An invented estuary, 1940–2024

Tide Archive

This is not a forecast. It is a small, legible world for watching a shoreline become the record of water pressure, sediment, care, and construction. Drag through the years; tap a tile to ask what made that location change.

Water does not act alone

Rising water erodes low exposed land, but sediment accumulation can rebuild it. Vegetation slows both where it survives.

Protection moves pressure

Flood walls spare the protected tile in the short term; nearby unprotected water is pushed harder into its neighbours.

Homes change the story

Settlement seeks high stable ground, then invites a wall after enough flood years. The “safe” shore is therefore made, not found.

A deterministic fictional model, made to reveal coupled consequences rather than to simulate a real estuary. Replay always begins from the same 1940 shoreline.
