| Abstract | ||
| This paper aims to analyze the tide heights ( high and low waters ) and time data to explain some physical characteristics of the tide for six months starting from January to June 2012 at four stations distributed along the Shatt Al-Arab River were analyzed.The results show that the Shatt al-Arab River is characterized by tide phenomenon which comes from the Arabian Gulf,tidal wave and its power exposed to decay and dispersion when it progresses to river upstream due to the effect of the current friction with the bottom of the river as well as the river gradient,in spite of this effect the tide wave reaches to the way of Qurna City.The tidal ranges varied between 0.72 meter at the Basra station and 1.72 meter at the Outer Bar station.The maximum and minimum values of highs and lows water are 0-3.1 meter during the study period . Also the study found that there are differences in the values every month during the study period.This is due to the different locations of the stations from the tide power source and also because of the impact of tidal constituents exploited during each month. Diurnal inequality appeared in the study area according to the effect of the declination of the moon.Tidal wave reaches to Basrah station after4-5 hours of occurrence in the outer Bar station while it reaches after about eight hours to Qurna . | ||
