Design Method - ADS

02. Design Method

The Design Method is a traditional use of the Manning Equation and requires information regarding the roughness coefficient (n) and the pipe slope (S).  These values are obtained from design or as-built records.  The resulting pipe curve is then compared to actual flow monitoring data.

This method is demonstrated here and indicates that this sewer operates as designed, and that the flow monitor is operating correctly.  Three manual confirmations are also shown and provide a means to evaluate the accuracy of the flow monitor.

A technical paper describing the Design Method in more detail is available for download.

This technical paper was presented at the American Society of Civil Engineers Pipelines 2004 Conference.  This conference was held in San Diego, California on August 1-4, 2004.
