Soil and water components of banded vegetation patterns

Banded landscapes are comprised of alternating bands of vegetation and bare ground aligned along the contours in arid and semi-arid regions, on very gentle and uniform slopes. The objective of this paper is to review some of the major findings

Effects of grass roots on the erodibility of topsoils during concentrated flow

The aim of this study is to investigate the impact of root density and root length density of grass on the erodibility of root-permeated saturated topsoils. Three plots were established on a sandy loam. Their treatments were bare, low density

Impact of root architecture on 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

Surface runoff and seed trapping efficiency of shrubs in a regenerating semiarid woodland in northern Ethiopia

seeds in the bare inter-plant areas; and that seeds in the latter are more likely to be translocated by runoff to microsites under shrubs than to other open areas. The study area is located in the Geba river catchment, central Tigray, northern Ethiopia.
