Espacialidade dos atributos químicos de águas subterrâneas do município de Granito, PE

Abstract: A exploração racional e sustentável das águas subterrâneas se torna atualmente cada vez mais importante, para fins de irrigação. Nas regiões semiáridas a irrigação manejada de forma não adequada pode causar salinização e sodificação do solo e aumento da escassez das águas subterrâneas. O conhecimento do comportamento espacial dos parâmetros de qualidade química das águas subterrâneas é indispensável para um manejo preciso da irrigação. Neste trabalho, buscou-se avaliar a variabilidade espacial dos atributos qu… Show more

“…Regarding the positive correlations at p<0.01 probability level, SB was the attribute that most obtained correlations with pH (0.6), K + (0.4), Ca 2+ (0.7) and Mg 2+ (0.9). According to Moreira et al (2020), for variables that show a negative correlation the results tend to have inverse positions, so as one increases the other decreases; for positive correlations, when one increases the value of the other variable tends to increase as well.…”

“…The range among the evaluated attributes showed values between 15 m for Silt and 101.33 m for PR, according to Gazola et al (2017), Matias et al (2019), Moreira et al (2020) and Lundgren et al (2017), range is the distance up to which there is correlation between the sampled points, being one of the main parameters in geostatistics, as it monitors the evolution of the attributes analyzed.…”

“…The use of geostatistical tools allows constant evaluation of a large number of variables, with the capacity to determine specific management zones, evaluating variables that vary vertically and horizontally throughout the landscape, for the correct and safe use of water without degrading the environment (MOREIRA et al, 2020), and their association with other statistical analyses, for example, correlation and descriptive.…”
