The intensity and frequency of extreme weather is increasing in major metropolitan areas around the world, which results in unprecedented urban floods. However, subway systems lack consideration of flood risk, and few studies have assessed risk during flood events from the view of subway travel. In this study, subway travel risk was evaluated by fl...
Urban pluvial flooding caused by extreme rainfall has been increasing globally, thus exacerbating loss of life and damage to property. Accurate and updated real-time forecasts are critical needs for urban flooding response and defense. Big data has opened new avenues for inundation depth prediction in complex urban settings. In this study, a new me...
