Posted by Ridwan Sami on August 7, 2016 at 7:55pm in SWMM5

How to describe run status for continuity error, for instance "Suface Runoff -0.25% and flow routing -0.10%. Can you describe what the menaning of the result? Why should be negative in value?

The same comments apply to both runoff and flow routing continuity.,

The same comment applies to the total continuity error

FlowTotals.pctError = 100.0 * (1.0 - totalOutflow / totalInflow);

The CE is just the Inflow - Outflow

x = 1.0 - NodeOutflow[j] / NodeInflow[j];

If the total inflow is greater than the outflow then the error will be positive

IF the total inflow is less than the outflow then the error will be negative
