The TRIQUETRA project aims at creating an evidence-based assessment platform that allows precise risk stratification, and also creates a database of available mitigation measures and strategies, acting as a Decision Support Tool towards efficient risk mitigation and site remediation. The overall approach of Triquetra is based in three distinct steps: (i) Risk Identification, (ii) Risk Quantification an (iii) Risk Mitigation. TRIQUETRA’s data collection will provide an insight to all the variables directly or indirectly connected to CC, comparing them with historical data. New innovative surveying techniques are utilized: Hydrographic surveys, multi-beam sonars, UAVs with optical, multispectral & LiDAR sensors, underwater photogrammetry, laser spectroscopy, novel simulation models and more. By integrating all modules and technologies in TRIQUETRA, a DSS will be developed and validated in actual working conditions in 8 different pilot sites across Europe, spanning a wide range of archaeological periods, CH typology, structures and materials. The DSS will enable stakeholders and decision makers to make the most educated decisions related to risk mitigation and remediation of endangered CH sites. In addition, TRIQUETRA will develop a set of novel nanotechnology based coatings for preserving CH sites, without compromising their authenticity. TRIQUETRA will put together a Knowledge Base platform, comprising all existing methods and techniques for remediating such CH sites, while also developing novel CH protection technologies, going beyond state of the art.
