Vegetation controls soil erosion rates significantly. The decrease of water erosion rates with increasing vegetation cover is exponential. This review reveals that the decrease in water erosion rates with increasing root mass is also exponential, according to the equation SEP e b RP where SEP is a soil erosion parameter (e.g., interrill or rill erosion rates relative to erosion rates of bare topsoils without roots), RP is a root parameter (e.g., root density or root length density) and b is a… Expand

Root Strategies for Rill and Gully Erosion Control
Many studies attribute the effects of vegetation in reducing water erosion rates to the effects of the above-ground biomass. The effects of the below-ground biomass on flow erosivity and topsoilExpand

Gully erosion is an important soil degradation process in Mediterranean environments. Revegetation strategies for erosion control rely in most cases on the effects of the above-ground biomass onExpand
How do root and soil characteristics affect the erosion-reducing potential of plant species?
Plant roots can be very effective in stabilizing the soil against concentrated flow erosion. So far, most research on the erosion-reducing potential of plant roots was conducted on loamy soils.Expand
Empirical models for predicting the erosion-reducing effects of plant roots during concentrated flow erosion
Recent research indicates that plant roots can reduce soil erosion rates during concentrated flow significantly. Earlier studies revealed the erosion-reducing effects of plant roots under controlledExpand
Effect of Root Density on Erosion and Erodibility of a Loamy Soil Under Simulated Rain
Abstract Although both aboveground and belowground components of vegetation act together in reducing soil erosion, mainly the aboveground component has received attention in past research. The aim ofExpand
