Curves (SWMM)

Curves are used in a SWMM network to define the functional relationship between two quantities.

The following types of curves, and the network object that uses them, are listed below:

Each curve must be given a unique name and can be assigned any number of data pairs. Curve parameters are edited in the grid window of either the Nodes Grid (Storage curve and Tidal curve), the Links Grids (Shape curve, Pump curve, Rating curve, Weir curve and Control curve), or the Subcatchment Grid (Underdrain curve), or the relevant Property Sheet.
