Pedogenic features considered to be produced by subsurface flow were observed on the hillslopes of a zero‐order basin in the Judean desert where the mean annual rainfall is 230 mm. The basin, some 5000m2 in area, is composed of soft chalk covered by soil material, with slope gradients ranging from 30‐60 per cent. A comparison of carbonate, gypsum, and soluble salts distribution within the soil, and also their characteristics in this study area, to the same variables in other arid environments, allows one to determine and analyse pedogenic indicators of subsurface flow. In particular gypsic crusts, which exhibit specific characteristics not observed in other areas where pedogenic features are controlled by vertical limited leaching, highlight the existence of lateral subsurface flow. The spatial distribution of these pedogenic indicators within the basin and in the soil was analysed in terms of soil water regime, soil thickness, and the permeability of the soil and bedrock.
