Forest fires are responsible for altering the hydrological dynamics and hydraulic properties of soils, including conductivity. This affects several processes, surface runoff, infiltration into unsaturated zone, leaching transport soil chemical components groundwater. In August 2021 a forest fire burnt 25 hectares pine tree olive groves in southern part Pisani Mountains (Tuscany, Italy). The objective work is to provide characterization in-situ conductivity values soils small catchment intersecting area.To perform rapid repeatable measurements, four replicas Di Prima (2015) automatic single ring infiltrometer were built. These infiltrometers capable performing autonomous test thanks automated data acquisition system their water supply system, reducing disturbances tested material.The infiltrometric survey allowed identification statistically significant differences between vegetational types, unburnt areas. results lower compared with groves. proved be devices also rough mountainous environment.
