Categorised Flood Hazard data for Sierra Leone. Partitioning of hazard ranges from 1 (low risk) to 4 (very high risk). The categories are defined using different return period simulations, water depth thresholds, and different flood perils. More specifically:

1 = wet in the 1 in 1000 year fluvial and flash-flood simulations.

2 = wet in the 1 in 100 year fluvial layer.

3 = wet in the 1 in 50 year fluvial layer.

4 = wet in the 1 in 20 year fluvial layer.
