STUDY OF RAINFALL RATES AND EROSIVE PROCESSES AT THE URBAN AREA OF SÃO LUÍS – MA [PDF]

Sociedade & Natureza, 2005
The study of the rain rates is here highlighted, in order to understand the mechanisms that generate the starting point of the erosive processes. The precipitation varies spatially not only in local and regional levels, due to mechanisms that generate ...

Global rainfall erosivity assessment based on high-temporal resolution rainfall records [PDF]

Scientific Reports, 2017
Abstract The exposure of the Earth’s surface to the energetic input of rainfall is one of the key factors controlling water erosion. While water erosion is identified as the most serious cause of soil degradation globally, global patterns of rainfall erosivity remain poorly quantified and estimates have large ...

Rainfall Erosivity in Southeastern Nigeria

Ethiopian Journal of Environmental Studies and Management, 2012
In developing land management plans to minimize erosion problem, it is imperative to provide quantitative information on aggressiveness of storms for identifying areas in the landscape which are sensitive to disturbances. The study established that rainfall erosivity (R) indices over Southeastern Nigeria range from very low to very high erosivity ...

Influence of reservoir impoundment on rainfall erosivity in the Three Gorges Reservoir region of China

Hydrology Research, 2022
New dammed reservoirs are expected to have a significant effect on the regional hydrocycle, but the detailed patterns may not be well understood. Regional climate change is likely to cause soil erosion uncertainty by affecting rainfall erosivity.

A Review of Rainfall Erosivity as a Natural Factor of Gully Erosion [PDF]

, 2017
In this 21st century which is climate change-driven with more extreme rainfall events, gully erosion is increasingly becoming a global environmental problem influenced by both natural and anthropogenic factors.

Projected changes in US rainfall erosivity [PDF]

Hydrology and Earth System Sciences, 2015
Abstract. Downscaled rainfall projections from 21 climate models from the CMIP5 (Coupled Model Intercomparison Project Phase 5) archive are used to estimate future changes in rainfall erosivity in the continental Unites States. To estimate erosivity from rainfall in the absence of sub-hourly data, we have used both daily rainfall values and the ...

Enrichment of organic carbon in sediment transport by interrill and rill erosion processes [PDF]

, 2008
Erosion and loss of organic carbon (OC) result in degradation of the soil surface. Rill and interrill erosion processes on a silt loam soil were examined in laboratory rainfall and flume experiments.

Rainfall erosivity over the Calabrian region [PDF]

Hydrological Sciences Journal, 1997
Abstract Following the results of a study carried out for the neighbouring Sicilian region, this paper reports a study of the applicability of the annual value, Faj, of the Arnouldus index to represent the erosion risk in Calabrian region. Firstly, By using 214 values of the mean annual value of the erosivity index, FF, and a Kriging interpolation ...
