Abstract
Factors that cause high spatial variability of water in arid regions include precipitation, soil, physiographic, and vegetation characteristics. The inherent heterogeneity of arid lands causes areas of runoff and run-on at the individual plant scale as well as in large area patterns of banded vegetation and beaded drainage networks where run-on and infiltration spur vegetation growth. To rehabilitate degraded rangeland, it is wise to mimic nature by diverting water to target areas to create islands of hydrologically enhanced productivity or by installing structures, such as water ponding dikes, to promote a landscape change to resemble natural vegetation patterns
