In order to estimate the contribution of winter erosion, we calculated a W factor (as done by Konz et al, 2009 for the Alpine factor) to be added to the RUSLE formula, as the ratio between 137 Cs and RUSLE-based soil erosion rates (both in t ha −1 yr −1 and therefore dimensionless):…”
