Hydrometric Rating Application (HydRA)

Intro

A hydrometric rating curve describes the mathematical relationship between stage and discharge for a given hydrometric station. Rating curves allow to convert stage measurements to discharge measurements based on previously measured stage and discharge data pairs. The Hydrometric Rating Application (HydRA) allows users to upload any stage and discharge datasets, develop and optimize rating models as well as save and compare results from previous sessions.

The HydRA app is hosted in the BC Gov GitHub organization and is available at PLACEHOLDER. This repository contains all source code for the HydRA app and allows to run the app locally using docker.

Managing the app packages

After cloning the repository, use the poetry python package manager to install the dependencies by running poetry install from the frontend directory. To update the dependencies, run poetry update or edit the pyproject.toml file. To export the dependencies to a requirements.txt file for the docker image, run poetry export -f requirements.txt --output requirements.txt.

Running the app locally

• Create a .env file in the frontend directory of the project by copying the .env.example file and updating the values as needed. For development, the DJANGO_DEBUG variable should be set to True.
• To run the django server locally, install docker and docker-compose. Run docker compose -f ./frontend/docker-compose.dev.yml up --build to start the development server. The app will be available at http://localhost:8003. Note: the non-dev version of the app is served via nginx at http://localhost:{WEB_PORT}.
