Popis: The degradation of soil poses a serious threat to the integrity of buried assemblies such as underground storage tanks, oil and gas pipelines. The effect of soil moisture content and time on the corrosion performance of steel in soils of dissimilar location of Basra (West Qurna, Foe and Majnoon) was investigated using weight loss measurement. The result showed that the corrosion is correlated with the high moisture content of soil and with increase time. Also, at the critical moisture content the corrosively of the considered soils is given in the request: Majnoon > West Qurna > Foe. In order to study the relationship between soil engineering properties and corrosion frequency, statistical analysis was performed. The findings of the site research show times as the most governance impact on the level of corrosion based on the coefficient of correlation. More studies using variance analysis (ANOVA) and multiple regression analysis showed good agreement between experiments and prediction corrosion rate.
