Rainfall erosivity in Brazil: A review
CATENA, 2013article i nfo In this paper, we review the erosivity studies conducted in Brazil to verify the quality and representativeness of the results generated and to provide a greater understanding of the rainfall erosivity (R factor) in Brazil. We searched the ISI Web of Science, Scopus, SciELO, and Google Scholar databases and in recent theses and ...

Projected Rainfall Erosivity and Soil Erosion in Central Asia
2021The GCMs (BCCCSM1-1, IPSLCM5BLR, MIROC5, and MPIESMLR) were statistically downscaled using the delta method under Representative Concentration Pathways (RCPs) 2.6 and 8.5 for two periods: “Near” and “Far” future (2030s and 2070s). These GCMs data were used to estimate rainfall erosivity and its projected changes over Central Asia.

Rainfall Erosivity over Rhodesia
Transactions of the Institute of British Geographers, 1976The paper discusses the basis of the determination of the erosive potential of rainfall, termed 'erosivity'. Using bare soil as a standard, a measure linking kinetic energy and a maximum sustained intensity (EI3o) is found to be the most generally applicable erosivity parameter over large areas of Rhodesia.

Rainfall Erosivity in Northeastern Austria
Transactions of the ASABE, 2013Abstract. Rainfall erosivity is the main driver for soil detachment and sediment transport, and represents the climatic factor most influencing the risk of soil erosion at a given site. Our objectives were to explore 15 min rainfall breakpoint data from 51 rain gauges in the northeastern part of Austria to (1) calculate rainfall erosivity values for ...

Effects of rainfall patterns on runoff and rainfall-induced erosion
International Journal of Sediment Research, 2019Abstract Rainfall-induced erosion involves the detachment of soil particles by raindrop impact and their transport by the combined action of the shallow surface runoff and raindrop impact. Although temporal variation in rainfall intensity (pattern) during natural rainstorms is a common phenomenon, the available information is inadequate to understand

Rainfall changes and rainfall erosivity increase in the Algarve (Portugal)
CATENA, 1995Abstract There is evidence that, between hydrological years 1931/2 and 1990/ 1, rainfall changed in the Algarve. There was an annual rainfall increase (+9%) and a 7% increase in rainfall during the rainy period (October to February). Both trends were statistically confirmed by parametric and nonparametric procedures.

Estimation of Rainfall Erosion Index
Journal of the Irrigation and Drainage Division, 1974The rainfall erosion index in the Universal Soil-Loss Equation has been intensively studied using an analytic approach. Simplified procedures for its computation have been developed and presented. The methodology ties together the eastern and western portions of the United States and is based primarily upon the rainfall distribution curves as published

On the relation of soil erosion to rainfall erosivity in southeastern Nigeria
Communications in Soil Science and Plant Analysis, 1995Abstract Concern over soil improvishment and water quality problems associated with runoff and erosion from agricultural lands led to a combination of laboratory simulation and field study aimed at further understanding rainfall‐runoff‐soil loss relationships and also to improve the methods of predicting sediment loss and escape of pollutants during ...

Rainfall erosivity map for Ghana
Geoderma, 1996Abstract Monthly rainfall data, spanning over a period of more than thirty years, were used to compute rainfall erosivity indices for various stations in Ghana, using the Fournier index, c , defined as p 2 P , where p is the rainfall amount in the wettest month and P is the annual rainfall amount.
