Abstract :

The purpose of constructing surface water collection networks is to provide the possibility of securing the city against unforeseen events (cessation) and improving urban health, etc. During the recent rains in Mahshahr port, most of the roads and streets were severely flooded due to the lack of canals and even streams. The purpose of this study is to manage and repel runoff using geographic information system in Mahshahr port. For this purpose, using the geographic information system, first the digital layers of the region including height, slope, slope direction and drainage network of the city were prepared. Then, using fuzzy logic method, spaces with runoff potential in the area were identified. The research findings indicate that the focus of these spaces is in the east, center and northeast and southeast of the region. Then, using the RiverTools technique and according to the map of the city's drainage network, the best routes were prepared for the construction of the proposed canals. These channels include sub-channels, main secondary channels and main secondary channels.
