Numerical Assessment of Tidal Energy Resource and Generation Potential for Coastal Bangladesh

The paper contributes to the literature by reconciling the discrepancies among existing national tidal power surveys in Bangladesh through a systematic reconstruction of their methodology and underlying inputs. First, it reconstructs the four published numerical surveys to reveal implicit parameters such as efficiency, basin area, averaging window, and rotor size. Second, it introduces a unified normalized equation (P = kAR^2) for barrage-type estimates, which collapses a factor-of-eleven disagreement across sites down to just 1.3% by isolating three explicit methodological choices. Third, it restores missing unit data in a key monthly dataset, clarifying the resource’s equinoctial seasonal pattern. Finally, it provides a common-basis comparison between tidal range and tidal stream approaches at shared geographic sites, quantifying the comparative output as an equivalent rotor count.
