Abstract

In their 2010 paper, Allsop et al (2010) sought to bring together the latest methodologies for predicting waves and wave overtopping for the dams and reservoirs community and modernise the extant approach. In particular, they argued that the reservoir community should move away from the out-dated wave-run up and freeboard allowance approaches and embrace better-validated approaches that limit overtopping, as used by the coastal community. This followed publication of the EurOtop overtopping manual (Pullen et al, 2007), and included many of the methods discussed there. Since the original publication of EurOtop, there have been several improvements to the principal prediction methods and also to methods to improve predictions in cases where the crest includes a promenade and/or a wall that may include a bull-nose. These updates are especially pertinent with regard to bank full reservoirs or where there is a parapet wall at the crest of the embankment. As such, this paper provides an update to Allsop et al (2010) to incorporate the new methods in EurOtop II (van der Meer et al, 2016).
