A French experience of continuous scour monitoring on real sites

38th IAHR World congress, Panama city, Panama, 02-/09/2019 - 06/09/2019Controlling the risk of scouring of structures, beds or banks due to natural hazards (floods, floods, extreme hydraulic regimes, dam failures) is a major challenge for sustainable development and land use planning. These processes are the main cause of destruction of buildings (civil engineering structures, earthworks, buildings) during major floods. The SSHEAR project, "Soils, Structures and Hydraulics: Expertise and Applied Research? has been set up to improve scour mechanisms knowledge, to develop innovative experimental and observational tools and hydraulic numerical models at both laboratory and full-scale, and then to build optimized diagnostic, warning and management methods for bridges operators. This paper reports on the ?field approach? task of SSHEAR project.. Among the work carried out, we have investigated whether relatively inexpensive methods using commercial sensors can be implemented. After a shot remembering of the scour parameters to be monitored, the benchmark study and the choice of monitoring devices available on the market have been detailed. The preliminary results presented here show that the challenge is being met
