Groundwater quality characteristics that is one of the important index for The Plain water resources planning, has been affected on application. corrosion and scaling is one of the problems of water quality groundwater resources that affect the management of water distribution network. In this study investigated the potential corrosion and scaling of the Dezful- Andimeshk plain. For calculation the potential of corrosion and scaling had been used four indicators, Langlier Saturation Index (LSI), Ryznar Stability Index (RSI), Puckorius scaling Index (PSI) and Larson-Skold Index (LS). For zoning indicator used the kriging and co-kriging method with fit variograms. According to the results, Spherical and Gaussian variogram model were best fitting variogram for spatial correlation of indicators. In addition kriging was the best method for Puckorius and Langlier and co-kriging method for Larson-Skold but there is no difference between the methods for the Ryznar index. In addition the magor part of PLAIN has Scaling problem and anther areas have scaling. To use of ground water in this region should be aeration to remove iron and manganese, cathodic protection, lining, enameling and Painting to prevent corrosion and scaling inhibitors such as phosphate compounds. in addition, Prevent extracted ground water resource reduce the corrosion.
