NICOP -- Wave-ice modelling in the laboratory - comparison with scaled up studies with real ice covers
Abstract
Proposal title: Wave~ice modelling in the laboratory ~ comparison with scaled up studies with real ice coversA one~year funding is" requested to enable the research team at Nanyang Technological University ~ Nanyang Environment & Water Research Institute, (NTU~ N""EWRI) to participate in the experiments at the Sea~Ice~Wave Interaction (SIWI) facility at the University of Melbourne, and c"onduct the data analysis and comparison with theories after the experiments.The proposed project is a companion and parallel project with another ONRG funded project at NTU~NEWRI entitled ~Wave Impact on Arctic Shipping and Offshore Technology ~ A Unique Mod"eling Facility~, to test wave propagation through floating viscoelastic covers with different rheological properties. This current p"roject is to validate existing wave~ice interaction theories adopted in WaveWatch III~. The validation is a critically important" task to demonstrate the correctness of the model predictions. However, an outstanding task remains to establish the linkage between"" the viscoelastic properties to the actual ice cover conditions (grease ices, pancake ices, etc) in the field.The objective of thi"s proposed project is to address this remaining task by fulfilling the following primary research goals.1. -Investigate the relationship between the wave modulation and attenuation predictions from a sea ice dispersion model with viscoelastic continuum assumptions to actual ice covers in relatively large scale experiments planned in the newly constructed Sea~Ice~Wave Interaction (SIWI) facility at the University of Melbourne.2. -Support and participate in the execution of the wave~in~ice experiments at the University of Melbourne with research manpower and wave surface sensors.3. -Establish the viscoelastic equivalence of the actual ice cover that shal"l be tested in the large scale experiments at the University of Melbourne, by comparing the results to the experiments at NTU with t"rue viscoelastic materials.The proposed project shall continue to contribute to the overarching theme to develop guidelines for safe and economically viable solutions for Arctic shipping and exploration through the use of modelling tools and laboratory testing.
