In Arabic Effect of Tidal Phase on Some Physical and Chemical Properties of Khor Al-Zubair, Southern Iraq

الملخص

The hydrodynamic behavior of Khor Al-Zubair (south of Basrah) was studied for a whole year (2017-2018), which is the period of the current study, to find out the extent of its impact on some physical and chemical properties. The current study included measurements (pH, salinity, temperature, dissolved oxygen, turbidity, sulfate, nitrite, nitrate, phosphate) at two stations near Umm Qasr Port and Khor Al Zubair. The results revealed that the highest and lowest salinity values for both stations ranged between (43.2-43.82) ppt, (39.9-42.96) ppt, respectively. The averages of the highest and lowest values of surface water temperatures for both stations ranged between (31.1-32.1) C̊, (28.15-30.3) C̊, respectively. The highest and lowest values of acidity for both stations were (7.5-7.9), (7-7.3), respectively. The highest and lowest concentrations of dissolved oxygen were (8.58-8.6) mg/l and (8.08-8.1) mg/l, respectively. As for turbidity, the highest and lowest values for both stations are (428-431) NTU and (162-172) NTU, respectively. showed that The measurements that were obtained in the two stations (A and B) of some physical and chemical properties of water in the Khor Al-Zubair channel in the tidal cycle (13 hours) for the highest and lowest tides, As well as in spring and neap tide and for each month throughout the study period, there is no clear difference for these values in the study area, and therefore it was found that there is no effect of the tidal phase on these characteristics due to the current hydraulic conditions for the channel.
