Abstract

In the municipality of Hidrolandia in inserted in the Brazilian Northeastern Semi-Arid it presents periods in which possible socio-natural disasters can occur associated with the absence of rain or excessive rain, resulting in droughts and floods. The article aimed to analyze the socio-natural disasters associated with droughts and floods in the municipality of Hidrolândia in the period 1989-2018.Initially, rainfall data were obtained from the Cearense Foundation of Meteorology and Water Resources - FUNCEME for application of the quantile technique, using the method of Pinkayan (1966). Then, disaster situations associated with dry and rainy periods in the municipality were identified, based on analyzes in the documents present in the Database of the Integrated Disaster Information System (S2iD), which present information on the number of people affected, decrees Emergency Situation (SE), State of Public Calamity (ECP) and recognition of socio-natural disasters. Concomitantly, atmospheric systems and teleconnections that interfered in the upper and lower accumulations were identified. The Intertropical Convergence Zone - ZCIT was the atmospheric system that most influenced the formation of rains. El Niño contributed considerably to the occurrence of droughts. At least twelve disaster situations were verified in Hidrolândia in the historical series analyzed.
