The permeability of red soils of Murgia karst area, Apulia Region (Southern Italy), is here investigated. Some in situ permeability test sessions are undertaken on the shallow layers of red soils covering the karstified limestone of Apulian calcareous foreland platform. Test sites are located among the area of Taranto, Bari and north west of Bari. The in situ conductivity measures shows a wide range of variability without a clear relation with the grain size of the soil or with its initial water content. This is a first contribution to understand the hydraulic behavior of these soils. Further investigations are necessary to better understand their permeability and perviousness to rainfall. In fact red soils covering limestone plateau can consistently affect the infiltration processes of rain water together with rain intensity, thus potentially controlling floods and uncontrolled runoff downstream of large karsts area.
