Soil Salinity Dynamic and Water Quality in a Ramsar Saline Inland Wetland: Case Study—Bazer-Sakra Sabkha, Setif (North-East Algeria)
Salinization affect ecosystem to a level where it cannot provide environmental services to its full potential. Therefore, understanding the dynamics of salt in the soil and the quality of water resources is of utmost importance. The aim of this study is the assessment of the dynamic of soil salinity and the quality of water (saline lake, groundwater) in RAMSAR wetland (Bazer-Sakra sabkha: northeastern Algeria). 6 water samples were sampled in April 2016) and 8 soil profiles sampled at three depths (0–20 cm, 20–40 cm; 40–60 cm) across a toposequence in April 2016 and 2017. The results show that groundwater r samples range from saline to very saline. The saline lake presents a high risk of eutrophisation because of its high nitrate (128 mg/L) and phosphorus (1031 mg/L) content. For soil salinity, the results reveal two patterns of evolution in salinity profile. The first one is an evolution from shape B (High salinity in the middle) in 2016 to a salinity profile of Shape A (Ascending) in 2017. The second pattern is an evolution from a descending salinity profile (shape C) in 2016 to an ascending salinity profile (Shape A) in 2017.
