Here we study the soilscape (soil-landscape) evolution of a field site in thesemiarid zone of Israel. This region, like similar regions around the world,was subject to intensive loess accumulation during the Pleistocene and earlyHolocene. Today, hillslopes in this region are dominated by exposed bedrockwith deep loess depositions in the valleys and floodplains. The drivers andmechanism that led to this soilscape are unclear. Within this context, we usea soilscape evolution model (mARM5D) to study the potential mechanisms thatled to this soilscape. We focus on advancing our conceptual understanding ofthe processes at the core of this soilscape evolution by studying the effectsof fluvial and diffusive sediment transport mechanisms, and the potentialeffects of climatic and anthropogenic drivers. Our results show that, in ourfield site, dominated by aeolian soil development, hillslope fluvial sedimenttransport (e.g., surface wash and gullies) led to downslope thinning insoil, while diffusive transport (e.g., soil creep) led to deeper and more localizedsoil features at the lower sections of the hillslopes. The results suggestthat, in this semiarid, aeolian-dominated and soil-depleted landscape, thetop section of the hillslopes is dominated by diffusive transport and thebottom by fluvial transport. Temporal variability in environmental drivershad a considerable effect on soilscape evolution. Short but intensive changesduring the late Holocene, imitating anthropogenic land use alterations,rapidly changed the site's soil distribution. This leads us to assume thatthis region's soil-depleted hillslopes are, at least in part, the result ofanthropogenic drivers
