A settlement flood-risk decision
Compare fictional risk reduction, costs and habitat effects under a fixed budget.
Predict the effect before changing a value. Keep other values fixed, then compare the result and explain the relationship.
Explain and challenge the result
Compare with discussion guidance
Compare cost, physical exposure, preparedness and land use separately. Warnings help people act but do not lower the model’s physical exposure. Choosing all options exceeds the budget. Real design needs location-specific evidence.
