Rainfall erosivity map for Brazil
CATENA, 2004Abstract Rainfall erosivity is the potential ability for rainfall to cause soil loss. Erosivity can be quantified by means of the R factor calculation of the universal soil loss equation (USLE). The purpose of this study was to investigate the spatial distribution of annual rainfall erosivity in Brazil.

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 ...

Linking Gully Erosion and Rainfall Erosivity
International Symposium on Erosion and Landscape Evolution (ISELE), 18-21 September 2011, Anchorage, Alaska, 2011Gully erosion is an ancient and important worldwide problem capable of dramatically increasing sediment yields when active. Rainfall erosivity is a key variable in this phenomenon. However, there are few studies that explore the relationship between rainfall erosivity and gully erosion.

Journal of Hydraulic Engineering, 1985
A combined stochastic and deterministic method has been devel oped to evaluate soil erosion from overland flow. The exponential distributions for rainfall duration and intensity are combined with rainfall-runoff relation ships for discrete storms. A general equation for.sediment discharge is sug gested from dimensional analysis with different sets ...

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.

Eurasian Soil Science, 2010
A model describing rainfall erosion over the course of a long time period is proposed. The model includes: (1) a new equation of detachment of soil particles by water flows based on the Mirtskhulava equation; (2) a new equation for the transport capacity of the flow based on a modified Bagnold equation, which is used in the AGNPS model; (3) modified ...

15-min rainfall depth time series recorded at 51 rain gauges in two Austrian states (Lower and Upper Austria) situated in the northern and eastern part of the country have been used to calculate long-term rainfall erosivities, average erosivities of single storms, and number and average rainfall intensities of these storms.

The phenomenon known as rainfall erosivity (RE) expresses the ability of rainfall to cause soil erosion. Thus, the estimation of RE magnitudes is relevant for understanding how the erosive processes vary in time and space. Considering this, the present thesis explores the main aspects of RE in Brazil.

Rainfall erosivity in Cape Verde
Soil and Tillage Research, 2000This paper presents rainfall erosivity values derived from a 7-year rainfall recording in the Cape Verde islands, Central East Atlantic. The data set consisted of 63 storm events, continuously registered in 15-min intervals. Kinetic energy of storm rainfall corresponded to established values in other tropical locations.
