Rapid urbanization growth and the tendency to settle down on locations with access to vital resources have led communities to live on the areas exposed to natural hazards. A large number of cities of the world are threatened by urban floods, which act very rapidly and in a devastating manner. This study was been examination and evaluation flash flooding of Darband-Golabdarreh catchment and impact it on Tehran city, Iran with attention parameters that are effective like: elevation surface, drainage network, land use, land cover extracted from CN, minimum, maximum and mean of annual precipitation, slop and slope aspect by using Spatial Multi-Criteria Evaluation (SMCE) the zonation. SMCE has potential for assessment of all elements and an effective factor of flood seismicity is presented jointly with good and rational results. Therefore,in order toflood zonationin theareaand classificationofland usemapandalsoto land cover mapwas used fromLandsat ETM+in 2008. The results are showing that because of grading and numerous constructing, this catchments barrier was damaged with neighboring catchments and it has emanated with them so when flood started there is no guaranty that it flow the direction of drainage of this study area. Therefore the most probability for flooding in Tehran is in Manzarieh and Jamaran that are highest region in this city but most of the north-south avenue in Tehran in eastern part of it were plunge in flooding.
