Singapore - Catching Every Drop of Rain
The source of the map of the rivers of Singapore is the Singapore PUB
As a small island that doesn't have natural aquifers and lakes and with little land to collect rainwater, Singapore needs to maximize whatever it can harvest.
Currently, Singapore uses … Read the rest
Maximum HGL Head Class in InfoSWMM AND H2OMAP SWMM
You can find the node flood or surcharge maximum occurrence during a simulation in the Junction Summary Report table in InfoSWMM and H2OMAP SWMM (Figure 1)

Global Dry Weather Flow Reduction in InfoSWMM and H2OMAP SWMM
A cool tip to reduce the overall dry weather flow in InfoSWMM and H2OMAP SWMM without changing the mean dry weather flow is to do the following:

A divider node in the SWMM 5 Kinematic Wave solution will divide the inflow to a node for two downstream links based on three criteria:
1. Cutoff Divider,
2. Tabular Divider, and
3. Weir Divider
The rule for a Cutoff
The relationship between the upstream and downstream node invert and offset elevations, the input conduit length and the slope used in the SWMM 5 simulation are shown in Figure 1.

The objects in the General category can be applied to more than one category. For example, you can simulate pollutants either at a node or at the subcatchment level.
The objects are:
