Steps to take
• Make your SFINCS model
• Create river inflow points (src)
• Create your wflow model
• Add your src points as output points in

16. Take home message
• HydroMT is a very useful tool to create models in a fast, reproducable and scalable way
• Using HydroMT we can couple SFINCS multiple models with minimum manual effort
