# How to configure the 1D simulation window to setup an integrated river and urban simulation

When your link-lines have been created, a linked 1D river and 1D urban simulation can be set up.

A new 1D simulation should be defined and the river network details provided on the ‘Files’ tab as you would with a 1D river (only) simulation.

NoteYou have now referenced the river network and are ready to run a 1D simulation, however, to run an integrated 1D simulation you will also need to reference the urban network and link-references as shown below.

Details of run-type and timing must be defined on the ‘Times’ tab.

Your urban network and link-reference file are provided on the ‘Links’ tab.

Ensure you save your simulation to keep any changes. Your 1D integrated simulation is now ready to run.
