Small-scale hydraulic model tests will also be performed in either two dimensional umes orthree dimensional basins, depending on the geometry of the problem.

Numerical modellingThe numerical models applied in the project will be used to derive the tsunami current velocityhitting assets that might fail due to the impacts. These models are NAMI DANCE,MOST/GloBouss, Geoclaw, which all are developed by the RAPSODI partners or availablefrom close collaborators.

The development of the tsunami risk assessment modelincludes the application and validation of numericalmodels.

To investigate the impact on structures and buildings, improved roughness information (incl.the so-called large roughnesses) needs to be integrated in the numerical models and calibratedfrom eld data.

The nal outcome will be new modules in the numerical models which are able to model thetsunami ow and provide relevant input to any of the other models being used or developed inRAPSODI. Relevant input would include ow depth, current velocity, ux and travel time oftsunami. This will enable analysis for investigation of:

the impact on structures and buildings

structural, socio-economic and ecological vulnerability models

a model to assess the overall risk.

Hydraulic modellingThe impact of tsunamis on assets is believed to be best investigated by small-scale hydraulicmodel tests in either two dimensional umes or three dimensional basins, depending on thegeometry of the problem.

Hence, the results from the Field data and literature review, a matrix with di erent types ofstructures and buildings including surrounding ground conditions listed against potentialfailure modes and a list of available models and techniques to design for any of thesecombinations, will be used to select speci c types of structures and to investigate impacts onthese structures leading to any of the aforementioned failure modes.

A systematic investigation will be performed especially in areas of the matrix where no or verypoor information is currently available. The outcome of this research will be a novel descriptionof the mechanisms with which many of the structures and buildings may fail under tsunamiimpact.
