Coastal Flooding At Predictable Hours

H/T @bruna Alves | Nature Communications | Editor
“When do coastal floods happen? ⏱️🌊
A new study [link above] shows that, in many tide-dominated coastal regions, flooding tends to occur at specific and recurring times of day. Rather than being completely random, flood events often cluster around predictable hours driven by local tidal patterns.
By analysing coastal flood observations from the UK and the US, [the authors] show[ed] that the timing of flood events can be highly structured, with some locations experiencing floods disproportionately during certain parts of the day.
This adds a temporal dimension to coastal flood risk. We often focus on how frequently floods occur, how severe they are, and where they happen. This study highlights that when they occur may also matter, particularly as rising sea levels increase the frequency of coastal flooding.
The findings provide a useful perspective for coastal adaptation, risk communication, and emergency planning…”

“Flooding is typically perceived as a sudden and unpredictable hazard. Here, [they] show that recurrent flooding can occur at highly predictable times in tidally dominated coastal systems. This predictability stems from phase-locking of tidal constituents and constituent pairs with the solar day, causing peak tides to recur at consistent local times set by regional tidal propagation. Using tide-gauge records from the United States and the United Kingdom, [they] quantif[ied] the intraday timing of coastal flood events and show strong clustering at specific hours, particularly where semidiurnal or mixed tides dominate. For example, floods in Boston cluster around noon and midnight, whereas in southern California they occur in the morning. Sites with stronger non-tidal variability show weaker clustering. This temporal predictability extends beyond nuisance flooding to larger consequential events involving inundation, road closures and infrastructural damage, highlighting opportunities for anticipatory risk communication, emergency planning and time-sensitive coastal adaptation…”

“🌊 New research on long-term coastal flooding as a result of climate inaction 🌊
… The researchers found:
🔷 By 2100 at least an additional 0.5 million people exposed to the 1-in-200 year undefended flood extent - a 25% increase compared to present day.
🔷 Under the most pessimistic storyline by 2300 involving significant ice-sheet instability, an additional 13 million people could be exposed to the 1-in-200 year undefended flood event.
🔷 Under some scenarios there is a need for large-scale movement of populations and settlements away from the coast in the coming centuries…”

“Up to 13 million people in the UK face the long-term risk of coastal flooding due to the climate crisis, scientists have warned, with a ‘reasonable worst-case scenario’ suggesting the need for the large-scale movement of populations away from a dramatically reshaped coast…
Sea level has risen by about 20cm around the UK in the last century and is accelerating. A further 40cm to 60cm by 2100 is already baked in, meaning about half a million more people will be at risk of their homes being flooded, on top of the 2.5 million already in danger near the coasts. Lincolnshire and the Humber estuary are most in danger…”

“The latest Intergovernmental Panel on Climate Change assessment report highlighted the potential for more than 15 metres of global sea-level rise by 2300. In this study, [the authors] explore the implications for UK coastal flood exposure by combining national-scale flood modelling with physically-based storylines of UK sea-level rise. By 2100 all storylines show broadly similar results with at least an additional ½ million people exposed to the 1-in-200 year undefended flood extent, which represents a 25% increase compared to present day. Under the most pessimistic storyline by 2300 involving significant ice-sheet instability, an additional 13 million people could be exposed to the 1-in-200 year undefended flood event. This would imply the potential need for large-scale movement of populations and settlements away from the coast in the coming centuries. Given current global emissions pledges, exposure increases by 1.7 million people by 2300, however up to 1 million could be avoided if Paris Agreement targets for greenhouse gas emissions are met…”

Assessment of Shoreline Change in Southeast Ireland Using Geospatial Techniques
--
https://doi.org/10.3390/su18073280 <-- shared paper
--
"... KEY INSIGHTS:
• Coastlines are highly dynamic — 57% accretion vs 42% erosion
• Strong contrasts between east-facing (Irish Sea) and south-facing (Atlantic) coasts
• Identification of critical erosion hotspots (e.g., Tramore) and accretion zones in embayments
• Coastal change is driven by a combination of wave climate, sediment availability, geology, and human activity

#AskFedi
Regarding the law that air holds 7% more water per 1°C warming.Where does it come from? Does it empty the #ocean and lower #sealevel ?
(Water does evaporate from the soil and plants on land as well. But most of the warmer, water-hungry air is over oceans so most of the additional evaporation occurs there.)Where does it go, all the additional water in the air? Does it fill the whole troposphere or only up to, dunno, 5km or something?
(Water is lighter than the molecules that normally make up the air, O2 and N2. Astonishing to me. But true.)And also, I can't seem to find a CO2-equivalent global warming potential of tropospheric water vapour. Isn't it a greenhouse gas, too?
Grateful for your input!
