| Abstract |
| Due to the country’s exposure to a wave of bad weather and large amounts of rain in the Greater Cairo region, and in view of the fifth Settlement area in New Cairo large amount of rain occurred twice during the previous year, there was an unprecedentedly large amount of rain which had a negative impact on the lives of citizens, property, streets and roads. This study aims to present a project to warn of the possibility of flash floods rain exposure to specific areas in New Cairo such as Fifth Settlement. Some areas will be more exposed than others to collect rainwater and obstruct road traffic and destroying some parts of those roads. Remote Sensing (RS), Geographic Information System (GIS) with field measurements will be the main tools to estimate the flash flood magnitudes and the vulnerable areas. Satellite images of Landsat 8 and Sentinel-2 acquired shortly before and after the flash flood events will be downloaded and processed to map the active contributing channels, interfering urban, the response of natural depressions and storage areas and conveying channels to the flash floods. The results show that about 20% of the study area is categorized under very high risk to flash flood hazards. In contrast, more than 50% of the investigated area is less vulnerable to flood risks. |
