Rainfall erosivity over the Calabrian region
Abstract Following the results of a study carried out for the neighbouring Sicilian region, this paper reports a study of the applicability of the annual value, F , of the Arnouldus index to represent the erosion risk in Calabrian region. Firstly, By using 214 values of the mean annual value of the erosivity index, FF, and a Kriging interpolation method, an isoerosivity map is plotted. Then, in...
متن کاملRainfall erosivity in Europe.
Rainfall is one the main drivers of soil erosion. The erosive force of rainfall is expressed as rainfall erosivity. Rainfall erosivity considers the rainfall amount and intensity, and is most commonly expressed as the R-factor in the USLE model and its revised version, RUSLE. At national and continental levels, the scarce availability of data obliges soil erosion modellers to estimate this fact...

15 صفحه اولApplication of GIS in Modeling Rainfall Erosivity Factor (Case Study: Gabric Watershed- Hormozgan Province East South)
If other factors are held constant erosion, soil loss rate is directly proportional to the amount of rain erosion. Various measures have been proposed so far in the world, depending on geographic location, scale, local conditions and the type of measurement are different. A review of studies conducted worldwide and the limited rain gauge equipped, modified Fournier index is calculated based on ...
متن کاملMapping monthly rainfall erosivity in Europe
Rainfall erosivity as a dynamic factor of soil loss by water erosion is modelled intra-annually for the first time at European scale. The development of Rainfall Erosivity Database at European Scale (REDES) and its 2015 update with the extension to monthly component allowed to develop monthly and seasonal R-factor maps and assess rainfall erosivity both spatially and temporally. During winter m...
