Abstract

the use of hydraulic and hydrological models can solve the need of officials to ‎reduce flood damage for a specific area, and if they have time and cost ‎limitations, it can Use optimization algorithms to solve this problem, In such a way ‎that according to the available cost and budget, in the shortest time by linking the simulation and optimization models, they reach ‎the desired logical and reasonable answer and reduce the amount of damages to ‎the lowest possible amount. For this purpose, the combined hydraulic model ‎SWMM has been used to determine the flood trends in canals and canals. From ‎the combination of SWMM model and NSGA-II multi-objective meta-exploratory ‎algorithm, the optimal dimensions of the flood channel have been determined, ‎and the analyzes related to the minimization of costs and the prevention of water ‎runoff have been performed in the computational network. The results show that ‎in the return period of 50 years, in the first case (only changes in the height and ‎width of the bridges), there is a 34.2% reduction, and in the second case (changes ‎in the height and width of the canal + bridges), up to a 100% reduction in the ‎amount of water leakage from the network is obtained, which shows the ‎superiority of both cases compared to the case without The design is shown.‏
