Abstract Nowadays in most countries urban development and imperviousness surfaces areincreased This cause the increase of volume and intensity of surface runoff in urbanwatershed For control and management of these floods the urban storm water drainagesystems are required In this study geographic information system GIS is used for generation storage anddisplay the physical parameters analysis of spatial data hydrologic assessment andcalculating the requirement parameters in rational method With analyzing of spot heightand using raster GIS digital elevation model DEM of case study was determined with 2meter of pixel dimensions Flow direction and flow accumulation maps were determinedfor hydrologic assessment identifying the main flow path and storm water collectiontemplate Using of advanced GIS function 4 catchments are delineated in case study Withgeneration of DEM flow direction and flow accumulation maps for each catchments concentration time map was determined and length of main channel average slope andconcentration time were calculated for using in rational method With analyzing of landuse map and using overlay GIS method private green area and building themes wereoverlaid with land use map Using statistical regression method linear equations wereproduced for computing the impervious area building area and open area for each landuse The results displayed that sport and business land uses had maximum impervious areapercent and medical and historical land uses had minimum value The residential land usesare 97 percent impervious that the minimum value was located in region 9 and maximumvalue in region 7 Business and tourist services land uses having the maximum buildingarea percent In average buildings constitute the 58 percent of residential land uses areathat region 6 with 64 1 percent and region 9 with 46 6 percent having the maximum andminimum value respectively The six distribution functions including Normal twoparameter Lognormal three parameter Lognormal Pearson type III Log Pearson type IIIand Gumbel were fitted to maximum rainfall intensity for durations of 15 to 360 minutes The parameters of each distribution were computed by methods of moments and maximumlikelihood Then based on least square test the Log Pearson type III distribution wasselected for optimum distribution Maximum rainfall intensity is computed for returnperiods of 2 to 200 years Finally Intensity Duration Frequency IDF curves andequations were determined Using rational method the storm water peak discharge wasestimated for 4 catchments in case study The database of these catchments is developed ina vector GIS system for better urban storm water management The softwares were used in this study are Autocad 2005 Arcview GIS 3 3 with itsextensions including Spatial Analyst 2 0a 3D Analyst 1 0 Hydrologic Modeling Geoprocessing and Xtools Excel 2003 Access 2003 and Smada 6 0
