Rain Gages (SWMM)
In a SWMM network, rain gages provide the source of precipitation data and can be associated with either a rainfall profile from a rainfall event or from a scalar Time Series Database (TSDB) via a TVD connector.
Rain gages can then be associated with a:
- Subcatchment - to allow a time series of rainfall inflows per unit area for the subcatchment to be included in a simulation.
- Unit Hydrograph Group - to model, for example, the extra RDII inflow during and immediately after rainfall events, caused, for example, by seepage of rainwater into defective pipes
