 Abstract 


The objective of this work is to study the effect of floods on the quality of the groundwater aquifer of the Grombalia region in September 2018. The study established salinity maps and addressed the salinity section to reach this purpose. This approach made it possible to draw curves of the salinity evolution over the entire groundwater surface. The salinity map of the year 2019 which describes the state of the groundwater of Grombalia following the significant flooding in September 2018, shows a remarkable improvement in the quality of the groundwater in all areas of the groundwater compared to previous periods. On the other hand, the salinity has decreased enormously; it varies from 0.32 to 2.8 g/L. The approach of the salinity sections revealed a variety of origins of the salinization of the groundwater. However, they show a close similarity with the shape of the piezometric sections of the groundwater. All the sections that pass through the flood zones illustrate a significant decrease in salinity in May 2019. The salinity does not exceed 2 g/L, even in Sebkhat Melah and irrigated areas. In conclusion, floods have a very positive impact on the water quality of the groundwater aquifer and are the most impactful factor in the variation of the salinity of the groundwater of Grombalia.
