The general characteristics of tidal currents in the entrance of the Khor Abdullah at Iraq marine water, located at the northwest tip of the Arabian Gulf, were studied based on realistic current measurements. The velocity measurements used in this study extended to about one year, which was never previously available in this vital region of the Arabian Gulf. The results illustrated that this area is characterized by strong currents exceeding 1 m/s during both ebb and flood tides, driven by local water level variations. The maximum currents recorded during the study period were 1.65 and 1.36 m/s at the ebb and flood tides, respectively. Additionally, the monthly averages of ebb currents are higher than those of flood currents. The harmonic analysis results revealed that the tidal effect explained approximately 98% of the variation in water currents, with the remaining percentage due to residual currents. Among the 35 tidal components used in harmonic analysis, the M₂ component was the main contributor to tidal currents variation in the area, followed by S₂, K₁, N₂, and O₁. The residual current seems to have a low effect on the currents variations in the area, with maximum values not exceeding 0.0677 and 0.058 m/s during the ebb and flood tides, respectively. The results obtained give a general view of the tidal current behavior and could be beneficial for several aspects of marine and coastal engineering as well as shipping and navigation activities in this region.

基于实际的水流测量，研究了位于阿拉伯湾西北端的伊拉克海水的阿卜杜拉湾入口处潮流的一般特征。这项研究中使用的速度测量延长了大约一年，这在阿拉伯湾的这个重要地区以前是从未有过的。结果表明，在当地水位变化的驱动下，该地区在落潮和涨潮时都会出现超过 1 m/s 的强流。研究期间记录的最大水流在落潮和涨潮时分别为 1.65 和 1.36 m/s。此外，退潮的月平均值高于洪水的月平均值。谐波分析结果显示，潮汐效应解释了大约 98% 的水流变化，由于剩余电流而剩余百分比。在谐波分析中使用的 35 个潮汐分量中，M₂成分是该区域潮流变化的主要贡献者，其次是S ₂、K ₁、N ₂和O ₁。剩余水流似乎对该区域的水流变化影响较小，落潮和涨潮期间的最大值分别不超过0.0677和0.058 m/s。获得的结果提供了潮汐流行为的总体概况，可能对该地区的海洋和沿海工程以及航运和航行活动的多个方面有益。
