Shrub patterns and surface hydrological fluxes in a semiarid hillslope Conference Paper uri icon

abstract

  • Climate-vegetation interactions and feedbacks are the subject of many studies and recently, the rainfall-plant-soil interplay in the hillslope scale is in the foci of ecohydrology. As most of the models in this scale rely on synthetic environments, there is a need for studies that use remotely sensed and in-situ data to examine the effect of hillslope hydrological processes on ecosystem functioning and plant population spread in a more realistic manner. A major problem is the difficulty encountered in simulating water budget and measuring vegetation at the individual level. In this research, a typical hillslope was chosen offering variations in slope decline and orientation, soil depth and vegetation cover, at the LTER Lehavim site in the center of Israel (31020'N, 34045'E). The annual rainfall is 290 mm, the soils are brown lithosols and arid brown loess and the dominant rock formations are Eocenean limestone …
