Abstract

Mosul Dam is one of the biggest hydraulic structures in Iraq. It was constructed in 1986 on the Tigris River in the north of Iraq. The initial storage capacity and water surface area of its reservoir reaches 11.11 km 3 and 380 km 2 respectively at the maximum operation level 330 m a.s.l. The dam was operated in 1986. A total of 56 samples were collected from the bottom of Mosul reservoir covering most of the reservoir area. The results of the analysis of these samples revealed that they were composed of gravel (3.8%), sand (15%), silt (55.5%) and clay (25.7%). The distribution of these sediments indicates that the silt portion represents the highest followed by clay and then sand. However, sand percentages are the highest in the northern zone of the reservoir where the River Tigris enters the reservoir and decreases gradually toward the dam site. In the meantime, silt percentage decreases toward the dam site while the finer fraction (i.e. clay) increases. Keywords.Mosul dam, reservoir sedimentation, sediment size distribution, sediment characteristics.
伊拉克摩苏尔大坝水库河床沉积物分布性质
摩苏尔大坝是伊拉克最大的水利工程之一。它建于1986年,位于伊拉克北部的底格里斯河上。水库初始库容11.11 km2,水库水面面积380 km2,最大运行水位330 m a.s.l., 1986年开始运行。从摩苏尔水库底部共采集了56个样本,覆盖了大部分库区。分析结果表明,样品主要由砾石(3.8%)、砂土(15%)、粉土(55.5%)和粘土(25.7%)组成。这些沉积物的分布表明,粉砂部分最高,其次是粘土,然后是砂。在底格里斯河入库的库区北部砂率最高,向坝址方向逐渐减少。与此同时,泥沙比例向坝址方向降低,而细粒粒(即粘土)增加。关键词。摩苏尔大坝,水库沉积,泥沙粒度分布,泥沙特征。
