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.

INTER-URBAN FLOODS MODELING, MANAGEMENT AND VULNERABILITY ANALYSIS APPLYING SWMM IN NORTH PARTS OF TEHRAN.
Author : MAHTAB ASGHARZADEH
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.
