This research is aimed at achieving an efficient digital infrastructure forevaluating risks and damages caused by tsunami flooding . Rather than using complex multiphase debris models, werather use an empirical transportation and deposition model that takes into account the interaction with the main water flow, friction/contact with the ground but also debris interaction . The model is able to capture emerging phenomenons like debrisaggregation and accumulations, and possibly to react on the main flow by creating hills of debris and making the main stream deviate . We believe that this originalunexplored debris approach can lead to a valuable analysis of tsunami flooding damage assessment with Physics-based damage functions . We also discuss the way to derive quantities of interest (QoI) from the debris density and momentum fields. We believe this approach can be used in the debris approach. We hope to use this approach to analyze the debris. The model can help to identify debris accumulations. We also hope to identify emerging debris accumulation and provide an accurate and reliable data on the debris accumulation and debris aggregator for tsunami flooding risk assessment. The research is published in the Journal of Tropical Storm Research, published in January 2014 .
