| Abstract | ||||
| As a result of the changes in characteristics and vitality caused by human inventions, and due to the difficulty of understanding the motives for these changes, the study aimed to link the nutritional state of the Shatt al-Basra Canal to the main reasons for its production for the period from October 2022 to September 2023. Water samples were collected monthly from two stations in the water canal, then the physical, chemical and biological parameters were analyzed including water temperature, dissolved oxygen, salinity, total phosphorus (TP), total Chlorophyll-a (Chl a), and light transmittance (secchi disc depth (SD) in addition to temperature. For water temperature, values fluctuated between 11 & 360C in January and August, whereas the dissolved oxygen was recorded between 4.5 & 11.5mg/ L in June and January. The values of salinity ranged between 48.9 & 20.3 parts per thousand in March and July, and the water light penetration was between 23-55cm in March and August, while a range between 3.5 and 0.6g/ L was recorded for the total phosphorus in March and December. For chlorophyll-a, values ranged from 20.57 to 118.79mg/ L in February and September, while a value range from 46.76-57.89 was assessed for the nutritional state index (TSI) in November and December. Thus, it was deduced that the canal was experiencing a high state of dimerization. Based on the results of the statistical analysis, significant differences were detected between the studied plants at a level of P≥ 0.05 in the second station, where a higher TSI concentration was recorded compared to the first study site. | ||||
