Sediment Control Strategy

Sediment control design for a Pilbara mine site, where the risk is not the frequent rain but the rare, intense event that moves more sediment in an hour than a normal year manages.

Sediment control at this scale isn't one structure — it's a strategy across the whole site, sized and sequenced so no single point of failure undoes the rest of it.

Arid-zone catchments concentrate a year's erosion risk into a handful of storms — the strategy was built around those events, not the long dry spells in between.
