Journal of Hydrology, 2020 Rainfall erosivity is the driving force of soil erosion and it is characterized by a large variability in space and time. In order to obtain robust estimates of rainfall erosivity, long series of high-frequency rainfall data are needed, which are often ...

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 ...

Analyzing temporal changes in climate erosivity using a simplified rainfall erosivity model in Basilicata (southern Italy) [PDF]
Journal of Hydrology, 2008 The objective of this work was to investigate the magnitude, frequency and trends of rainfall erosivity in Basilicata (southern Italy), as an initial step in the study of the consequences of climatic change on soil environments in the central ...

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.

Changes in the spatial and temporal features of rainfall patterns may have important effects on the magnitude and timing of erosive storms, which will in turn result in changes in landscape response. Mediterranean Europe regions are characterized by strong climatic variability, where dry periods are interrupted by pulsing rainstorms throughout the year.

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 ...

AbstractThe Australian Alpine region is highly vulnerable to extreme climate events such as heavy rainfall and snow falls, these events subsequently impact rainfall erosivity and hillslope erosion in the region. In this study, the relationship between extreme rainfall indices (ERIs) and rainfall erosivity was examined across the Alpine region in New ...

Although there are in existence numberless books, many of them of great excellence, dealing with the effects of denudation (Geomorphology) nevertheless long experience and much reading seem to show that the more descriptive side of the subject, the result of the processes, has received more attention than the actual mechanism by which the results have ...

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.
