  abstract = {{T}he intertidal zones are well recognized for their dynamic nature and role in near-shore hydrodynamics. {T}he intertidal topography is poorly mapped worldwide due to the high cost of associated field campaigns. {H}ere we present a combination of remote-sensing and hydrodynamic modeling to overcome the lack of in situ measurements. {W}e derive a digital elevation model ({DEM}) by linking the corresponding water level to a sample of shorelines at various stages of the tide. {O}ur shoreline detection method is fully automatic and capable of processing high-resolution imagery from state-of-the-art satellite missions, e.g., {S}entinel-2. {W}e demonstrate the use of a tidal model to infer the corresponding water level in each shoreline pixel at the sampled timestamp. {A}s a test case, this methodology is applied to the vast coastal region of the {B}engal delta and an intertidal {DEM} at 10 m resolution covering an area of 1134 km<mml:semantics>2</mml:semantics> is developed from {S}entinel-2 imagery. {W}e assessed the quality of the {DEM} with two independent in situ datasets and conclude that the accuracy of our {DEM} amounts to about 1.5 m, which is commensurate with the typical error bar of the validation datasets. {T}his {DEM} can be useful for high-resolution hydrodynamic and wave modeling of the near-shore area. {A}dditionally, being automatic and numerically effective, our methodology is compliant with near-real-time monitoring constraints.},
