“…Although GPR surveys carried out in 2010 and 2011 provided useful results (Sala et al, 2010 & 2011), there were still some anomalies of difficult interpretation, probably due to the specific features of an alluvial environment (David et al, 2008, p. 16). In those contexts, the use of geophysical methods, as part of a more complex multidisciplinary approach to get a better comprehension of subsurface stratigraphy, is a topic that geoarchaeological literature has frequently addressed (Bates & Bates, 2000; Challis & Howard, 2006, p. 231; Goldberg & Aldeias, 2018; Shillito et al, 2019 and references therein). Suggested procedures in these alluvial scenarios usually encourage the definition of hierarchical approaches in which methods for landscape visualisation and archaeological prediction are settled according to the particular scale the project requires (Challis & Howard, 2006, pp.…”
