توزيع الأملاح في مياه شط العرب

الملخص EN

The present study aims to detect spatial and temporal variations of dissolved salts in the Shatt al-Arab River as well as salinity variations in the water column, for the purpose of detecting the extent of mixing and stratification processes and determining the downstream area.

The results of field measurements during the experimental period in (2018-2019) showed a clear geographical variation in the concentrations of salts between the measuring stations, as salts rise southward downstream towards the peak at the FAO station.

Moreover, salt rates have had an increased temporal variations during the summer as is noticeable most of the time with each measurement, whereas the salts decreased in the winter season.

As for the vertical variation of salts in Basra, despite the seasonal variation of the salt concentrations, there was no obvious salt gradation between the surface of the river and its depth, which indicates the activity of mixing.

The high salts in Basra during the summer and autumn seasons, and the ence of application, give a clear indication of the progress of the downstream area to this station.
