Flood is amongphenomenon which bring about considerable damage each year.
This has been attractedgreatly by hydrologists. The factors such as physiography,
geomorphology and human factors can accelerate this phenomenon in basins. For
using water source, flood management, damming, watershed management and the
most basic hydrologic studies, peak discharge is important, so accuracy of studies and
the safeties’ level of the hydraulic structures and establishments are independent to it.
In this research potential flood Zilaki and Firehrud drainage basins were studied by
using of SCS method and finally were compared together. So BasinHydrograph
dimensions calculated by using of 24 hour rainfall, time of concentration, Curve
Number, rainfall excess, time to peak and peak discharge.Then was design
Hydrograph for basins in 2,5,10,25,50,100 period time Results show, because of
physiography of Firehrud basin, It has more ability for making flood than Zilaki basin.
