Integrated remote sensing imagery and two-dimensional hydraulic modeling approach for impact evaluation of flood on crop yields

摘要

Graphical abstractDisplay OmittedHighlights?Integrated remote sensing and hydraulic modeling was proposed for flood evaluation.?GPU parallel computing achieves flood simulation at high spatial resolution (30m).?Flow velocity was the most influential factor for crop yield loss by extreme storm.?Power function with flow velocity and yield loss were derived for mountainous area.AbstractThe projected frequent occurrences of extreme flood events will cause significant losses to crops and will threaten food security. To reduce the potential risk and provide support for agricultural flood management, prevention, an
