Spatial and temporal variations in rainfall erosivity and erosivity density in South Korea

Catena, 2019
Abstract Rainfall erosivity is one of the key parameters in Universal Soil Loss Equation (USLE), which has been used to predict the amount of soil loss by water for 50 years. Investigating spatial and temporal trends in rainfall erosivity is important for soil and water conservation planning.

Spatiotemporal Variations and Projected Rainfall Erosivity and Erosivity Density in Kazakhstan [PDF]

open access: yes, 2021
In this chapter, the spatial-temporal variation of rainfall erosivity in Kazakhstan in 1970–2017 was investigated. The results showed that the average annual rainfall erosivity in Kazakhstan over the past 48 years was 464 MJ mm ha−1 h−1 year−1. No significant time trend was found in annual rainfall erosivity.

Rainfall erosivity in Europe [PDF]

open access: yesScience of the Total Environment, 2015
Rainfall is one the main drivers of soil erosion. The erosive force of rainfall is expressed as rainfall erosivity. Rainfall erosivity considers the rainfall amount and intensity, and is most commonly expressed as the R-factor in the USLE model and its ...

Calibration and validation of rainfall erosivity estimators for application in Rwanda [PDF]

open access: yesCatena, 2020
Rainfall erosivity is one of the most important erosion factors in tropical humid areas including Rwanda. Its current application in erosion modelling is often restricted to the use of externally validated erosivity indices based on annual or monthly ...

Robustness Spatiotemporal Clustering and Trend Detection of Rainfall Erosivity Density in Greece [PDF]

open access: yesWater (Switzerland), 2019
Soil erosion is affected by rainfall, among other factors, and it is likely to increase in the future due to climate change impacts, resulting in higher rainfall intensities.

Effects of Bulk Density on Sediment Erosion Rates

Water, Air, and Soil Pollution, 1997
By means of a recently developed flume, sediment erosion rates as a function of shear stress and with depth in the sediments have previously been determined for relatively undisturbed sediments from several rivers and lakes. These experiments demonstrated that erosion rates depended on at least the following parameters: bulk density (or water content ...
