Subject: How to Make an Internal Outfall into an External Outfall when you have more than one link connected to an Outfall
Step 1: Identify the Problem “ERROR 141: Outfall J-561 has more than 1 inlet link or an outlet link.” Means you have an outfall node in the middle of your model.

Step 2: Make a new outfall.

Step 3: Make the new Outfall have the same invert as the old outfall

Step 4: Convert the older outfall to a Junction using the Pick Axe and the Convert Type tool


Step 5: Make a new Link connecting the old and the new Outfall

Step 6: Convert the new Link to an Outlet Type using the Convert Type Tool.

Step 7: Set up the parameters for the new Outlet Link


Step 8: For those outfalls that DO have more than one link you need to make a new Outfall.



You should be able to run the model now
