TITLE:

CRITICAL RAIN THRESHOLDS IN THE MUNICIPALITY OF MACEIÓ-AL: A STATISTICAL

CORRELATION BETWEEN RAINFALL AND MASS MOVEMENTS

KEY WORDS:

critical threshold, slopes; landslides; rainfall; rainfall correlation, risk management.

SUMMARY:

The relationship between rainfall and landslides represents an important tool for creating warning systems and
developing a mass movement mitigation plan in the city of Maceió - AL. Mass movements are those defined as
being natural events of soil and/or rock movement along a slope under the direct action of gravity, which can be
added by other transport agents, which reduce the resistance of slope materials and can induce a plastic and fluid
behavior of the soils. Landslides result from the disruption of equilibrium conditions, defined by geological,
geomechanical and climatic factors, with rainfall playing a fundamental role in triggering these processes. Rain is
a major trigger for landslides. The construction of the proposed model will start from the analysis and compilation
of rainfall events that resulted in landslide processes in the municipality, based on the evaluation of historical
series of rainfall data, and a database formed from the occurrences of landslides attended in the County. Making 

an empirical correlation of the data that will be considered the accumulated rainfall prior to landslides of 24 h
(mm/24h), 48h (mm/48h), 72h (mm/72h), 96h (mm/96h) 120h (mm/120 ), The correlation and definition of
critical rainfall thresholds, maximum or minimum necessary to trigger rupture processes is of paramount
importance for the monitoring of risk areas, acting directly in the preservation of human lives.
