A new proposal of the classification of irrigation water

Abstract: -A study on surface water quality in the Acaraú Basin, in the North of the state of Ceará, Brazil was performed. Qualitative dynamics of water flowing to the Acaraú River that supplies water to the irrigation project in the area was evaluated. Multivariate Factor Analysis/Principal Component Analysis was used for evaluation of water quality in order to develop a water quality index (WQI) that reflects soil salinity and sodicity risks and water toxicity to plants. From April/2003 to September/2005 water were sa… Show more

“…During earlier years researchers at the United States Salinity Laboratory (USSL) (1954) [1] and Wilcox (1954) [2] established the standards methods for assessing irrigation water. In the year of (2010) Meireles et al, [3] has develop IWQI model using the specific chemical parameters such as electrical conductivity, Magnesium Sodium Potassium Chloride, Bicarbonate and SAR for assessment of groundwater quality and identified its potential for irrigation purposes. Several workers in the world have applied IWQI model for evaluating the quality of water for irrigation use.…”

“…As alterações causadas pelo uso e ocupação do solo por atividades agropecuárias interferem sensivelmente nos processos biológicos, físicos e químicos, podendo ser constatado através de monitoramento da qualidade das águas (MERTEN & MINELLA, 2004 interpretação, e ajuda no acompanhamento peculiar das características do recurso hídrico (LOPES et al, 2008;MEIRELES et al, 2010;ARAÚJO NETO et al, 2014).…”

“…Entretanto, a sua aplicação como um método padrão gera certo grau de subjetividade, pois depende da escolha de variáveis para constituir os indicativos principais das alterações causadas nos corpos hídricos. Por outro lado, permitem analisar e acompanhar as alterações de uma maneira mais direta, promovendo a conversão de várias informações em um único resultado numérico, facilitando a interpretação (ALMEIDA; SCHWARZBOLD, 2003;LOPES et al, 2008;MEIRELES et al, 2010 …”

“…Recentemente, pesquisadores como Palácio (2004); Andrade et al (2008); Meireles et al (2010) As águas utilizadas nos dois campos irrigados são oriundas de fontes distintas, águas superficiais e águas subterrâneas (Tabela 1). Na região de Limoeiro do Norte se emprega as águas do rio Jaguaribe enquanto no município de Quixeré a fonte hídrica são poços com profundidade média de 100 m.…”
