Popis:	Damage by flood inundation has often occurred in recent years even in urban areas, where water management systems are controlled properly. Advance provision of useful information such as hazard map and evacuation routes to the peripheral people is considered to be necessary in order to prevent and minimize the damage. Development of inundation flow numerical model is, therefore, required to predict flood inundation areas precisely.In the present study, a depth-averaged flood inundation flow model in the Cartesian coordinate system is developed using a CIP method and a SMAC method. The validity of the model was verified by comparing the computed results with existing numerical and experimental ones in the one-dimensional and horizontally two-dimensional fields. As a result, the model was confirmed to be consistent with the existing numerical schemes and be able to reproduce the laboratory experiment with high accuracy.
