Where is the “add link” element?
In previous versions, the “Add link” element was used to direct outflow from one node to another. The Add Link is no longer an element in V8i. To connect a catchment to the rest of the model, you would simply select the appropriate element for the “outflow node” property of the catchment. You’ll then observe a dashed line connecting the center of the catchment to the discharge point. Aside from catchments, the equivalent of the add link tool in V8i would be to use the “conduit” element, selecting “virtual” as the conduit type in the conduit properties. This would instantly carry the upstream hydrograph to the downstream node without attenuation (which is what the add link tool did in older versions). For example, Catchment > Junction > conduit (set to Virtual) > Outfall > Pond.
