The The water of the Shatt al-Arab River is exposed to an increase in salt concentrations, which is an indicator of pollution of the aquatic environment.

This coincides with the climate change and the intensity of demand and storage in Turkey, Iran and central and northern Iraq, the interruption of most of the tributaries that were preparing the Shatt al-Arab water, causing severe saline eruptions in its water course.

And the areas of population concentrations and the other part coming from the Arabian Gulf, and is expected to increase the marine salt penetration in the future more because of the lack of drainage, and is trying to study the nomination of suitable sites to establish a regulatory a Barrier to reduce the effects of the salt tide coming from the south, appropriate surrounding the course of the Shatt al-Arab environment, in order to minimize the damage resulting from the establishment of hydraulic installations and maintain as much as possible of the available water from the Tigris River, which is the only source to feed the Shatt al-Arab after a break of all the tributaries feeding him (Euphrates -Swaib - Garmat Ali and Karun in recent years.

The study showed the possibility of establishing two forms of a regulatory Barrier in the Shatt al-Arab River, one of which is chosen according to the expected future water revenues.

If the water share of the Tigris River continues at an annual rate of discharge not less than 50 m3 /S, As the minimum volume is required to feed the Shatt al-Arab River fresh water in the section extending from the city of Basra to the area of Al Seba and a distance of about 90 km between 50-70 m3 / S, with the need to dig sea channels from the Shatt al-Arab to Khor al-Zubair to orb the flow of marine water During the tide, if it continues the Same rate water from the Tigris River to supply the Shatt al-Arab, which is happening now, if less than the annual discharge of 40 m3/S rate shall be the location best suited to organizational helm in Qurna (South of Swaib River.

).

The study indicated that the selection of the appropriate site for the regulatory Barrier and its design should be suitable for the hydrological nature of the River to achieve the required feasibility.

The study of the environmental and sedimentary impact should be the most important in the nomination of any site of hydraulic origin.

In order to achieve this, As the Shatt al-Arab is an open environment that extends 200 kilometers and has many overlaps and influences, so it must be followed by a few steps for the organizational Barrier to complete the plans to stop the incursion and maintain the limited amount of water revenues to Basra province, which is the furthest from the headwaters of tributaries feeding the Shatt al-Arab River.
