RAPID

The Routing Application for Programmed Integration of Discharge (RAPID) is a river network routing model. Given external inflow to rivers, this model can compute the flow of water everywhere in river networks made out of many thousands of reaches.

Note: While the underlying RAPID routing methodology is highly mature and battle-tested in operational environments, this specific Python 3 codebase (RAPID2) is currently in Beta (v2.0.0b5) and under active development.

Build Instructions

If you would like to build an Operating System to run RAPID2 from scratch, we recommend Debian-based distributions and software packages for the Advanced Packaging Tool (APT) are summarized in requirements.apt to be installed with apt-get. All packages can be installed at once using:

sudo apt-get install -y --no-install-recommends \
     $(grep -v -E '(^#|^$)' requirements.apt)

Alternatively, one may install the APT packages listed in requirements.apt one by one, for example:

sudo apt-get install -y --no-install-recommends python3.11

Also make sure that python3 points to python3.11:

sudo rm -f /usr/bin/python3
sudo ln -s /usr/bin/python3.11 /usr/bin/python3

If you would like to run in a virtual environment:

python3 -m venv $HOME/venv
export PATH=$HOME/venv/bin:$PATH
