Note: Types of Stormwater Inlets from HEC12 and HEC22

Stormwater Inlets consist of four main types (http://onlinemanuals.txdot.gov/txdotmanuals/hyd/storm_drain_inlets.htm) with most common shown in Figure 1.

1. Curb opening inlets either at a sag or continuous on the street,

2. Grate Inlets either at a sag or in combination … Read the rest

How to Subdivide Subcatchments in SWMM 5

Subject: How to Subdivide Subcatchments in SWMM 5

If you want to subdivide a larger Subcatchment in SWMM 5 and get around the same peak flow then a good suggestion would be to make sure that (Figure 1):

1. The sum of the new areas equals the original Subcatchment Area … Read the rest

Subject: Modeling H2S in InfoSWMM, ICM and InfoSewer

You can model Sulfide in InfoSWMM/ICM and InfoSewer using the H2S water quality modeling option which uses BOD5 loading at nodes to estimate the S concentration in the nodes and links of the network using constant network parameters for:
