Soil erosion is a serious agricultural and environmental problem considered as threat to sustainable development around the world. Rainfall primary cause of soil erosion, what leads knowledge its potential (rainfall erosivity – R-factor) be valuable tool for design land conservation best practices. As Brazil has lack information about rainfall erosivity, present paper determined R-factor 141 pl...

This paper addresses the issue of incorporating a digital elevation model into the mapping of Ž . annual and monthly erosivity values in the Algarve region Portugal . Besides linear regression of erosivity against elevation, three geostatistical algorithms are introduced: simple kriging with Ž . Ž . varying local means SKlm , kriging with an external drift KED and colocated cokriging. Cross val...

Soil erosion is time compressed into a number of episodic erosive rainfall events with an associated potential to detach and transport soil particles (rainfall erosivity), each possessing unique spatial temporal characteristics. Rainfall erosivity in Europe follow extreme value distributions which limited rainstorms dominate the long-term budget available energy. To combat targeted manor, timel...

Abstract. Rainfall erosivity quantifies the effect of rainfall and runoff on rate soil loss. Maps are needed for erosion assessment using Universal Soil Loss Equation (USLE) its successors. To improve maps that currently available, hourly daily data from 2381 stations period 1951–2018 were used to generate new R-factor 1-in-10-year event EI30 mainland China (available at https://doi.org/10.1227...
