Su alcune toposequenze di suoli nel Bacino del Rio S'Acqua Callenti (Sardegna meridionale)

Nel presente lavoro vengono descritte e commentate tre sequenze di suoli in funzione della morfologia, studiate in altrettanti piccoli bacini idrografici nel Sarrabus-Gerrei (Sardegna centro-meridionale). Lo scopo principale della ricerca è quello di chiarire alcuni rapporti esistenti tra morfologia e suoli derivati dalle rocce metamorfiche e cristalline diffuse nella zona centrale e meridionale dell'isola. Tale immagine vuole essere anche un contributo alla soluzione di alcuni problemi di cartografia pedologica che si sono manifestati durante i rilevamenti che si stanno effettuando nella suddetta area

Geomorphological processes, forms and features in the surroundings of the Melka Kunture Palaeolithic site, Ethiopia

The landscape of the surroundings of the Melka Kunture prehistoric site, Upper Awash Basin, Ethiopia, were studied intensively in the last decades. Nonetheless, the area was mainly characterized under a stratigraphic/geological and archaeological point of view. However, a detailed geomorphological map is still lacking. Hence, in this study, we identify, map and visualize geomorphological forms and processes. The morphology of the forms, as well as the related processes, were remotely sensed with available high-resolution airborne and satellite sources and calibrated and validated through extensive field work conducted in 2013 and 2014. Furthermore, we integrated multispectral satellite imagery to classify areas affected by intensive erosion processes and/or anthropic activities. The Main Map at 1:15,000 scale reveals structural landforms as well as intensive water-related degradation processes in the Upper Awash Basin. Moreover, the map is available as an interactive WebGIS application providing further information and detail (www.roceeh.net/ethiopia_ geomorphological_map/)
