The interrill erosion for a sandy loam soil

摘要

This paper resumes a laboratory experience on a slope adjustable plot with the aim of examining the role of rainfall intensity and slope gradient for a sandy loam soil,typical of Southern Italy,with particular initial moisture content.The results of the simulations performed show that a rainfall reduction causes a corresponding percentage reduction of sediment output.A similar behaviour can be attributed to slope gradient,while runoff moderately increases with rainfall intensity but it is not sensitive to slope gradient.Data also highlight that the degree of saturation can affect runoff and soil loss values.
