Ninh Kieu District is an important socio-economic center of Can Tho City. According to statistics in
2019, this region has an average population of 280,792 people, with an area of 29.23 km2. Ninh Kieu district is a
region with relatively low terrain, so urban flooding often occurs due to the impact of rainstorms, high tides and floods
upstream of the Mekong River. This paper presents the results of using Google Earth Engine to interpret Sentinel-1
satellite images to identify flooded areas in Ninh Kieu District from 2018 to 2021. Sentinel-1 satellite image is
selected in this research because of its ability to receive cloud-penetrating data by using radar waves, which Ninh Kieu
District during the research periods had high cloud coverage. The 2019 population data of Ninh Kieu District is used
to determine the number of exposed people in the study area. Research results have shown the location and flooded
area and the number of exposed people, create the basis for building appropriate solutions for managers in this region.
