EXPEDIÇÃO MINDU: ANÁLISE GEOGRÁFICA DO IGARAPÉ DO MINDU

2020, Workshop Internacional Sobre Planejamento e Desenvolvimento Sustentável em Bacias Hidrográficas

Abstract

Water is an important resource for life maintenance and can be used for recreation, transportation, habitat and consumption, among other uses. However, anthropic actions in changing the natural conditions of water resources directly influence the dynamics of this system, making it unsuitable for use. Thus, guided by the concept of risk of Veyret (2007), from an expedition carried out between the months of April and July of 2018, it presents factors related to the risk of flooding in the water course of the Mindu, based on the following variables: River quotas of igarapé; Rainfall indices in Manaus; Drainage density, sinuosity index of fluvial Canal. The analysis of these factors, associated with irregular occupation with self-construction and absence or lack of urban infrastructure, indicates high risk to flooding, mainly in the high and medium course. These two factors, plus the expressive volume of solid residues retained in the margins and bed of the creek, favors the flood risk with loss of water quality and impacts of urban environment.
