Possibly silly question coming...
I live near a large, tidally affected and brackish river about 20 km from the coast. The mean height of the river here is about 1.5 m above sea level.
In the ten years I've lived here, sea levels at the coast have risen by 3cm.
Would the mean river height here likely have risen by this much? A little higher? Or a little lower? (assuming the only change is sea level rise, and that flows are constant, etc)
Three cm might seem like two-tenths of sod all, but with 20,000 properties or so affected (not necessarily damaged) in the last major flood, I figure 3cm would add 100-200 to the total.
For an individual property 3cm could be the difference between losing and keeping your carpets, or your ceiling insulation, etc
