Explore geographical models

Make a prediction, change one condition and explain what happens.

Rainfall and runoff

Change rainfall, surface cover and soil wetness; compare a simplified water budget.

A coastal sediment budget

Change incoming sediment and local retention; trace gains and losses between two beaches.

A settlement flood-risk decision

Compare fictional risk reduction, costs and habitat effects under a fixed budget.

These models use invented coefficients and simplified systems. They teach relationships and comparison, not forecasts or engineering design.
