Rainfall erosivity in Italy: a national scale spatio-temporal assessment
Soil erosion by water is a serious threat for the Mediterranean region. Raindrop impacts and consequent runoff generation are the main driving forces of this geomorphic process of soil degradation. The potential ability for rainfall to cause soil loss is expressed as rainfall erosivity, a key parameter required by most soil loss prediction models. In Italy, rainfall erosivity measurements are l...
متن کاملSpatial and temporal variability of rainfall erosivity factor for Switzerland
Rainfall erosivity, considering rainfall amount and intensity, is an important parameter for soil erosion risk assessment under future land use and climate change. Despite its importance, rainfall erosivity is usually implemented in models with a low spatial and temporal resolution. The purpose of this study is to assess the temporaland spatial distribution of rainfall erosivity in form of the ...
متن کاملEvaluating the Spatial-Temporal Variations of Rainfall Erosivity and Erosivity Density (A Case Study: Menderjan Watershed, Isfahan Province)
Rainfall erosivity is one of the factors determining the amount of water erosion in the soil. Rainfall erosivity is determined by the total rainstorm energy and the maximum intensity in 30 minutes (I30). Since rainfall erosivity is closely related to the amount and intensity of rainfall, it is expected that the rainfall erosivity would change monthly and seasonally throughout the year. The mai...
متن کاملArtificial neural networks aided annual rainfall erosivity factor values calculation in Poland
Calculation and analysis of annual R-factor local values for 103 stations in Poland were the main aims of this study. Calculations were made by means of single hidden layer perceptron artificial neural network on the base of monthly precipitation totals from years: 1961-1980. For most of the analyzed stations calculated average annual R-factor values were low or moderate, at the range from 50 t...
متن کاملSimulation of rainfall temporal distribution pattern using WRF Model (case study of Parsian dam basin)
During the rainfall, the intensity of precipitation varies. Changes in the amount of precipitation during an event of rainfall are effective in the resulting of flood and its intensity. Knowledge of how rainfall changes over time during rainfall is determined by temporal distribution pattern of rainfall. For this purpose, availability of short-term time scales rainfalls data are important that ...
