Short summary
The objective of this study is to enhance the performance of 1D–2D flood models using satellite Earth observation data. The main factor influencing a 1D–2D flood model is the accuracy of the digital elevation model (DEM). Two workflows are introduced to improve the 1D–2D flood model: (1) in the DEM analysis workflow, 10 DEM products are evaluated using the ICESat-2 ATL08 benchmark, while (2) in the flood map analysis workflow, flood extent maps derived from multi-mission satellite datasets are compared with simulated flood maps.
