“…Our results were compared well with local studies in Sicily and Calabria (Italy), Spain and North Ireland while the results were different in South Portugal. Similar to our results, Grauso et al (2010) expect the higher values in the Catania plain and eastern slope of Iblei mountains while the lowest values are projected in south-east of Palermo. In Sicily, D'Asaro et al (2007) are not expecting an increase of rainfall erosivity in the future.…”

Purpose Sediment delivery from headwater catchments to reservoirs is a serious threat to reservoir sustainability and is a critical issue in Mediterranean environments where water resources are scarce. In this study we assessed the consequences of two landscape management scenarios (natural vegetation recovery and scrub clearance) on soil erosion and sediment yield. The results were analyzed in relation to predicted and measured rates of soil erosion and sediment yield, with the aim of promoting better management practices. Materials and methods The study area was the Arnás River catchment (284 ha), which is located in the central Spanish Pyrenees; the area includes abandoned and poorly managed fields. The combination of the RUSLE and SEDD models of soil erosion and sediment delivery was evaluated in terms of its ability to predict annual rates of sediment yield, using field measurement data for seven water years at the gauging station. The consequences of natural plant succession in other areas of the Spanish Pyrenees and scrub clearance practices implemented by certain regional governments to increase grazing meadow areas and reduce the incidence of wildfires were spatially analyzed using GIS. The main sediment source areas were identified, and their specific and total sediment yields were calculated. Results and discussion The predicted soil loss under existing conditions was 2.6 Mg ha −1 year −1 , with 5% of the surface area affected by rates greater than 2 Mg. The measured sediment yield range was 69-534 Mg year −1 . The maximum sediment yield detected was associated with an extraordinary debris flow. The predicted rates were strongly correlated to measured rates (Nash-Sutcliffe coefficient= 0.72). The main sources were alluvial deposits [specific sediment yield (SSY)=51 Mg ha −1 year −1 ], bare soil (SSY= 12), unpaved trails (SSY=11), lots (SSY=4), and pastures (SSY=1). Under a scenario of vegetation recovery, decreases of 3%, 17%, and 16% in soil loss and sediment delivery and yield (respectively) are predicted, whereas increases of 15%, 5%, and 2% are predicted following scrub clearance practices. Conclusions Coupling the RUSLE and SEDD models enabled estimation of annual values of soil erosion and sediment delivery in monitored and unmonitored catchments of small and medium size, making this approach a useful tool for risk analysis. Management practices that combine fire-risk control, by the implementation of scrub clearance practices, with the effects of plant succession on sediment production are suggested as the best management strategy.

“…Several researchers have used both annual precipitation data and maximum daily and hourly precipitation data to estimate the rainfall erosivity factor in the Mediterranean region [35, 36]. However, the models used in these studies estimate the mean annual rainfall erosivity over several yrs rather than the rainfall erosivity in a particular yr.…”

The erosivity factor in the universal soil loss equation (USLE) provides an effective means of evaluating the erosivity power of rainfall. The present study proposes three regression models for estimating the erosivity factor based on daily, monthly, and annual precipitation data of rainfall station network, respectively. The validity of the proposed models is investigated using a dataset consisting of 16,560 storm events monitored by 55 rainfall stations in southern Taiwan. The results show that, for 49 of the 55 stations, a strong positive correlation false(r2>0.5false) exists between the annual rainfall amount and the annual rainfall erosivity factor. In other words, the estimation model based on the annual precipitation data provides a reliable means of predicting the long-term annual rainfall erosivity in southern Taiwan. Furthermore, the root mean square error (RMSE) and mean absolute percentage error (MAPE) analysis results show that the estimation models based on annual and monthly precipitation data have a more accurate prediction performance than that based on daily precipitation data.
