'Salinisation and expansion of hypoxic conditions will intensify in eutrophic estuaries, especially in mid and high latitudes with microtidal regimes .' 'The effects of warming will be more pronounced in high-latitude and temperate shallow estuaries with limited exchange with the open ocean  and seasonality that already leads to dead zone development  .' Interaction between SLR and changes in precipitation will have greater impacts on shallow than deep estuaries . Estuaries characterised by large tidal exchanges and associated well-developed sediments will be more resilient to projected SLR and changes in river flow . Human activities that inhibit sediment dynamics in coastal deltas increase their vulnerability to SLR .
