Transport of nutrients from the Seybouse River to Annaba Bay (Algeria, SW Mediterranean).

Freshwater and dissolved nutrient inputs that entered the lower Seybouse River estuary were assessed in 2012 through a fortnightly surface water sampling both at a lower river station and at the estuary outlet. The Seybouse estuary delivered annually 950 × 10 m of freshwater yielding 83 kg N km yr of N-NH and 12 kg P km yr of P-PO. More than 2/3 of the annual inputs of freshwater, Si(OH) and NO entered the sea during the flooding event of late February 2012.
