A unique empirical approach of estimating the urban flood warning threshold is presented. First, the rainfall depth-duration relationship was estimated based on radar-gauge merged rainfall data with 1 km–10 min space-time resolution for 319 highly urbanized watersheds of the study area, for the extr...
