Multifractalidade dos níveis do rio amazonas para a cidade de tabatinga

Abstract

The present work is a multifractal analysis of the levels of the Amazon River for the city of Tabatinga. The data used was collected between the years 1982 and 2022, and obtained from the official website of the National Water Agency. We obtain the multifractal characterization of the level series from the MF-DFA method. Initially, we sought to clarify some important concepts for understanding the work and from this, we were able to carry out each step of the method. After these procedures we were able to achieve the main objective of this work, which is to characterize the dynamics of the floods and ebbs of the Amazon River near the city of Tabatinga through a multifractal spectrum extracted from the multifractal detrended fluctuation analysis (MF-DFA) method. ).
