Itzï can be employed in a variety of usages. A few examples are presented here.
This video shows Itzï reproducing the 25th of June 2007 floods in the city of Hull, UK. The urban drainage is represented by a constant loss of 55mm/day. The domain is 87.7km², which is 3.5 millions cells at a resolution of 5m.
The following video shows how Itzï can simulate a drainage overflow. It corresponds to the test 8b from the Environment Agency of the UK. A hydrograph is set upstream the drainage network, which overflow at a manhole at the top right corner. The consecutive superficial flow is simulated at 2m resolution. No infiltration is considered.
