“…Only 4% of its total area remained after draining 96% of it. However, the current government has started projects to develop the marshes, as the marshes are now considered one of the most beautiful tourist areas in Iraq [9].…”

“…Water flows from the Hammar Marshes to the Shatt al-Arab and the Shatt al-Arab and Shatt al-Basra rivers through Qarmat Ali, while the central marshes flow up the Euphrates and then, in Qurna, to the Shatt al-Arab. The water flows from the Hawizeh Marsh to the Tigris and Shatt al-Arab [9].…”

It is the result of IOP Publishing doi:10.1088/1755-1315/1002/1/012010 7 natural processes over millions of years due to the exposure of certain areas in the triangle of Nasiriyah, Basra, Al-Amarah, to the flooding of the two rivers, and this water combines, creating a distinctive environment [9]. It is the main nutrient for the waters of the northern Arabian Gulf, and its waters are characterized by low salinity and an abundance of dissolved nutrients such as nitrates and phosphates [6].…”

The study of the reality and concept of the environment of the marshes, both natural and human, and both sides complement each other in terms of the mutual influence between man and the environment, and that this influence refers to the process of adaptation practiced by man to the natural environment, which tries to harness for him to achieve goals, most of which are economic, which are not without harm to the environmental reality of the marshes Such as overfishing and destruction operations such as the drying of large areas, and the reason lies in the lack of interest on the part of governments and ministries concerned with protecting the marshes from various environmental violations and their attempt to develop them Its geographical location and its origin, as for the second topic, we touched on the most important environmental problems that the marshes suffer from in Iraq, and the methods of dealing with the deterioration occurring in the environment of the marshes were included in the third topic. In addition to the suggestions and conclusions and a list of sources and references.

“…It was important to divide the models discussed above into two groups: statistical and numerical. Numerical models, which were often two- or three-dimensional models based on water outflow, tide, meteorology, topography, and other multidimensional information, were used to evaluate the effects of one or more elements in the mechanism of seawater intrusion [ 26 , 27 , 28 ]. The statistical models, which were mostly used for the study of the seawater suppression strategy or the prediction of seawater intrusion, had been based on actual data, taking into account the statistical correlation among variables [ 29 ].…”

Seawater intrusion in the Minjiang River estuary has gravely endangered the water security of the surrounding area in recent years. Previous studies mainly focused on exploring the mechanism of intrusion, but failed to provide a scheme for suppressing seawater intrusion. The three most relevant determinants to chlorine level, which represented the strength of seawater intrusion, were determined using Pearson correlation analysis as being the daily average discharge, daily maximum tidal range, and daily minimum tidal level. Considering the lower requirement of sample data and the ability to handle high-dimensional data, the random forest algorithm was used to construct a seawater intrusion suppression model and was combined with a genetic algorithm. The critical river discharge for suppressing estuary seawater intrusion determined using this model. The critical river discharge was found to gradually increase with the maximum tidal range, which in three different tide scenarios was 487 m3/s, 493 m3/s, and 531 m3/s. The practicable seawater intrusion suppression scheme was built up with three phases to make it easier to regulate upstream reservoirs. In the scheme, the initial reading of river discharge was 490 m3/s, and it rose to 650 m3/s over six days, from four days before the high tide’s arrival to two days following it, and before falling down to 490 m3/s at the end. Verified with the 16 seawater intrusion events in the five dry years, this scheme could eliminate 75% of the seawater intrusion risk and effectively reduce the chlorine level for the remaining 25% of events.
