Definição da taxa de infiltração para dimensionamento de sistemas de irrigação por aspersão

Abstract: RESUMOObjetivou-se, neste trabalho, determinar, dentre as técnicas nele utilizadas, a mais adequada para a definição da taxa de infiltração visando ao dimensionamento de sistemas de irrigação por aspersão. Obtiveram-se os dados de infiltração de água no solo segundo uma malha com espaçamentos variáveis entre pontos de ensaios de infiltração de 1,5; 3; 6; 12; 24; 48 e 96 m, totalizando 97 pontos de ensaio. As discussões relativas aos resultados obtidos pelas técnicas de definição -moda, média harmônica, mediana… Show more

“…Knowing the values of the stable infiltration rate is essential for the development of agricultural projects of irrigation, drainage and conservation of soil and water, the design of irrigation and drainage systems, as well as for the creation of a more real picture of water retention and soil aeration (Pott & Maria, 2003;Cunha et al, 2009). Errors in the calculation of the basic infiltration rate can cause failures in the dimensioning of irrigation projects, decrease the efficiency of the system, increase operation costs, energy expenditure and water consumption and maximize environmental impacts, such as soil erosion, nutrient leaching and salinization, among others (Calheiros et al, 2009).…”

“…Observa-se, na Tabela 1, que os valores das medidas de tendência central média e mediana para VIB da A2 não são semelhantes, que identifica uma distribuição assimétrica, conforme constatado por Calheiros et al (2009). Optando-se pela transformação logarítmica, nova análise descritiva foi efetuada, sendo observado pelo teste de S-W que há evidências de que os dados seguem uma distribuição de probabilidade normal.…”
