Geomorphologic elevations of Namak Lake after the last glacier courses

In Central Iran, there are several lakes that are now evaporating of water amount of input. As a result, the dissolved minerals in wet periods than enter this basin has been trailing on the effects dry deposition continues and multiple zones of evaporating mineralization. In Central Iran, there are several lakes that are now evaporating of water amount of input. As a result, the dissolved minerals in wet periods than enter this basin has been trailing on the effects dry deposition continues and multiple zones of evaporating mineralization. This research aims to examine developments of the geomorphologic Lake after the last glacier period to help identify the surrounding evaporating levels. In the study of topographic map 1: 25000 scale digital elevation models, 1: 50000, ETM satellite imagery and field observations and also to help GIS software ERDAS. Techniques of the main components in order to identify the evaporating levels around the Lake were used and the results were evaluated by analysis of field observations. As a result of applying the operator the PCA, Three levels around the Lake were shown that the total they had an area of 1850.95 square kilometers and the maximum showing level confirms the growth of the Lake on the last course was the refrigerator that three zone evaporating gradual drying of the Lake under the impact of reduced precipitation and increased evaporation so far have been, respectively, contain calcareous area (calcite), 201.91 square kilometers, the area district with gypsum salt 435.59 square kilometers (halite) with an area of 1213.45 square kilometers.
