  abstract = {{T}he {B}engal {D}elta is a highly complex and vulnerable environment where key dynamical features such as tides, storm surges, salinity, and sediment transport strongly depend on the accurate bottom topography representation. {T}o curb the lack of accuracy of widely used global bathymetry databases in this shallow region, we produced an improved coastal bathymetry for the {B}engal {D}elta through an exhaustive and thorough compilation of 70 nautical charts and river surveys. {W}e merged this bathymetry dataset with a high-resolution digital evaluation model, resulting in a novel, consistent product with unprecedented coverage, from the deep parts of the ocean basin (north of 20 degrees {N}) to the far upstream areas of the delta (around 24 degrees {N}). {T}his new bathymetry reduces errors in the tidal residuals by a factor of 2-3 for most coastal gauges as compared to global tidal models. {T}he best results are obtained for the {H}ooghly {R}iver, where errors are as low as 6cm. {T}he improvement in the mouth of the {M}eghna is moderate, suggesting the possible rapid evolution of the bathymetry due to strong sediment transport. {T}his new bathymetry is expected to significantly improve the modeling of coastal processes such as storm surges in the northern {B}ay of {B}engal.},
