Calibration of Manning’s roughness coefficients for shallow-water flows on complex bathymetries using optimization algorithms and surrogate neural network models

•The main features of a newly developed high-performance multi-GPU solver for the shallow-water equations are presented. This solver is used to build a database of highfidelity solutions.•A surrogate model based on an ensemble of neural networks is trained on the database.•Optimization algorithms ar...
