Default flooding and drying in shallow water
Posts: n/a
Hello I am a Phd student on hydraulic engineering. i want to simulate the bridge hydraulic by shallow water equation considering flooding areas. in solving shallow water equation the computational domain changes and i want to know about modeling of this problem.

A simple way is slot-method /porosity method of Tao 1983, which treats the wall/beach as slots. Water can enter the slots first and then swash back and forth.

See references:

It'll be a little hard to tune the code.
