A variational data assimilation (4D-Var) method is proposed to directly assimilate flood extents into a 2-D dynamic flood model to explore a novel way of utilizing the rich source of remotely sensed data available from satellite imagery for better analyzing or predicting flood routing processes. For this purpose. a new cost function is specially defined to effectively fuse the hydraul... https://mandisattictoyers.shop/product-category/board-game-barbie/
