Spatio-temporal Geostatistical Modeling of Hydrogeochemical Parameters in the San Diego Aquifer, Venezuela

Abstract

The study is developed a spatio-temporal geostatistical modeling of hydrogeochemical
parameters in the San Diego aquifer, Carabobo State, Venezuela during the period 2015-
2017. The main water compositions corresponding to the water classesare: 1) Bicarbonate
of Calcium and/or Magnesium Ca–Mg–HCO3 (North and Central regions, 95.16 km2,
81.25%) 2) Bicarbonate of Sodium Na–HCO3 (Central and South regions, 19.32 km2,
16.5%), 3) Sulfate or Chloride of Calcium and/or Magnesium Ca-Mg-SO4 and Ca-Mg-Cl
(South region, 0.96 km2, 0.82%), 4) Sulfate and/or Chloride of Sodium Na-SO4 and Na-Cl
(South region, 1.68 km2, 1.43%). The modeling of the whole hydrogeochemical parameters is
represented by J-Bessel function.
