  • The IMAMOTER-CNR monitored a 10-years period of soil erosion in vineyards of the Piedmont Experimental Vine and Wine Centre, in the Alto Monferrato area (NW Italy). To support and continue the monitoring period, this study applies a spatially-distributed soil erosion model in three vineyard areas characterized by different inter-rows practices, i.e. controlled grass cover (GC), conventional tillage (CT) and reduced tillage (RT). For that purpose, we implemented the Modified MMF model as module for the FOSS GIS SAGA. In order to improve model performance, our implementation of this model includes i) the use of a channel network layer, by which the sediment and runoff are concentrated, ii) the use of a multiple flow direction algorithm for sediment and runoff routing, and iii) a time-span parameter which indicates the number of simulation days. In total, 63 runoff and sediment measurements of single or accumulative rainfall events were used during model evaluation. After preprocessing the input data, the model was calibrated separately for spring, summer and autumn season based on the channel network density which in fact follows the tractor paths. Evaluation of model performance was carried out by using the effectiveness coefficient introduced by Nearing. The results show that the differences between measured and predicted soil erosion are in an acceptable range and imply that the Modified MMF model is not only effective as a monitoring tool but can also be used for simulating different conservation scenarios in order to reduce the soil erosion problem in vineyards.
