Rainfall erosivity, soil erodibility and natural water erosion potential in the Huambo region, Angola

Journal of Agriculture and Rural Development in the Tropics and Subtropics, 2021
The use of erosion assessment methods is critical for the sustainability of land use in tropical and subtropical regions, especially in countries lacking national information on soil erosion development, which is the case of Angola. This study aimed to evaluate the rainfall erosivity (R), soil erodibility (K), soil loss tolerance (T) and natural ...

Radar remote sensing reveals potential underestimation of rainfall erosivity at the global scale

Science Advances, 2023
Rainfall kinetic energy (RKE) constitutes one of the most critical factors that drive rainfall erosivity on surface soil. Direct measurements of RKE are limited, relying instead on the empirical relations between kinetic energy and rainfall intensity ( KE-I relation), which have not been well regionalized for data ...

Model of rainfall erosion index for predicting the potential erosion rate by using a rainfall simulator

IOP Conference Series: Earth and Environmental Science, 2020
Abstract The intent of this research is to investigate the rainfall erosion index that has the highest correlation to the surface runoff volume and the amount of soil erosion. In addition, the aim of this research is to determine the effective rainfall erosion index to predict soil erosion based on observations.

Estimation of the erosive potential of rainfall in the municipality of União dos Palmares-AL

OBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA, 2023
Erosivity is the potential capacity of rainfall to cause soil erosion, causing environmental impacts that degrade the soil. This study aims to estimate the erosivity of rainfall and characterize the hydrological pattern of the Municipality of União dos Palmares, Alagoas.
