title = "Applicability of the double-grid model for flood inundation in small rivers",
abstract = "The objective of this study is to validate the double-grid model in small-scale river during flood event. Recent advances in surveying technology have made it easier to obtain more accurate topographic data. However, the number of grid cells used in the calculation is limited because of heavy computational burden. Double grid model employs two scaled compu tational grids (a fine grid for strong topography and roughness data and a coarse grid for solv ing the governing equations). In this study, the double-grid model proposed by Volp et al. (2013) was applied to flood inundation phenomena in a real small-scale river. The results showed that the double-grid model is capable to simulate the inundation phenomena in small scale rivers with sufficient accuracy and reasonable CPU time. In addition, simulations of the double-grid model are carried out with different ratios of the number of coarse grids and fine grids and results were discussed focusing on the CPU time and computational accuracy.",
