Physically based interpolation of bathymetric data

This Easter weekend I finally found a few hours and decided to toy around with an idea I've had for ages: trying to create a physically-informed intepolation method for river bathymetries.
Local Time Stepping - Why and How?
Posted on July 11, 2022 by Nicolรกs Diego Badano
Sometimes your numerical problem is stiff, meaning you have two related timescales: one that is fast and requires a small time step to maintain stability, and the other much slower, which requires long simulation times to reach a steady state.
