The Problem of Expansion in Erosion and Sedimentation Extensions of Drinking Water in Libya: A Case Study of Kufra City

Corrosion problems that occur in all fields in engineering activities cause high negative economic impacts, therefore research into operations of different wear mechanisms is a prerequisite for mitigating the effects of corrosion problems can reduce economic loss. Groundwater is vital and the sole resource in most of the studied region in the city of kufra. In this study, some physical and chemical analysis studies were conducted on the water samples in the study area, which included: pH, total soluble salts, sulfate, chloride, calcium and magnesium. The values of these concentrations in the studied water samples indicate that they constitute a chemically suitable environment for corrosion and precipitation reactions, additionally, the pH values for the studied water samples ranged between (6.02 - 8.2), EC ranges between (266 - 3054) microseism/cm, temperature values ranged from 34.8 C0 to 37.4 C0, TDS between (270 - 1936 ppm). It was found that the Aggressiveness coefficient ranged between (9.03 to 11.58) and this indicates that the water in this region is highly corrosive and the Ryzner coefficient ranges between (8.98 -11.49), which indicates the water condition is the cause of corrosion. The Langelier coefficient index shows that the negative values are the cause of the increase in wear rate values from -2.73 to -0.89.
