Processes and timescales by which a coastal gravel-dominated barrier responds geomorphologically to sea-level rise: Story head barrier, Nova Scotia

Sea‐level rise (SLR) is considered to be important for barrier behaviour when barriers are swash‐aligned and single‐crested, which is typical of only one part of a barrier's lifeterm. Under such conditions gravel‐barrier retreat rate correlates with mesoscale (sub‐decadal: 102 a) SLR rate is t...

Description
Summary:Sea‐level rise (SLR) is considered to be important for barrier behaviour when barriers are swash‐aligned and single‐crested, which is typical of only one part of a barrier's lifeterm. Under such conditions gravel‐barrier retreat rate correlates with mesoscale (sub‐decadal: 102 a) SLR rate is the critical control on barrier retreat, as mesoscale SLR variation in combination with surge potential is able to raise water level to the elevation threshold sufficient for barrier overwash and hence drive barrier retreat.
