# Gencade Sediment Sources and Sinks

An example of an application where a sediment source term could be applied as an input to GenCade is for a coastal engineering application where there is a dedicated fixed sediment bypassing facility that is pumping sediment across an inlet at approximately a constant rate. In this case, a bypassing term would be input as a constant rate (${\displaystyle m^{3}/}$/hr or CY/hr) over the duration of the simulation. This would function similar to a beach fill, but is input differently than a beach fill because beach fills are input as an increase in berm width.
