Rainfall erosivity in interrill areas: Insights about the choice of an erosive factor
Catena, 2019 Defining a suitable erosive factor for interrill erosion has been a long-going discussion that was not resolved by experimental results.: Insights about the choice of an erosive factor. In this paper, by using computational fluid simulations of individual raindrop impacts, the relevance of four erosive factors was assessed for a range of soil ...

International Symposium on Erosion and Landscape Evolution (ISELE), 18-21 September 2011, Anchorage, Alaska, 2011
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.

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.

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 ...

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 ...
