Numerical modeling of tsunami sediment transport is a powerful tool to understand tsunami-induced sediment erosion and deposition. Application of the modeling to paleotsunamis will improve our ability for assessing hazards from earthquakes and tsunamis. Assessment of uncertainties due to incomplete inputs will be an inevitable challenge in the sediment transport modeling of paleotsunamis. Uncertainties from various factors, such as paleo-topography, vegetation, sediment source and tide level, will inhibit systematic comparison of the modeling results and field data, and will obscure the picture of the earthquake and tsunami. Datasets of long-term change in coastal environment, annual and seasonal variation of beach topography and anthropogenic modification of the landscape, as well as framework for quantitative assessment of the uncertainties, will be the keys for effective application of sediment transport modeling to paleotsunamis.
