The city of Guayaquil, located along the Guayas, is the main port of Ecuador but at the same time the planet’s fourth most vulnerable city for future flooding due to climate change, after Guangzhou, Mumbai...

Ill-posedness in modelling 2D river morphodynamics

The set of equations used in modelling river  morphodynamics needs to be (at least) wellposed  to be representative of the real natural  phenomenon. As we deal with a time dependent  process the solution needs to be wave-like to be  well-posed. In other words, the solution must  have a domain of dependence and of...
