GeoFlood

Flood mapping program based on high-resolution terrain analyses.

Documentation

Under construction

Usage

See the examples directory for Jupyter notebooks that demonstrate how to use pygeoflood.

Installation

pygeoflood is not yet available on PyPI. To install from GitHub, use the following command (Python 3.10 or 3.11 is required):

$ pip install git+https://github.com/passah2o/pygeoflood

We recommend installing pygeoflood into a virtual environment. Below are commands for installing pygeoflood into a conda environment¹.

$ conda create -n pygeoflood-env python=3.11
$ conda activate pygeoflood-env
(pygeoflood-env) $ pip install git+https://github.com/passah2o/pygeoflood

If you plan on running the Fill-Spill-Merge function to estimate pluvial flooding, you must also install a fork of the richdem package using the following commands:

$ git clone https://github.com/mdp0023/richdem.git richdem
$ cd richdem/wrappers/pyrichdem
$ pip install .

To obtain an editable installation for local development:

$ conda create -n pygeoflood-env python=3.11
$ conda activate pygeoflood-env
(pygeoflood-env) $ git clone https://github.com/passah2o/pygeoflood
(pygeoflood-env) $ cd geoflood
(pygeoflood-env) $ pip install -e .
