| Abstract | ||
| The study included properties Djimorvologih General Shatt al-Arab area of convergence in Qurna up downstream in Ras Bisha, and the study showed that the tables feeding downstream of aspects contributed to the spatial variation of the depths of the Hungarian as increasing the depth of (8.5) m in Qurna to (24) m in the vineyard for a fall to (11) in the downstream header (FAO), which makes the linear form of the bottom of the course approaching the form obtuse angle. The tables also helped the formation of islands as much focus islands around (0.45) km / km south of the mouth of the vine. The shape of the cross section of the river tends to regularity, reflecting weak erosion and sedimentation processes in the vicinity of the Hungarian and a tendency to balance with Turkish relative erosion processes in the west side in order to speed stream islands and the tendency of water to the right direction. That straightening Gully made the river tends to the formation of the islands as the average longitudinal form factor about (0.13) and deviate from the island of relegating a high amount of rotation (0.64) that low watery discharge from the (1377) m 3 / s ( 399) m 3 / s accompanied by a decrease in the rates stream islands. Have led draining of the marshes to prevent impact tables emerging from the carving course and deepen into estuaries are ideal for deposition load river, and the lower watery discharge and disconnect the Hungarian tables emerging from Marsh works to weaken the operations of composition islands, is that the decline attributed and plant growth natural Some sewage sub parallel side of the islands helped to increase the deposition and growth of these islands as the island exti | ||
