Adaptation under extreme events: predictive maintenance for risk reduction

Abstract

Increasing human and climatic pressures on coastal systems and their infrastructure has resulted in cumulative loses for ecosystem services (e.g. Sanchez-Arcilla et al, 2022) and increasing degradation of coastal and harbour structures (e.g. Kong and Frangopol, 2004; Speijker et al 2000). The result has been a steady increase in risk levels, both for infrastructures (Al-Najjar, 2007) and coastal habitats (Coanda et al., 2020), compounded by a lack of bespoke predictive maintenance (Hermans et al., 2013). A predictive maintenance programme, linking observations and inspections with numerical and/or experimental analyses of water-sediment-structure-ecosystem interactions, specially under extreme conditions, would reduce coastal risks during the life cycle of coastal structures or habitats (Yang et al 2004; Yang et al 2006; Okasha and Frangopol, 2009).
