Scattergraph

A hydraulic jump or other transcritical flow condition may reduce the accuracy of a flow monitor.

Surcharge conditions are common in sewer systems, especially during wet weather event.

The Stevens-Schutzbach Method is an iterative regression technique used to fit the Manning Equation to flow monitoring data.

The scattergraph depicted here reveals backwater and surcharge conditions that result in a sanitary sewer overflow (SSO) upstream from this monitoring location.

This 10-in sewer is equipped with an 8-in overflow pipe located in the downstream manhole.

The scattergraph depicted here reveals backwater and surcharge conditions that result in a sanitary sewer overflow (SSO) downstream from this monitoring location.
