A series of rainfall simulation experiments was carried out at the Walnu Gulch Experimental Watershed, Tombstone, Arizona, to observe the speed at which desert pavement surfaces could be re-established following disturbance. The results
of these field simulations were then compared with numerical simulations to check the extent to which the simulation model of Wainwright et al. (1994) reproduces the effects of raindrop erosion.

This study examines runoff generated under simulated rainfall on Summerford bajada in the Jornada Basin, New Mexico, USA, to examine and quantify the role that changing vegetation, (grassland, shrubland), has played in altering the hydrologic
