Introduction Nebkhas stabilized aeolian landforms in arid and semiarid areas which have been formed due to the deposition of sediments around trees, shrubs and bushes (Cooke et al, 2006:61). In addition to the wind pattern, sand resources and other natural factors like topography, rainfall and depth of the groundwater play a role in the formation and development of this landform (Melton, 194...

Nebkhas, as one of the Eoelian Landforms in dry and semi-dry areas, have significant influence in controlling aeolian erosion and the environment stability. The main question of this study concerns different morphometry of nebkhas in two neighbor sites in Daranjir playa and the main factors which control these landforms. area special properties, the variety  of  hydrogeology properties, and the...

  Introduction Research on ancient and recent global environmental change has mainly been based on natural records, such as those preserved in ice cores, loess deposits, tree rings, corals, stalagmites, and deep-sea and lake sediments (Li et al, 2014). These records have been used to reconstruct the Earth’s past climate, environment, and ecological history (Zhou, 2006). However, in the arid an...

In the old Lut playa underneath the hills of nebkhas, the deepening of the waterways and the extent of the expansion of the cones and the nebkha morphometry are evidences of environmental changes. To study the above-mentioned factors, it is necessary to rebuild the morphodynamic conditions of the region. In this research, the changes in environmental conditions of the area are investigated and ...

Environmental crisis and the consequent loss of natural resources are the main reasons which force managers to pursue methods to manage risks and solve environmental tensions. This study was conducted in Samad-Abad as a center of wind erosion located in the southern part of Sarakhs region, Islamic Republic of Iran, near the Turkmenistan border and the Tajan River. Following field investigations...

Nebkhas, which are formed by shrubs, are a common phenomenon in arid and semiarid landscapes and play important roles in preventing soil erosion and nutrient loss. Halocnemum strobilaceum is one of the important indigenous plant species of Mighan playa that can not only protects itself against wind erosion but also reduces sediment removal and can forms Nebkha phenomenon. This study aims at exa...
