Researchers have developed a multimodal deep learning framework for large-scale flood monitoring and damage assessment across Russia. The system integrates synthetic aperture radar, multispectral imagery, and digital elevation models, creating a 21-channel input. Two water surface detection strategies were compared: a supervised U-Net++ model and the self-supervised AnySat architecture. The study found supervised learning to be more effective under the tested data conditions, though AnySat showed greater stability for scenarios with more unlabeled data or missing modalities during inference. The framework's predictions were used to estimate flood impact, closely matching official assessments for the 2019 Tulun flood, with the exception of material damage due to reliance on open-source databases.
