Abstract

Urban flooding is a natural disaster that affects a significant portion of the world’s population most frequently. Due to uncontrolled urbanization and climate change, severe floods are becoming more frequent in urban areas, and this trend is expected to continue in the upcoming years. Although preventing such events is not feasible, advancements in technology have made it possible to identify areas that are vulnerable to flooding using 2-D modeling of critical rainfall events. However, in the case of urban flood modeling it needs a lot of accurate data and is not able to predict accurate flow in the channel if this data is not available. Today world, there are a lot of commercial and open source models available for flood mapping, but these models require a wide range of data to extract good results. This study utilized a straightforward approach for analyzing integrated HEC-HMS and HEC-RAS of an extreme rainfall event that occurred on 13th October 2020 in Hyderabad, India. The study uses HEC-RAS, 2-D hydraulic model integrated with GIS, to generate flood inundation layer and risk maps for the 13th October 2020 event. The flood risk results indicate that the areas categorize the risk level as very low risk (<0.001), low risk (0.001 to 0.5) medium risk (0.5 to 1), high risk (1 to 3), and very high risk (>3) of flooding.
