Systematic reconnaissance mapping and registration of slope movements

Cotecchia, V.

Summary The General Report consists of three parts. In part 1 the directions and purposes achieved with landslie mapping works so far published are briefly reviewed. In part 2 the papers contributed to Theme 1 of the Symposium are summarized. In part 3 the Reporter gives a general picture of the forms, content and purposes necessary, in his opinion, for mass movement mapping, above all for medium scale mapping. For this purpose he points out how necessary it is to make, before drawing up the final synthetic map, a series of systematic basic studies and correlations on the different circumstances influencing slope stability (mineralogical, petrological and tectonic characters of rocks; geotechnical properties; tectonics and eustacy; neotectonics and earthquakes; hydrogeology; climatic conditions; vegetation) and how such studies should be collected in analytical maps, catalogues, etc. Next, modern methodologies for data acquisition (registration, coding and data bank; representation of landform and geodynamic processes; remote sensing and aerophotogrammetry; special techniques for investigating landslides; deterministic and statistical models) through the quick methods better suited to systematic reconnaissance of landslide phenomena are discussed. Finally, the data which facilitate forecasting and the difficulties involved in the drawing of maps are stated.
