Erosion of river banks is reported in several basins, sand extraction is also being carried out, and international standards are being called for in that area, while on the Kura River sedimentation is a problem, as it blocks water flow, especially during periods of low water levels in the river. Due to its extensive lowland areas, Azerbaijan is particularly exposed to risks from flooding. For instance, the Iori/Gabirri River dries up in summer in dry years as result of intensive water abstraction.
