Description :
In order to predict the root effect more accurately, this experimental study aims at gaining more insight into the importance of root architecture, soil and flow characteristics to the erosion-reducing potential of roots during concentrated flow. Treatments were 1) bare, 2) grass (representing a fine-branched root system), 3) carrots (representing a tap root system and 4) carrots and fine-branched weeds (representing both tap and fine-branched roots). The soil types tested were a sandy loam and a silt loam. For each treatment, root density, root length density and mean root diameter were assessed. Discussion of the results.
