Hydrographic study of Shatt Al-Arab estuary in the context of climate change
This paper presents key results (at thefirst time) for the impacts of the North Atlantic Oscillation (NAO), the IndianOcean Dipole Mode (DMI) and the Southern Pacific Ocean Oscillation (SOI) eventson the hydrographic and climatic parameters at the mid of Shatt Al-Arab estuary(i.e. Basrah city centre...
