A study of the Hydraulic properties of the Shatt al-Arab by the Influence of tidal Movement and Feeding of the Tigris River

Le résumé fourni par la source

This study was conducted to diagnose the effect of variables in the movement of tides and the amount of water released from the Tigris River on some hydraulic properties in the course of the Shatt al-Arab, four stations were selected for the study, namely Al-Sada Al-Noor station, the paper factory, Al-Ashar, and Sehan, and included a measurement, which are the cross-sectional area, discharge volume, net discharge, and water levels. According to the tidal movement located within the lunar calendar for the months of Jumadi Al-Akhir, Rajab, Shaaban, and Shawwal for the year 1443 AH, corresponding to the months from January to June 2022, and for a full tidal cycle (13 hours). The results showed that there is a variation in the cross sections between the studied stations in terms of the shape of the section and depths, and there is a spatial variation in the levels of the studied stations and the variation of the daily and monthly tide range spatially and temporally and according to the studied stations and measurement periods in terms of being the period of flood tide or neap tide, as we note the height of this range in the southern part of the river. The water discharges of the tides varied spatially and temporally according to the stations and these discharges increase as we head towards the mouth of the river, and increase in periods of flood tide for periods of the tide, as for the net daily and monthly discharge, it decreased in the paper factory station from the station of Al-Sada Al-Nour by approximately 10 m 3 sec-1 to represent the water consumption of the area between the two stations.
