Abstract (5557 Views)
Aims: Assessing the vulnerability of urban areas to surface water is of particular importance. Destruction of the watershed upstream of urban areas with the destruction of vegetation and road construction and the uncontrolled expansion of urban and industrial lands reduces the infiltration and increases running water, and carries the risk of floods. This study aimed to evaluate the resilience status of the Mashhad water and electricity neighborhood against flood risk.
Methodology: This descriptive study was conducted in 2020. Data collection was performed through library studies, Internet search, and databases, and the required data were extracted from the SWMM model for runoff simulation by combining the Hec-Ras hydraulic model in ARC-GIS software.
Findings: In the study area, low rainfall and short time but with high instantaneous intensities produced higher waterfall peaks than higher rainfall and longer time but with lower instantaneous intensities.
Conclusion: The location to determine the boundary of the floodplain is located on the left side of Laden Boulevard (between Laden 12 to the water and electricity grid), which, even with normal rain, fills the riding area to the edge of the asphalt with water. The northern part of the neighborhood, especially the northeastern part, is more at risk of flooding.
