CHARACTERIZATION AND ANALYSIS OF THE RECURRENCE PROBABILITY OF HIDROMETEOROLOGICAL AND GEOMORPHOLOGICAL DISASTERS ON THE PARANÁ COAST
The research aimed to characterize meteorological, hydrological, and geomorphological disasters registered on the coast of Paraná's cities in a period of thirty years (1990-2020) and calculate the return time and probability of recurrence (from 1 to 100 years) of events from the triggering rain...

| Sumario: | The research aimed to characterize meteorological, hydrological, and geomorphological disasters registered on the coast of Paraná's cities in a period of thirty years (1990-2020) and calculate the return time and probability of recurrence (from 1 to 100 years) of events from the triggering rains, in order to analyze the rainfall thresholds in 24h and 96h, seasonally and by disaster categories. The results indicated, in conclusion, that: meteorological disasters accounted for half (50%) of the occurrences; the average rainfall triggering disasters in the coastal region of Paraná was 80.9 mm/24h and 153 mm/96h, being 87.9 mm/24h for hydrological disasters and 44.3 mm/24h for those with geomorphological prevalence; intense events were triggered with volumes of 104.6 mm/24h and 178.4 mm/96h; 56% of the disasters occurred in summer; the megadisaster of 03/11/2011 has a return time of 21.2 years and a probability of annual recurrence of 4.59%, 37.5% in 10 years and 90.9% in 100 years. |
