| Abstract | ||
| There are many factors contributed in identifying the hydrological system of Shat Al Arab stream. These factors represented in the half daily process of ebb and flew that characterize the north area of Arab Gulf, where flew steam pushed towards the top of the steam and its effect is reflected on longitudinal section of the stream then decreased toward the north. The hydrological system depended on the drainage of Tigris, Euphrates, Karun and Swaib, in addition to the other climate conditions affecting the stream. The declining of the surface also participated in determining the direction of the stream towards the south, which follow the general slope and the nature of Sedimentation of river. The detached of the soil varied in their size accordingly, there was increase in large detached in comparison with the soft one near the stream. This by its turn leads to the variety of Morphological manifestations composing banks and basins. This also played a role in forming the movement of ground water depending on water slope. Stream ability in affecting and decreasing the percentage of ground water of banks was larger in comparing it with percentage of the close basins which also caused the density of vegetation and its diversity. | ||
