Rainfall pattern and erosion potential in the physiographic regions of the state of Pernambuco, Brazil [PDF]

Revista Brasileira de Engenharia Agrícola e Ambiental, 2018
ABSTRACT The objective of the present study was to characterize the spatial and temporal (2000-2015) rainfall pattern variability and erosive potential in the different physiographic regions of the state of Pernambuco, Brazil. Rainfall data series (3 to 12 years) from 25 weather stations of the state were analyzed. Erosive rainfall events (more than 10

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 ...

Database of rainfall erosivity factor for 141 locations in Brazil.

Latin American Data in Science, 2021
Soil erosion is a serious agricultural and environmental problem considered as a threat to sustainable development around the world. Rainfall is the primary cause of soil erosion, what leads the knowledge of its potential to cause soil erosion (rainfall ...

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.

Assessment of soil erosion in olive orchards (Olea europaea L.) under cover crops management systems in the tropical region of Brazil [PDF]

, 2020
In the tropics, water erosion is one of the most important factors leading to the degradation and deterioration of agricultural land. Olive orchards have a low canopy coverage, especially during the first years after planting, due to the low density of ...

APLICAÇÃO DE MODELOS MATEMÁTICOS PARA ESTIMATIVA DO ÍNDICE DE EROSIVIDADE DAS CHUVAS EM ÁGUA BRANCA – AL / APPLICATION OF MATHEMATICAL MODELS TO ESTIMATE THE RAINFALL EROSIVITY INDEX IN ÁGUA BRANCA – AL

Brazilian Journal of Development, 2020
Soil erosion is the result of work carried out by an erosive agent, which is the potential and active source of the erosion process endowed with energy, which acts on the soil, precipitation.

POTENTIAL EFFECTS OF CLIMATE CHANGE ON RAINFALL EROSIVITY IN THE YELLOW RIVER BASIN OF CHINA [PDF]

Transactions of the ASAE, 2005
Severe soil erosion in the Yellow River basin is a significant obstruction to the sustainable management of soil and water resources. Any changes in soil erosion will have great effects on long-term planning of soil and water conservation in such a severely eroded basin.

Rainfall Erosivity in Soil Erosion Processes

Water, 2020
Regional studies on the erosive power of rainfall patterns are still limited and the actual impacts that may follow on erosional and sedimentation processes are poorly understood.
