Contruction of a flood risk map on Dinh river’s downstream, Ninh Thuan province in service of rescuing and disaster prevention

The downstream of Dinh river is in Ninh Thuan province, with a large surface slope. In order to assess the impact of floods in addition to the factors of flood depth, inundation time, the velocity of flow during flooding must be included. Up to now, in flood studies, when making flood risk maps, there are often clearly factors such as depth of flood, duration of flood, flow velocity, etc. In order to have a general view to serve practically the rescue operation, flood prevention, we present a new method of flood mapping when incorporating two factors: (i) flood depth and (ii) flow velocity of flooded areas.
