Abstract(s)
Understanding the role of the vadose zone is essential to accurately assess hydrogeological
systems and their respective groundwater resources. The study area (Manteigas – Nave de Santo
António – Torre sector, Serra da Estrela Mountain, Central Portugal), presents specific geological,
morphotectonic and climatic characteristics which influence the hydrogeological regime. The vadose
zone has particular features that contribute to control both the quantity and the quality of the groundwater
resources. The regional characterisation of this zone was carried out in terms of the structure, the
soil, including the broad physical, chemical and mineralogical features and the soil hydraulics. The study
included field work focused on geological and pedological features, soil permeability field tests, laboratory
tests (including soil water retention at different pressure heads and clay mineralogy) and mathematical
modelling. Water retention data were used to derive the parameters of van Genuchten’s water
retention curve. Unsaturated hydraulic conductivity was estimated using the Gardner mathematical
