Análise da precipitação pluviométrica do município de Caruaru-PE para aplicação no gerenciamento dos recursos hídricos da região

Abstract

Rainfall analysis of a region is essential for the engineering and management of water resources. Rainfall is a phase of the hydrologic cycle responsible for the return of water to the atmosphere, this process happens when water vapor in the atmosphere is condensed in the form of clouds, occurring in rainfall. The weather effects that influence rainfall in Brazil's Northeast region cause uncontrolled irregularities of rainfall distributions resulting low rainfall. The rural zone of Pernambuco already feel this fact, in recent years the region recorded low levels of rainfall, intense periods of dry periods that led the fall of the reservoirs of the region, besides, the rains were insufficient for a recovery of the same. From that moment came the need to improve the setting of the management of water resources throughout the country. The great demand of water use made by several individuals have exacerbated the water availability in the region, are needed effective management mechanisms so that future conflicts will not occur. In this way the objective of this work and make an analysis of rainfall data of the City of Caruaru-PE, presenting an evaluation of three pluviometric stations located in the municipality, using statistical methods needed to correct same as data gaps, and main reservoirs that supply the city, in order to develop tools to assist decision-making on water resource management in the region. The results show that in recent years the lack of rain in the region directly affected reservoir levels that were overwhelmed with the demand of the population. If necessary the conscious use of water by society and control by the bodies responsible.
