Abstract(s)

The paper focuses on reconstruting a plateau icefield susface from field geomorphoçogical data and a physical-based glaciar model. The results allow the analysis of the patterns of glacial erosion and estimation of the palaeo-Equilibrium Line Altitudes (ELA). The study area is the Serra da Estrela, a plateau in Central Portugal rising to ~2000 m ASL. The glaciated area during the Last Maximum of the Serra da Estrela Glaciation (LMGSE) was ~66km2. The reconstrution of the topography of the icefield and vlley glaciers in the LMGSE is based on the Schiling and Holin model.
