Enhancing flood inundation mapping technique using Landsat-based remote sensing and 2D hydrodynamic modeling: a case study of the Bihar flood caused by the Koshi embankment breach

Floods have become more unpredictable and erratic due to the influence of extreme hydroclimatic events. Therefore, obtaining near-real-time, accurate flood inundation maps for such events is essential for effective flood emergency response, which can be achieved by leveraging remotely sensed data. This study integrated high-resolution remote sensing data to enhance flood inundation mapping in a data-scarce South Asian basin, the Koshi River basin. The study considered the 2008 Bihar flood event,
