Ice-seabed gouging database : review and analysis of available numerical models
Ice gouging or scour may damage structures buried in seabeds, hence research on this subject is important. Numerical modelling is one of the most flexible and least costly methods of studying ice gouging. Previously, information on existing numerical models and their results was scattered in the lit...
