Erodibility of basin formations is depends on their resistance versus of erosion. In a basin are not the same stones, their resistance and covering area. Obviously, formations sensitivity versus of erosion are determining rate of sediment production in a river. In this research has been analysis formation erodibility versus of erosion in the Sajjadrud basin. Research methods are descriptive–ana...

  In this research we aimed to study the sedimentology of Jajrud River, upstream from Latian Dam. Initially, a field review was conducted to ascertain complete familiarity with the geographical and geological conditions of the proposed region. After determining the sampling location, the acquired samples were taken to the laboratory. From morphoscopic studies of the sediments, we have determ...

The Ab-Barik watershed in Bam is a part of Lut desert basin. It is like all other desert areas which has erosion problems caused by wind erosion, sand and soil storms. The result of these sand storms appears as continuous and isolated sand hills. In this paper it was attempted to identify direction and source of harvest points by using sedimentological methods. This was accomplished by step by ...

The circulation of dust suspended in the air is among the most significant environmental problems in the various regions of the world. However, the primary source of the dust present in the atmosphere is fine-grained particles and These tiny particles are more frequent in arid and semi-arid areas. The Tabas Masina Playa in Iran is one of the regions prone to dust production due to warm and dry ...

Asaluyeh Fishery Port is an old fishery port located in the south-east of the Bushehr Province. The rapid shoreline advancement of the updrift fillet of the main breakwater during past few years and the sedimentation at the port entrance has resulted to substantial difficulties in using the port. The relatively large amount of sedimentation finally affected the navigation at the entrance of the...

Introduction The territory of central Iran is now affected by the hot and dry climate. But, several evidences, such as the extreme erosion of running waters, huge alluvial fans, wide alluvial terraces, and flood deposits indicate colder and wetter climate in the territory (Ghahroodi Tali, 2011: 3). The rivers belong to the most important parts of the sedimentary basin. In fact, the rivers are...
