“…Moreover, large estuaries have in many cases become areas of important harbors (e.g., Hudson River A C C E P T E D M A N U S C R I P T estuary, New York City), and now host extensive industrial and port facilities around in the world. The growth of these sites over the last half a century has increased technological risks because of the concentration of central power generation and other heavy industry (Zhao et al, 2014).…”

“…In the last decade (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012), ice melting from Greenland, Antarctic, and Glaciers are the main contributors to the coastal SLR ( Figure 2 in [7]). Understanding local and regional sea level variability in China Seas is fundamental for implementing appropriate adaptation and mitigation measures to local SLR along the "wealth-belt" of China and low-lying coastal communities (e.g., Yangtze River Estuary, [8][9][10]), which are facing an increase in the frequency of flooding [11], salty water intrusions [12], coastline erosion [13] and ecosystem changes [14]. Knowledge regarding sea level acceleration (SLA, note that hereafter "A" in SLA is referred to "acceleration", not the often-used "anomaly") is crucial for future sea level projections.…”

While global mean sea level rise (SLR) and acceleration (SLA) are indicators of climate change and are informative regarding the current state of the climate, assessments of regional and local SLR are essential for policy makers responding to, and preparing for, changes in sea level. In this work, three acceleration detection techniques are used to demonstrate the robust SLA in the China Seas. Interannual to multidecadal sea level variations (periods >2 years), which are mainly related to natural internal climate variability and significantly affect estimation of sea level acceleration, are removed with empirical mode decomposition (EMD) analysis prior to the acceleration determination. Consistent SLAs of 0.085˘0.020 mm¨yr´2 and 0.074˘0.032 mm¨yr´2 in regional tide gauge records are shown to result from the three applied approaches in the Bohai Sea (BS) and East China Sea (ECS), respectively. The SLAs can be detected in records as short as 20 years if long-term sea level variability is adequately removed. The spatial distribution of SLA derived from a sea level reconstruction shows significant SLA in the BS, Yellow Sea (YS) and Yangtze River Estuary.

“…However, projecting the geomorphic adaptation under SLR is challenging given the uncertainties in the future meteorological forcing, marine and fluvial sediment sources, and grain size distribution (Ganju and Schoellhamer, 2010;Elmilady et al, 2019). The SLR rate, as well as its pace relative to the basin morphodynamic response, is also critical to the morphological development (Zhou et al, 2013;Lodder et al, 2019). In addition to the natural development of bed morphology, future anthropogenic activities such as dredging may change the regional bathymetry in estuaries and bays (Ralston et al, 2019).…”

Effects of sea-level rise on tides and sediment dynamics in a Dutch tidal bay

et al. 2020

Sea-level rise (SLR) not only increases the threat of coastal flooding, but may also change tidal regimes in estuaries and coastal bays. To investigate such nearshore tidal responses to SLR, a hydrodynamic model of the European Shelf is downscaled to a model of a Dutch coastal bay (the Oosterschelde, i.e., Eastern Scheldt) and forced by SLR scenarios ranging from 0 to 2 m. This way, the effect of SLR on tidal dynamics in the adjacent North Sea is taken into account as well. The model setup does not include meteorological forcing, gravitational circulation, and changes in bottom topography. Our results indicate that SLR up to 2 m induces larger increases in tidal amplitude and stronger nonlinear tidal distortion in the bay compared to the adjacent shelf sea. Under SLR up to 2 m, the bay shifts from a mixed floodand ebb-dominant state to complete ebb dominance. We also find that tidal asymmetry affects an important component of sediment transport. Considering sand bed-load transport only, the changed tidal asymmetry may lead to enhanced export, with potential implications for shoreline management. In this case study, we find that local impacts of SLR can be highly spatially varying and nonlinear. The model coupling approach applied here is suggested as a useful tool for establishing local SLR projections in estuaries and coastal bays elsewhere. Future studies should include how SLR changes the bed morphology as well as the feedback effect on tides.
