PR453-205101-R01 Prediction of On-bottom Wave Kinematics in Shallow Water

This report examines a novel methodology for approximate prediction of the on-bottom kinematics in shallow waters and shore approach regions. The method involves simulation of generic shallow water scenarios in the Danish Hydraulic Institute MIKE software by assuming a range of seabed slopes and sea states. The simulation results are compiled in a database and a machine learning model is fitted for fast extraction of the desired surface or bottom data.

The outcome of this scope of work is very useful when a pipeline stability assessment is required in shallow water areas, where no site-specific met-ocean engineering data is available. In the future, this database could be expanded to cover more ranges of input data and be implemented in the PRCI On-Bottom Stability software.
