Abstract : This study is an endeavor to understand tidal currents characterization by measuring speed and direction of the currents in the upper and lower reaches of Khor Abdullah during typical neap and spring tides. The results show that the averages and maximum surface velocities during flood period are great than during the ebb period at station No. 1 at both phase of neap and spring tides. Whereas, this status mutate at station No. 2 during the spring tide and then maximum surface and average velocity were recorded of order of 1.50, 0.94 respectively during the ebb period. Velocities values decline with the depths at both stations. The bottom layer (z/h = 0.95) contain active velocities at each station, therefore, the lowest velocity amounted 0.36 m/sec at station No. 2 during the ebb period of neap tide. Bottom current value percentage to the surface is exceeding 50% of the surface current value at both stations. The relatively high velocities (more than 1.0 m/sec) are restricted to station No. 2 which penetrate for more than water column one third (z/h = 0.40) through some hours of the tide cycle during the flood period. While, like those velocities recess to the surface layer (z/h = 0.05) during the ebb period. Generally, water mass motion seems to be semilinear, so, the currents directed to the northwest between (290°-330°) during the flood and towards southeast between (110°-140°) during the ebb on surfaces and bottom layers.
