In many arid and semi-arid environments around the world, limited rainfall and runoff-runon processes have lead to vegetation patchiness on many types of landscapes. With simulations studies, the AA. address 2 related questions. Firstly, compared
topography. The study was conducted in the Mapimi Biosphere Reserve (Chihuahuan desert, Mexico). The transect crossed a bare zone and the pioneer, central and senescence zones of a stripe. Rainfall simulations were then used to analyse the relationship

This paper describes more closely-controlled laboratory rainfall simulation and runoff experiments in Toronto, Canada, carried out to identify the sequential scour and deposition processes involved, which are ultimately responsible for the regular

. Rainfall simulations experiments were carried out to determine runoff and infiltration characteristics of the bare and vegetated zones. The largest amount of redistribution during these events is found for areas having an intermediate rainfall regime
