| Abstract | Abstract. The principle of optimal interpolation using regionalized variable theory is applied to the spatial analysis of groundwater salinity. Interpolated values of groundwater salinity for Tebrak area in central Saudi Arabia were obtained by the kriging technique in a GIS compatible format and isarithmic map of the kriged values of groundwater salinity was drawn to depict the regional trend of groundwater salinity in the area. The map shows an elongated region of low groundwater salinity extending through the center of the sampled area from northwest to southeast. The estimation error, depicted in the isarithmic map of kriging variance is small in the interior region, where sufficient data were available, which implies high confidence on the interpolated values of groundwater salinity, and increases at the margins. |
