The results of suspended and deposited sediment measurements on the floodplain of An Giang province, Cambodia-Vietnam border, during a flood event in 2018 are presented in this research. Maps for the flooded areas were created using GIS and remote sensing techniques. The discharge was also measured on the floodplain and in the main rivers. Deposition sediment and discharge correlation equations were created. The floodplain's inundation area was 35,765 hectares, according to Landsat interpretation. The amount of silt deposited dropped as you got further away from the main channels. According to the findings, the total deposited sediment mass transported to the floodplain during a single flood event in 2018 was 5.023 million tonnes (14.04 kg/m2), down from previous years. Reduced sediment and related nutrients will have a detrimental influence on agricultural productivity in the floodplain, resulting in a major impact on the region's biological environment and economic development.
