摘要:In the present research, two neighbouring calanchi fronts have been monitored by means of repeatedreadings on erosion pins, that were carried out between November 2006 and October 2008. During the monitoringperiod, a gauge station has been recording rainfalls, allowing us to compute the Rainfall-Runoff Erosivity Factorof the USLE model. The research highlighted: i) a general correspondence between rainfalls temporal trends andsurface variation rhythms; ii) alternating erosion and deposition phases result in a retreat of the “calanchi” fronts.
