Comprehensive consideration of basin in the view of natural condition is one fundamental solution of ecosystem management that leads to better preservation of natural resources. Changes of land use and climate fluctuations are factors that affect natural cycle of water in ecosystem. Slope of domain, their classification, slope of bed, vegetation, type and shape of land and kind of product cultivated in land, flowing regimes or the way of flow of cortical regime, deep regime, permanent and quarterly regime, lithology and thickness of constructors and type of constructor and runoff existed in a basin accompanied by shape of basin are cases that affect natural dangers of basin. This research regarding method is descriptive-analytic and by benefiting field observation and attributional and library studies considers natural dangers of shanderman basin and the aim of above research is considering natural dangers in Shanderman basin. Considerations shows that in Shanderman basin there are various natural dangers that were related to topography condition, geology, soil, geomorphology, vegetation, hydrology and climate of the region and totally the most danger exist in flood basin and thereafter erosion. In fact most floods has been done due to much rain and caused destruction of communicative roads, destruction of bridge and financial damages to agricultural lands and so on. In recent years by change of land use at basin and destruction of vegetation these dangers has accelerated. It is hoped authorities can have necessary plan for confrontation with existing dangers in Shanderman basin regarding findings of research.
