Zusammenfassung |
This study presents a revised and scale-adapted
Foster-Meyer-Onstad model (Foster et al., 1977) for the
transport of soil erosion sediments under scarce input data, with the
acronym CliFEM (Climate Forcing and Erosion Modelling). This new idea was
addressed to develop a monthly time scale invariant Net Erosion model (NER),
with the aim to consider the different erosion processes operating at
different time scales in the Sele River Basin (South Italy), during
1973–2007 period. The sediment delivery ratio approach was applied to obtain
an indirect estimate of the gross erosion too. The examined period was
affected by a changeable weather regime, where extreme events may have
contributed to exacerbate soil losses, although only the 19% of eroded
sediment was delivered at outlet of the basin. The long-term average soil
erosion was very high (73 Mg ha−1 per year ± 58 Mg ha−1).
The estimate of monthly erosion showed catastrophic soil losses during the soil
tillage season (August–October), with consequent land degradation of the
hilly areas of the Sele River Basin. |
