Abstract :

In this paper, geostatistical methods has been used for optimization of groundwater observation wells network inTabriz plain, North West of Iran. Existing network of observation wells in Tabriz plain have been formed of154Wells and the distribution is not optimal. Data of existing observation wells network and also quality andquantity network is used in order to optimization. By Comparison of different geostatistical models, forsimulation of water level changes in Tabriz plain and choosing the best model, three methods of reduce, increaseand change in the location of wells was followed to optimize existing network. The results showed that byreducing the number of wells to 64%, Water levels in areas without information can be estimated withreasonable accuracy. Increasing the number of wells did not improved statistical criteria, but change in thelocation of some wells causes increase of accuracy of kriging fitted to the data.
