The article focuses on examining the influence of fluctuations in annual precipitation amount on the quality of surface waters. Water quality was estimated with data on BOD, COD and phosphate–ion concentration within five selected regions of Ukraine. Analysis of the precipitation data (1991 – 2010) showed different regional trends. Using the statistics, determination of the interconnection between precipitation amount and water resources quality were done. The obtained regularities and associated uncertainties can be used for prediction of changes in water resource quality and as a guide for future adaptation to possible climate change.

In this paper, the linear regression model using ANN and the linear regression model using MS Excel were developed to estimate the physico-chemical concentrations in groundwater using pH, EC, TDS, TH, HCO3 as input parameters and Ca, Mg and K as output parameters. A comparison was made which indicated that ANN model had the better ability to estimate the physic-chemical concentrations in groundwater. An analytical survey along with simulation based tests for finding the climatic change and its effect on agriculture and water bodies in Angul-Talcher area is done. The various seasonal parameters such as pH, BOD, COD, TDS,TSS along with heavy elements like Pb, Cd, Zn, Cu, Fe, Mn concentration in water resources has been analyzed. For past 30 years rainfall data has been analyzed and water quality index values has been studied to find normal and abnormal quality of water resources and matlab based simulation has been done for performance analysis. All results has been analyzed and it is found that the condition is stable.

A região Nordeste do Brasil vem sendo alvo de medidas do Estado a mais de um século, na tentativa de solucionar o problema da falta de água em época de secas. O Estado do Ceará, por sua vez, apresenta boa parte de seu território inserido no semiárido brasileiro, uma região caracterizada pelo clima seco, com poucas chuvas e elevada evapotranspiração. A problemática da água existe há bastante tempo, principalmente o acesso em quantidade e qualidade suficientes para atender a população. O presente trabalho tem como tema central a questão dos recursos hídricos, com enfoque no abastecimento humano do município de Cariré, localizado na região noroeste do Ceará. Nosso objetivo consiste em apresentar um panorama de como atualmente a população carireense tem acesso à água potável. A metodologia adotada constitui-se em duas etapas: na primeira, realizamos levantamento de material bibliográfico e a segunda diz respeito a parte prática realizada em saídas a campo. Segundo a ONU, a água é um bem comum e que deve ser de acesso a todos, é um direito humano. Nesta perspectiva, o gerenciamento adequado dos recursos hídricos é essencial para a manutenção da qualidade de vida. Palavras-chave: Recursos Hídricos; Abastecimento Humano; Cariré-Ce. ABSTRACTThe pnortheast region from Brazil has been subject of measures for more than a century in attempts to solve the problems lack of water in dry season. The state of Ceará has a good part of its territorial inserted in Brazilian semiarid, a region characterized by dry climate, short rains and high evapotranspiration. The water issue has existed for a long time, mainly in a sufficient access of quantity and quality to serve the population. Then, this article has as a central theme the water resources focusing on water supply of the Cariré localized at Northeast region from Ceará. Therefore the purpose of the paper is to present a study about how the Carire’s population has had access to potable water currently. The methodology adopted to this research consists of two stages: Firstly it was carried out a survey of bibliographical material and secondly it concerned the practical part carried out in the field trips. In accordance to United nations, water is a commom good and it has to be available to everyone, it is a human rights. In that sense, the proper management of water resources is essential to keep the quality of life.Key-words: Human supply; Water resources; Cariré – Ce. RÉSUMÉLa région du nord-est du Brésil est la cible de mesures prises par l’État depuis plus d’un siècle pour tenter de résoudre le problème de la pénurie d’eau en saison sèche. L’État du Ceará, en revanche, présente une bonne partie de son territoire inséré dans le semi-aride brésilien, région caractérisée par un climat sec, avec peu de pluies et une forte évapotranspiration. Le problème de l'eau existe depuis longtemps, principalement l'accès en quantité et qualité suffisantes pour satisfaire la population. Le travail actuel a pour thème central la question des ressources en eau, en mettant l'accent sur l'approvisionnement humain de la municipalité de Cariré, située dans la région nord-ouest du Ceará. Notre objectif est de présenter un aperçu de la façon dont la population carioca a actuellement accès à l’eau potable. La méthodologie adoptée comporte deux étapes: dans le premier, nous procédons à une enquête sur le matériel bibliographique et le second à la partie pratique réalisée lors des visites sur le terrain. Selon l'ONU, l'eau est un bien commun et doit être accessible à tous, c'est un droit humain. Dans cette perspective, la gestion adéquate des ressources en eau est essentielle au maintien de la qualité de la vie.Mots-clés: Ressources en eau; Approvisionnement humain; Cariré-Ce.
