3.1.2. Erosivity in a Degraded Oceanic Climate Setting

Meteorological data of the study area is presented in Table 5. As seen, no dry month exists in the Claise and highest temperatures are recorded during the month of July making the basin subject to continuous precipitation.

MFI was found to be 80, corresponding to the low variability class. This signifies evenly distributed rainfall, thus reducing risks of climate-induced soil erosion [78]. The Bagnouls–Gaussen Aridity Index (BGI) on the other hand, was found to be "0", signifying that the study area corresponds to the humid regime as a result of its oceanic influence. In terms of CORINE erosivity, the Modified Fournier Index (MFI) belongs to class 2 variability (low), while BGI corresponds to class 1 (humid). Accordingly, the erosivity index of the Claise watershed was found to be 2, corresponding to the low erosivity class.
