The maps give information about the number of important changes after constructing a hydroelectric power dam in a town during 2 decades.
Overall, there are major changes in town infrastructure in 2 years(1990 and 2010). It is obvious that the whole landscape and building were completely demolished. By contrast, the huge lake has been constructed.
In1990, there was a forest and ancient structure at the northwest and a rare plant area for animals at the west of the river. on the east of the river, there were irrigated farmlands and villages.
Looking at the other map illustrates that the ancient structures, forest, and the area for animals were quite destroyed, instead of them, wide ranges of electricity pylons was constructed and the villages have remained without any changes. At the north of the river, the hydroelectric power dam was established which results in a beautiful lake. Also there was a hotel alongside the lake.
