An illustration of stage-discharge rating curves.

Almost everything we know about our global freshwater resources is due to the humble stage-discharge rating curve. The vast majority of all flow data ever produced is the derived result of a transform from a variable that is easy to monitor continuously (stage) to a variable that is impossible to directly measure continuously (discharge). This means we are dependent on rating curves for advancements in...

Whitepaper - Stage-Discharge Rating Curves.

The rate of downloads of the paper “5 Best Practices for Building Better Stage-Discharge Rating Curves” indicates a very high latent demand for guidance on how to develop rating curves. A stage-discharge rating curve represents the relation of water level at a given point in a stream to a corresponding volumetric rate of flow. The shape of a curve can be discovered by conducting synchronized measurements of...
