“…where v °and T are the velocity amplitude (m s −1 ) and periods (s) of coastal seiches, respectively (Johansson, 2010;Cerralbo et al, 2015;Björk et al, 2017;Lafta, 2021). The sediment particles at M2 could travel toward the land or sea as much as El seiche (< 57 m) for every pulse of coastal seiches unless the u seiche does not strengthen (Figure 11).…”

Moorings and axial surveys using acoustic Doppler current profilers in microtidal Masan Bay were conducted to reveal impacts of coastal seiches on sediment behaviors. The hydrodynamic circulation in the bay was dominated by sluggish tidal and residual currents, with which the coastal seiches with a 1-h period were detected. The coastal seiches velocity (useiche) accounted for approximately 30% of the total velocities, causing back-and-forth water motions along the channel. This was insufficient to resuspend bed sediments without external forcings. Nevertheless, it influenced the suspended sediment concentration (SSC) of turbidity maximum (~40 mg l−1) at the central part of bay, showing SSC anomaly of 8 mg l−1. Although the seiche-induced sediment fluxes were only 1% of the total fluxes due to offsetting effect of bidirectional flows, they reached up to 0.040×10−3 kg m−2 s−1 at each pulse of coastal seiches. Repetitive coastal seiches lifted the sediment particles to the upper layer where they would not have risen if not for seiche vertical motion. However, the distance that the coastal seiches can transport the suspended sediments was too short compared to their transportable amounts. Even if sediment particles within turbidity maximum were advected by coastal seiches, they could not leave the region. This process was intensified toward the land because the useiche slowed down the further as it moved away from the node. As long as the bed sediments were resuspended, the coastal seiches were expected to enhance the potential for water pollution by causing repetitive sediment redistribution.

“…The Euphrates River was closed and there is a sharp decrease in the amount of water arriving from the Karun River. So, the Tigris River is the main source of supplying Shatt Al-Arab with fresh water (Lafta, 2021). The average width of the river is 400 m, and its depths range between 20-8 m (Al-Wahili, 2012).…”

The influence of the suggested regulator barrage of the Shatt Al-Arab river on water level ‎fluctuations was tested by using a one-dimensional model. The numerical model period ‎covered six months in 2017. The performance of the model was evaluated by comparing ‎the estimated water level at two locations, Sihan, and Abu Flous. A good fit between the ‎observed and simulated water levels at the two locations was achieved with root mean ‎square error at 0.13 and 0.06 m, respectively. The model results showed that there is an ‎increase in high water levels near areas located below the barrage in both the spring and ‎neap tidal phases. The increasing of water level below the barrage could be attributed to ‎behave the river as a convergent tidal channel that characterizes by the increasing water ‎level as tidal wave propagated further toward inland areas. The highest increase in the ‎water level reaches about 0.4 m below the barrage. Additionally, the tidal range also ‎increased along the river course. The maximum increase in tidal range reaches about 0.9 m ‎below the barrage. The results obtained could be useful for a general assessment of the ‎hydrodynamic of the Shatt Al- Arab river and could give a general view in the case of the ‎construction of such a barrage to tackle the salinity intrusion problem in this river.

“…For the province of Basrah and several Iranian cities, the Shatt Al-Arab River serves as an international boundary between Iraq and Iran. The river is regarded as a navigation corridor for shipping, oil transportation, and fishing, in addition to being used by people for various of activities that use its water (1). On both river banks, several ports primarily base their operations on tidal conditions (2,3).…”

According to their toxicity, toxic heavy metals such as arsenic, mercury, cadmium, copper, zinc, and lead are believed to be the most harmful to humans, fish, and the environment. Because their levels are rising due to human activities endangering aquatic species and people, the current study sought to ascertain the level of toxic heavy metals in five catfish parts (skin, liver, muscles, gills, and ovaries). In the northern part of the Shatt Al-Arab, catfish samples were collected in March 2022. ICP-MS was used to detect target metal levels. According to the results, arsenic accumulated in the skin and muscles at a rate of 0.22 and 0.21ppm, respectively. In contrast, the levels of arsenic in the various body parts are not statistically different. Additionally, cadmium showed no noticeable variances in the studied body parts. Furthermore, the liver had the most significant copper accumulation 18.72ppm. Furthermore, mercury accumulation in various body parts was shown to vary statistically, with the highest levels in muscles 0.66ppm. In addition, zinc was accumulated in the body parts in the following sequence: gills, ovaries, liver, skin, and muscles, respectively, while in the following sequence: muscles, skin, gills, liver, and ovaries respectively in the lead. Moreover, there were no statistically significant differences in the quantity of zirconium that accumulated. According to the current study, the catfish's body parts did not accumulate toxic heavy metals at high rates. This may be due to study area the environment and the mechanisms of treating these types of metals by catfish.
