Elementos para gestão de recursos hídricos da bacia do Igarapé D`Alincourt, Rolim De Moura – RO

Abstract

The current study had as its springboard the promotion of elements that can provide the dialogue about the Water Management (Water Main Plan, 21 Local Agenda, Environment Legislation) in the city of Rolim de Moura – RO. For the theoretical help to the analysis, they used the conceptual bases that are present in the National Legislation of Hydrous Resources (Law 9.433/97), having as a parameter of socio-spatial analysis the Chapter IV, Section I, which rules the Plans of Hydrous Resources, they also tried to analyze the influence of the use and occupation of the soil of Igarapé D’Alincourt basin, when concerning the sustainability (quantity and quality) of the water considering the demand and multiple use, identifying the situation of quality and quantity framework by demand, and based on the CONAMA’s 357/2005 resolution framework by parameters (turbidity, pH, color, coliform, OD and conductivity). The methodology of analysis used was the PSIR matrix of evaluation (Pressure, State, Impact-Response) , which has proved to be usable in situations when the tripod NATURAL RESOURCES/PUBLIC POLITICS/ANTHROPIC ACTION are evaluated through a geo-systemic vision, in a way of orienting the evaluation of the state of the environment, from the factors that make pressure on the natural resources, going through the current state of the environment to the answers that are produced to face the environmental problems in each location. The scenery identified shows the reflection of options of use and occupation of the basin without study of environment vulnerability, indirectly reaching the hydrous resources of Igarapé D’Alincourt Basin, noticeable by the tendency to floods that have been happening to its downstream; presence of erosion of the hydrous channels in third order level, extrapolation of framework according to the demand and multiple uses, and perception of hydrous quality by the dwellers.
