    • Abstract


      Diel fluctuations of temperature, dissolved oxygen, carbon dioxide, pH, total alkalinity and chlorosity in the Shatt al-Arab River and the Ashar Canal at Basrah, Iraq were studied. The study covered three 24-hour periods in three different months. Appreciable diurnal changes in the physico-chemical conditions and considerable heterogeneity were noted at the three stations selected. The ranges of diurnal differences between maximum and minimum values of all the parameters studied are provided stationwise.
