Darband and Golabdareh watersheds are located in the north of Tehran with a combined area of 33 km2. In July 1987, they exprienced a sever
flood that caused immense damages to the northern part of Tehran and claimed number of lives. The objective of the present study is to
investigate the said flood as well as flood frequency in the region. Unfortunately, the existing dischargegauging stations have short records
and there are not enough measurements from past floods. Because of the above problem, rainfall-runoff simulation was identified as the appropriate
way to analyze flood peaks and hydro graph. Among the different models for this kind of simulation, HEC1, HYMO, rational and matrix models
were selected for the purposed simulations. The results show better performance of matrix model. For the flood of July 1987, this model estimated peak flood equal to 356 m3/s.
