How do I simulate an ice age?

Open this page and use the live Coastal Erosion tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive an ice age from your own measurements.

A tsunami is a shallow-water wave even in the deep ocean, travelling at √(g·h). Over 4 km of water that is roughly 700 km/h — jet speed — yet only tens of centimeters high. As it reaches shallow coast it slows and its amplitude grows as h^(−1/4) (Green's law), piling into a destructive wall.

Current speed0 km/h

Deep amplitude0.5 m

Coastal amplitude0.0 m

Governing equation

v = g h = 9.81 \cdot 4000 = 198 \frac{m}{s}

Reading this result: At 4000 m depth the pulse moves at ~713 km/h; Green law shoaling then amplifies its 0.5 m deep-water height as it nears the coast.

Power parameter

Given scattered measurements — rainfall gauges, soil samples, air-quality sensors — inverse-distance weighting estimates values everywhere in between. Each sample's influence falls off with distance raised to a power: a low power gives smooth, blended surfaces; a high power makes each sample dominate its neighborhood in sharp bull's-eyes. The workhorse of GIS mapping.

Governing equation

\overset{z}{^} (x) = \frac{\sum _{i} w _{i} z _{i}}{\sum _{i} w _{i}}, w_{i} = \frac{1}{d _{i}^{2.0}}

Reading this result: At power 2.0 nearby samples win but distant ones still contribute — a balanced surface between smooth and spiky.

About this simulation

The full Coastal Erosion tool models an ice age with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
