The following video shows how Itzï could be coupled with SWMM to simulate a drainage overflow. It correspond to the test 8b from the Environment Agency of the UK. A hydrograph is given 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.
Floods in Hull, UK
This video shows Itzï reproducing the 25th of June 2007 floods in the city of Hull, UK. In that case, 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.
