“…Generally speaking, the toxicity of frequent trace metals and other chemicals is revealed to surge with the growth in both temperature and salinity (Elie & Girard 2014). The average water temperature in the two areas investigated was shown to be high (Ahmed & Ghazi 2014), which supports this finding. Besides, salinity as an influence augmenting the toxicity of pollutants in this instance could be due to the average salinity level of water in the Shatt al-Arab and Shatt al-Basrah Canal (Ahmed & Ghazi 2014).…”

Morphological asymmetry was analysed in two marine fish species Acanthopagrus arabicus and Planiliza klunzingeri, in brackish and freshwater habitats in southern Iraq. For both species, specimens from the Shatt al-Arab River and Shatt al-Basrah Canal exhibited greater asymmetry values for snout length. In both locations examined, the levels of asymmetry of the physical traits increased as the fish grew. The high levels of asymmetry in the two fish species may be linked to heavy metal pollutants in the two aquatic environments studied.

Marine environment is considered one of the richest environments in fauna of benthic marine micropaleontology because of the suitable conditions for living requirements like food, oxygen, sediment texture and salinity. In the current study, a fauna and their distribution were studied according to the depths of subsurface marine sediments from two regions at the NW Arabian Gulf, the first region at Khor Shytanah (Core 1) at the north of the study area representing a sever environment with high currents, and contain more than 95% sand grains, it is of light color, large size, rounded to sub-rounded grains and clean due to the continuous washing and water movement, whereas the second region was near the oil Basrah Port (Core 2) at the south of the study area, where the quite environment with weak currents and fine sand of dark color due to the activity of non-anaerobic bacteria , the region has angular to sub-angular grains. The type of sediment texture was determined at each depth and consisted of silt, sand silt, sand and silty sand. On the other hand, the percentage of calcium carbonate was determined in the sediments to correlates that with the size and density of fauna that live in this area.

“…Furthermore, the model's reliability has been demonstrated in numerous studies focusing on hydraulic simulation and the spread of substances, particularly saltwater intrusion, in both domestic and international river systems. Notable studies include the Sebou estuary area in Morocco [3], the Kobadak-Sibsa river system in Bangladesh [4], the Shatt Al-Arab River in Iraq [5], the Cubatão estuary area in Brazil [6], the lower Mekong river region, and the Saigon-Dong Nai River system in Vietnam [7,8].…”

This study aims to evaluate salinity intrusion propagation in Ho Chi Minh City under the operation of six tidal sluice gates, namely, Ben Nghe, Tan Thuan, Phu Xuan, Muong Chuoi, Cay Kho, and Phu Dinh by utilizing the HEC-RAS model. The outcomes during calibration and validation procedures underscore the high performance of the HEC-RAS model in simulating salinity intrusion over the study area. In particular, R2 and NSE values were higher than satisfactory thresholds of 0.80 for water level and discharge simulations and 0.50 for salinity concentration simulations. Based on the calibrated HEC-RAS model, this study examined the potential influences of sluice gate operations on salinity distribution under different scenarios. Results indicate that salinity concentration would exhibit increasing trends when operating Ben Nghe and Tan Thuan sluices, while the closure of the Phu Xuan and Muong Chuoi sluices would cause a reduction in the salinity concentration within the areas enclosed by these sluices. In addition, the operations of the Cay Kho and Phu Dinh sluices would lead to decreases and increases in salinity concentration in the upstream and downstream areas of each corresponding sluice gate, respectively. Moreover, when closing six sluice gates simultaneously, the salinity concentration inside and outside the sluice gates would decrease and increase, respectively. In general, these findings indicate that salinity concentration and spatial distribution are significantly influenced by the location and structure of each tidal sluice gate.
