Abstract

Information on CHLORINE concentration in GROUNDWATER for drinking and agriculture is important. If the concentration of this element is in too much water can cause problems for humans and is toxic to plants. Measurement of chloride in GROUNDWATER is extensive, costly and time consuming. Find easy and inexpensive method has a special importance. the Statistical methods are based on spatial variables. Changes of these variables point to the other have a certain continuity. This study for evaluation the ability of GEOSTATISTICAL methods for estimating CHLORINE using auxiliary variables ELECTRICAL CONDUCTIVITY in GROUNDWATER of Mashhad and the surrounding was conducted. For this purpose, 276 wells were sampled and Parameters were measured ELECTRICAL CONDUCTIVITY and CHLORINE.The data with software GS+ were analyzed. To determine the spatial correlation of data, Variograms were calculated and plotted. The results showed good continuity exists between the measured parameters. The correlation between two variables based on the variogram, 0.91 Was calculated.Spherical model for ELECTRICAL CONDUCTIVITY and Gaussian model for CHLORINE based on the minimum amount of RSS as the most suitable model was fitted to the data. For Comparison of methods estimation of the root mean square error (RMSE) and plot of observational and estimated values were used. GEOSTATISTICAL methods, the CHLORINE more accurately than IDW and NDW methods were estimated.
