IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
Surface water drainage system is one of the most important elements of urban planning and areas which incorrect or
inaccurate design of them causes irrecoverable problems for human settlements and other land uses. Inundated cities
and the physical damages due to the floods (in buildings, public spaces, etc.), public health and disaster management
and emergency acts costs are some kinds of problems due to inadequate urban drainage systems. Rapid population
growth, urban development and industrialization of communities increase the acceleration of the problems and provide
new problems like sanitary and safety problems, water pollution problems, increasing the flood intensity and flash floods
in downstream, decreasing base flow etc. Mitigation measures of urban flood effects and their control will implement
through the accurate design of suitable load capacity of drainage networks; consideration of the system¡¯s functions as
an object lead designers to simulation some different scenarios by models like empirical models, mathematical models
or laboratory physical models. This research has simulated one the Tehran sub basins by SWMM, the mathematical
model that developed and presented by Environmental Protection Agency of USA (EPA) for modeling the quantity and
quality of surface runoff. In this simulation, kinematic wave method (solving flow continuity equation in unsteady state
and manning equation) has been applied to flood estimation and surface channelized flow elements was utilized. Flood
routing in channels was considered and calculated within dynamic wave method. Final results showed that some zones
of drainage system are not efficient; then reparation and adjustment measures presented. Additionally regarding to
modeling validated results, SWMM considered as suitable model for simulation of urban runoff in this case study field.
