pyscabbard 0.0.13

Suite of Hydrodynamic, topographic analysis, Landscape Evolution model and visualisation tools

Scabbard

Python package to design, use or visualise topographic analysis, landscape evolution models and hydro/morphodynamics simulations. Among other, home of GraphFlood (CPU and GPU) and CHONK. This framework is also building a GPU backend for general purpose landscape modeling.

Built on the shoulder of giants

scabbard started as a personal codebase and evolved toward a fully-fledge numerical Framework. It uses the robust and battle-tested scientific python stack (e.g. numpy, scipy, numba, ...) and geospatial python (e.g. rasterio, geopandas, libgdal, ...). It also relies on multiple domain-specific libraries to built a future-proof and community-compatible backend: libtopotoolbox and pytopotoolbox, fastscapelib, LSDTopoTool as well as my own collection of c++ and numba routines. All the GPU backends use taichi to ensure cross-platform/hardware compatibility and user-friendly code.

How to install

pip install pyscabbard

As simple as that. Thanks to github actions allowing smooth CI, you do not have to compile anything yourself.

NOTE: pytopotoolbox official installation procedure is still WIP. I provide binary wheels within this project (./wheels/pytopotoolbox ). At first import, scabbard will provide instruction (i.e. a single command line to run).

Features

• General geomorphic routines

• Graphflood: Efficient hydrodynamic modelling, tailored for large scale. CPU and GPU version.

• CHONK/trackscape/popscape: Long term Landscape Evolution Models.

Usage

Documentation is WIP and will be online soon
