Effects of rainfall patterns on runoff and rainfall-induced erosion

International Journal of Sediment Research, 2019
Abstract Rainfall-induced erosion involves the detachment of soil particles by raindrop impact and their transport by the combined action of the shallow surface runoff and raindrop impact. Although temporal variation in rainfall intensity (pattern) during natural rainstorms is a common phenomenon, the available information is inadequate to understand

Rainfall changes and rainfall erosivity increase in the Algarve (Portugal)

CATENA, 1995
Abstract There is evidence that, between hydrological years 1931/2 and 1990/ 1, rainfall changed in the Algarve. There was an annual rainfall increase (+9%) and a 7% increase in rainfall during the rainy period (October to February). Both trends were statistically confirmed by parametric and nonparametric procedures.

On the relation of soil erosion to rainfall erosivity in southeastern Nigeria

Communications in Soil Science and Plant Analysis, 1995
Abstract Concern over soil improvishment and water quality problems associated with runoff and erosion from agricultural lands led to a combination of laboratory simulation and field study aimed at further understanding rainfall‐runoff‐soil loss relationships and also to improve the methods of predicting sediment loss and escape of pollutants during ...

Estimation of Rainfall Erosion Index

Journal of the Irrigation and Drainage Division, 1974
The rainfall erosion index in the Universal Soil-Loss Equation has been intensively studied using an analytic approach. Simplified procedures for its computation have been developed and presented. The methodology ties together the eastern and western portions of the United States and is based primarily upon the rainfall distribution curves as published

Rainfall erosivity map for Ghana

Geoderma, 1996
Abstract Monthly rainfall data, spanning over a period of more than thirty years, were used to compute rainfall erosivity indices for various stations in Ghana, using the Fournier index, c , defined as p 2 P , where p is the rainfall amount in the wettest month and P is the annual rainfall amount.
