Abstract
Conducting groundwater quality studies is a practical necessity for obtaining quality information from water resources. Corrosion and sedimentation are important characteristics and quality indicators of groundwater. The
purpose of this study is to analyze the geostatistical potential of corrosion and sedimentation of groundwater as important indicators of aquifer quality in semi-arid regions such as Birjand plain. For this purpose, 27 wells were sampled and geostatistical analyzes were performed by kriging geostatistical method. The results showed that all qualitative components follow the spherical variogram model. The range of effect of the measured indices was from 3220 m (RSI)to 10300 m (TH). The range of effect of LSI and RSI is smaller than the range of effect of their components and looks similar. Due to the inverse relationship between the Rayznr index and the Langelier index, in the western and southwestern parts of the aquifer where the value of the Langelier index and corrosion potential are minimal, in this part of the aquifer the indices are maximum. Also, in the southeast and east of the aquifer, the pH and in the southwest of the aquifer alkalinity is higher than other parts of the aquifer. Due to the direct relationship between the Langelier index and pH, TDS, alkalinity and hardness, the spatial distribution of the LSI index is similar to the distribution of these components and follows a similar trend. In other words, it can be said that the average Langelier index for Birjand plain indicates its corrosion.
Key Words: Langelier index, corrosion, sedimentation, Birjand plain.
