2D shallow water equations implemented in Julia and compiled to WASM.

The surface elevation as governed by the 2D shallow water equations. The area represents a water body of km x km with a constant depth of m. Use the mouse to change and add obstacles in the flow field.

Things to try:

• Draw some shapes
• Increase time step (when the model becomes unstable, you need to reload the page to restart the simulation)
• Change the acceleration due to gravity
• Use a negative time-step
• Note that the model can become unstable of the once the CFL conditions are not satisfied.
• A typical value of the Coriolis parameter on Earth is 0.0001 s⁻¹.
