ABSTRACT:
Brazilian ecotourism faces the challenge of providing safe experiences in the presence of hazards such as rockfalls and flash floods in waterfall settings. This study presents an integrated workflow for assessing and managing geological–geotechnical risks, applied to a representative case study in Central-West Brazil. The methodology comprised six sequential steps: (a) preliminary assessment (event history, tourism use, and geomorphological controls); (b) field inspection to identify unstable features, perform preliminary classification, and prioritize critical areas; (c) reality capture and in situ testing (georeferenced 2D/3D products, digital structural mapping, Schmidt hammer testing, and JRC–JCS joint condition assessment); (d) laboratory testing to characterize strength and calibrate field-derived parameters; (e) limit-equilibrium stability analyses to identify critical blocks; and (f) runout/reach estimation and risk evaluation. Results were consolidated into maps and reports, together with operational protocols combining structural and non-structural measures, monitoring routines, and closure triggers. Integrating reality capture, investigation, calibration, and modeling reduce uncertainty, shortened response time, and delivers decision-support outputs directly applicable to operations and risk communication in ecotourism attractions.
