Abstract
Groundwater resources are considered as an important development factor. Geo-statistical methods is one of the appropriate interpolation methods to prepare qualitative and quantitative zoning maps. The aim of this research is to investigate the spatial distribution of groundwater elevations and water quality parameters (EC, TDS, CL- and PH) with acceptable precious. Based on cross validation and the values of RMSS, RMS, ASE and ME of the different geo-statistical models used for groundwater quality and quantity data, the Log ordinary Kriging model with Guassin semi-ovariogram were used for TH, the Log universal kriging model with Guassin with linear trend semi-ovariogram was used for EC, the Log universal kriging model with exponential with linear trend semi-ovariogram was used for TDS, the Log universal kriging model with linear trend with panta spherical semi-ovariogram was used for CL- and the ordinary kriging model with Guassin semi-ovariogram was used for PH. then quality and quantity zoning maps of Arak aquifer have been prepared. The results obtained from the comparison of different interpolation methods using selected models indicate that the geo-statistical methods considerably are better than the fixed methods. In addition, the results of zoning maps quantity and quality parameters indicate research, to obtain an optimum monitoring water well network, two submitting (6 wells) and adding (11 wells) wells methods were applied. In general, the results obtained from the zoning quality map indicate that the groundwater quality reduced in central parts of the aquifer.
