In the Lower Mekong River Basin floodplains, rice cultivation is highly crucial for regional and global food security.
However, prolonged flooding can pose damage to rice cultivation and other socio-economic aspects. Yet,
there is no rapid operational inundation forecasting system that can help decision-makers proactively mitigate
flood damages. Here, we integrated the so-called Forecasting Inundation Extents using Rotated empirical
orthogonal function analysis (FIER) framework with an altimetry-based operational Mekong River level forecasting
system and built an operational web application, FIER-Mekong, (https://fier-mekong.streamlit.app/) that
generates daily skillful forecasted inundation extents (>70% of critical success index) and depths in about 3 and
30 s, respectively, with up to 18-day lead times. One of its applications, predicting flood-induced rice economic
losses, is also presented. Had FIER-Mekong being adopted, we estimated that the rice damages, up to 87 and 53
million US dollars during the 2020 and 2021 harvest time, respectively, could have been avoided.
