摘要

In this research, we proposed the Synchro Water Index (SWI) to detect widespread inundation extent in a transboundary river basin using the time-series Moderate Resolution Imaging Spectrometer (MODIS) data, a major contributor to progress in international flood monitoring. After removing clouds using the White-object Index (WoI), the multi-temporal processing coupled with in-situ water level data was applied to the 2015 Bangladesh flood for near-real-time nationwide rapid flood monitoring. The preliminary results showed that the maximum inundation area from SWI was underestimated to be smaller than the area from the solo use of modified land surface index, or 32% (29,900 km
