How to See the Highest Continuity Errors Table in the Output Report Manager of #InfoSWMM

How to See the Highest Continuity Errors Table in the Output Report Manager

In the output text report file of InfoSWMM and InfoSWMM SA there is the Highest Node Continuity Error Table. The Table shows the highest 20 Nodes for percent node continuity errors and the actual continuity error as defined by Node Outflow – Node Inflow. This table is also shown in the Output Report Manger table

The same value of Node Outflow – …

How are the St Venant Terms used in SWMM5?

 Overview

In this blog we example the St Venant terms used in SWMM5 as equations, table, graphs and units.  We use a QA/QC version of SWMM 5 that lists many more link, node, system and Subcatchment variables than the default SWMM 5 GUI and engine.  This also applies to #InfoSWMM and any software the uses the #SWMM5 engine.

How are the St Venant Terms used in SWMM5?

Figure 1 shows the terms and Figure 2  

A Visual Look at a Series of HW Force Mains in #InfoSWMM and #SWMM5

A Visual Look at a series of Hazen Williams friction loss HW Force Mains in #InfoSWMM and #SWMM5.  All of these graphs were made in the advanced graphical tools of InfoSWMM.

The figures show the progress of the water downstream along with comments on individual terms. Here is the  list of the figures

Figure 1 – All of the Force Mains (FM) use Hazen Williams (HW) friction loss (C of 100), are 3 feet in …
