Rain Barrel LID Fluxes in SWMM 5.0.021

Subject:  Rain Barrel LID Fluxes in SWMM 5.0.021

The fluxes are limited in a Rain Barrel Low Impact Development (LID) control in SWMM 5.  The fluxes only include (Figure 1 and Figure 2):

1.      Total Inflow,
2.      Surface Outflow,
3.      Drain Outflow and
4.      Final Storage

The fluxes are also listed in the LID Performance Summary Table in the output text file.
