“…For most estuaries, this will lead to an amplified tidal range, altering the spatial structure of tidal currents [ 10 ]. Any variations in tidal range and currents can then bring about changes to flood risk [ 50 ], extractable tidal energy [ 90 ], mixing and circulation patterns [ 91 ], sediment dynamics [ 23 ], water quality [ 92 ], and vegetation communities [ 26 ].…”

“…Interactions between these mechanisms typically determine the tidal dynamics (e.g., tidal range, prism, current) of an estuary and influence the processes within the estuarine system [ 20 , 21 ]. As such, an accurate prediction of the tidal dynamics is required to assist managers and policy makers in developing long-term estuarine management plans, particularly under accelerating SLR [ 18 , 20 , 22 , 23 ].…”

Estuarine tidal range dynamics under rising sea levels

How an estuary responds to sea level rise (SLR) is complex and depends on energy drivers (e.g., tides and river inflows), estuarine geometry (e.g., length and depth), intrinsic fluid properties (e.g., density), and bed/bank roughness. While changes to the tidal range under SLR can impact estuarine sediment transport, water quality, and vegetation communities, studies on the altered tidal range under SLR are often based on case studies with outcomes applicable to a specific site. As such, this study produced a large ensemble of estuarine hydrodynamic models (>1800) to provide a systematic understanding of how tidal range dynamics within different estuary types may change under various SLR and river inflow scenarios. The results indicated that SLR often amplifies the tidal range of different estuary types, except for short estuaries with a low tidal range at the mouth where SLR attenuates the tides. SLR alters the location of the points with minimum tidal range and overall tidal range patterns in an estuary. Variations in tidal range were more evident in converging estuaries, shallower systems, or in estuaries with strong river inflows. These findings provide an indication of how different estuary types may respond to estuaries and may assist estuarine managers and decision makers.
