The aim of the present study is to investigate the hydrographic characteristics and nutrient salts in the Oualidia lagoon the period between July 2010 and June 2011. The results revealed that most of nutrients are concentrated upstream of the lagoon and decreased as it approaches the sea. The results showed that the impact of anthropogenic inputs was limited in the distribution of nutrient, the values of total phosphorus were below the Broadwater QWQG value (<25 ?g L-1), except during autumn period where the values reach 48 ?g L-1. Also, the relationships between the different nutrient concentrations and the other parameters (pH and suspended particulate matter) were discussed.
