Monitor river and reservoir levels

What is this?

Continuously measure water levels in rivers, reservoirs, and aquifers so that operators have an up-to-date picture of the system.

When does it happen?

Runs 24/7 as a background process. Data becomes critical during storms, droughts, and when making abstraction or release decisions.

What data is used?

Automated level sensors, rain gauges, satellite altimetry, and historical baseline data.

What decision is made?

“Are levels rising dangerously or falling below safe thresholds?”

What action follows?

Feed data into flood or drought models; trigger alerts when thresholds are breached; inform reservoir release decisions.

River levels and flows change rapidly during storms. Without continuous measurement, flood warnings come too late and water allocation decisions are based on...
