dl4HM for bathymetry inversion

Code and data for the manuscript titled \"Bathymetry Inversion using a Deep-Learning-Based Surrogate for Shallow Water Equations Solvers\" by Xiaofeng Liu, Yalan Song, and Chaopeng Shen.

The code is a snapshot of the dl4HM repository for the purpose of satisfying the data availability requirement by journals. The latest version of d4HM can be found on GitHub: https://github.com/psu-efd/dl4HM

The bathymetry inversion cases are in \"examples/bathymetry_inversion_2D\". There are two cases. One is a simple rectangular channel and the other is a real-world case fro the Savana River, GA.
