Are these IPCC scenarios?

No. Each level is a simple bathtub fill at that height above present sea level — chosen for comparison and teaching, not tied to a projection. The slider lets you set any level a lesson needs.

What does +10 m actually mean?

The water stands 10 metres above present sea level, and every point of land lower than that floods. Nothing about timing or probability is implied.

Can I set any water level?

Yes — the slider spans the region's full elevation range, so you can flood a mountainside valley as easily as a delta.

Which places work best?

Low-lying coasts and deltas show the most change — river mouths, barrier islands, flat waterfronts. But flooding a steep fjord at +60 m makes a memorable image too.

What elevation data is behind it?

The AWS Terrain Tiles dataset, built from SRTM, NED and other national elevation programs — roughly 30 m resolution globally, finer in many places.

Can I use it in class or in print?

Yes — course materials, editorial illustration, slide decks and similar work. Keep the credit line that ships with each export.

What is the best sea level rise map simulator?

For a free, real-terrain 3D view of a specific coastline, this tool floods the actual elevation grid with a water-level slider. For projections and timings, use NOAA or IPCC-based tools; those answer "when", this answers "what would be under water".

Can I see sea level rise for Florida or New York?

Yes — pick the state/county in the Region panel or box the coastline, then drag the water level. The same works for California, Hawaii, the UK and any coast on Earth.

Is this a flood forecast?

No. It is a static bathtub fill at a chosen height above present sea level — no tides, storm surge, subsidence or timing.

Sea level rise map simulator

One click floods the model from the region's lowest point. Watch a coastline retreat, an estuary fill in, a waterfront lose its first block — on a 3D model you can turn, tilt and fly through.

The water level

The water-level slider floods everything below the chosen level above present sea level, across the region's full elevation range — from a few metres to the top of the terrain. The water sits on the actual elevation grid, so an estuary floods through its real channel and a city loses its real riverbank, not a roughed-in shape. Switch the colour band to Absolute elevation and the same metre values mean the same thing in every region, which makes comparisons honest.

An honest bathtub, not a forecast

This is a visualisation, not a projection: no tides, no storm surge, no land subsidence, no gradual-inundation modelling. At roughly 30-metre elevation resolution it is right for teaching, journalism and illustration — not for engineering decisions. That honesty is what makes it a good classroom instrument: students see exactly which land lies below each threshold and can argue about what the model leaves out.

Sea level rise map by region

Because the tool works from real elevation data for any place, you can model sea level rise for a specific coastline rather than a fixed world map: Florida and the Gulf Coast, New York and the Hudson estuary, California bays, Hawaii, the UK and the Netherlands, or a delta in Asia. Choose the region or draw a box around the coast, switch on the water level and flood it.

This is a bathtub-style visualisation, not a forecast — it shows which land sits below a chosen level, not when the water arrives.

How it works

Pick a coastal region — a named country, state or county in Europe or the Americas, or a box drawn on any coast on Earth.
Switch to the 3D view and drag the water level.
