SURICATES: using on-site analytical technologies as a decision support tool for sediment reuse pilots-and projects

International audienceThe SURICATES project (Masson et al., this conference) is a research initiative funded by the European Union aiming at increasing the reuse of dredged sediments.Despite limitations due to currentwaste status,sediment reuse is an increasing alternative to minerals extraction for civil engineering.Applications for coastal defence, erosion and flood risk mitigation (strengtheningor regeneration of harbour/river banks,beach nourishment) require extensive monitoring programs (pre-works baselineat the site, sediment contamination evaluation during dredging, works monitoring, post-works site control).On-site analytical technologies were developed and tested during previous research projects (CEAMaS, GeDSeT, Lemiere et al., I2SM 2016). While technology development continues, we investigate how far available techniques can be used to facilitate reuse project by allowing rapid on-site decisions, and how far on-site measurements can be reliable for these decisions
