How FlowGuard Understands Flood Risk

Flood risk is not determined by rainfall alone. FlowGuard combines environmental conditions, geographic exposure, infrastructure characteristics and historical behaviour to build a clearer picture of where risk develops.

The four layers

Environmental

Rainfall, weather and surrounding conditions — the intensity, duration and timing of the water arriving on site.

Geographic

Terrain, elevation and proximity to water — where the land sits, how it drains and how close it is to the coast, lagoon and rivers.

Historical

Past flood events and recurring exposure — a record of flooding is one of the strongest signals of where it happens again.

Infrastructure

Drainage topology, condition and capacity — the channels, culverts and outfalls that carry water away, and how well they perform under load.

When Sentinel is deployed

Property-level monitoring can add direct infrastructure observations — water level, flow, silt and blockage — to the risk picture, turning a modelled estimate into a continuously measured view of a specific site.

Your site's specific terrain, drainage network and infrastructure condition.

Continuous monitoring

Sentinel

Direct, ongoing observation of the infrastructure that influences your risk.
