Many of cities settled on hill slopes are faced with the danger of mass movements based on the lithology, slope angel, percolation and precipitation characteristics. Identification and recognition of the risk of landslides, falls and creeping potential, and their trajectories on urban slopes is one of the major steps for stabilizing these kinds of slopes.After identification of such slopes, recognition of trends and prediction of their future movements is an essential goal. Slope settled cities which are faced to these dangers, used many ways for stabilizing them. The stabilizing methods are expensive but we can reduce our expenses by using geomorphic methods and improving their safety, aesthetic senses in citizens who live around and close to these slopes.We can do these methods in such a way that slopes show a beautiful landscape and are in harmony with nature. Stabilizing slopes makes a sense of safety in in citizens. Urban mangers and planners will improve sustainable urban development by such methods.In this research we used experimental reduction that is used in geomorphology and after reviewing related literature and briefing methodology of stabilizing urban slopes, we considered salinized slopes in Tehran, especially slopes that are prone to mass movements. And then we have considered all methods that could be used for stabilizing them.After land investigations we considered all the methods that were used by Tehran Municipality to organize and categorize these slopes, and compared them to methods that are used in similar cities all over the world.Finally we have found suitable and unsuitable methods and suggested many ways that can be used in Tehran to improve safety and aesthetic senses.
