Scattergraph Principles and Practice: Part 1 Fundamentals

Thursday, November 5, 2026
|
12pm EST, 11am CST, 10am MST, 9am PST
Webinar Series Overview

The scattergraph is a powerful tool that displays depth and velocity data from a sewer flow monitor, and the resulting patterns form characteristic signatures that provide insight into conditions within a sewer.  The Scattergraph Principles and Practice webinar series is designed as an educational resource for wastewater professionals to recognize various flow conditions and understand how they impact sewer capacity and performance.  This topic will be covered in a multi-part series.

‍

Part 1 – Fundamentals

The purpose of Part 1 is to provide a basic understanding of scattergraphs, including the fundamentals on which they are built. An overview of uniform flow conditions is provided, as well as the Manning Equation that represents them. Insights that can be gained by viewing flow monitor data through the lens of the Manning Equation will also be discussed. Important things can be learned by noting when they agree and when they disagree. These fundamentals provide a basic understanding of scattergraphs and serve as building blocks to more advanced principles to follow in this webinar series.
