Spatio-Temporal Modeling of Sodium Adsorption Ratio (SAR) in Groundwater: The Case of Gaza Strip

Abstract

In this paper we consider the geostatistical analysis methods to explain the dependency of the Sodium Adsorption Ratio (SAR) in the groundwater datasets throughout the Gaza Strip. The spatio-temporal ordinary kriging is used to estimate the SAR values for the period 2001 to 2009. The results show positive increasing trend in the SAR values over the time that may seriously deteriorate the quality of the irrigation and drinking water in the Gaza Strip.
