A framework to assess suitability of global digital elevation models for hydrodynamic modelling in data scarce regions

•Discrete datasets are used to assess vertical accuracy of global DEMs.•Global DSMs underestimate the flood inundation extent including flood depth.•Derived DTMs from TanDEM-X 12 using SMRF technique are successful in simulating floods.•FABDEM and derived DTMs are potential replacements to global DS...
