The eWaterCycle platform for Open Science Hydrology

Activity: Talk or presentationTalk or presentation at a conference


The eWaterCycle platform is a fully Open-Source platform built specifically to advance the state of FAIR and Open Science in Hydrological Modeling.

eWaterCycle builds on web technology, notebooks and containers to offer an integrated modeling experimentation environment for scientists. It allows scientists to run any supported hydrological model with ease, including setup and preprocessing of all data required.

eWaterCycle comes with an easy to use explorer, so the user can get started with the system in minutes. Our interactive explorer is based on the terriajs framework, and uniquely lets the user generate a hydrological model notebook based on their preferences.

The eWaterCycle platform uses Jupyter as the main interface for scientific work to ensure maximum flexibility. Common datasets such as ERA-Interim forcing data and observations for verification of model output quality are available for usage by the models.

To make the system capable of running any hydrological model we use docker containers coupled through gRPC. This allows us to support models in a multitude of languages, and provide fully reproducible model experiments.

Based on experiences during the FAIR Hydrological Modeling workshop in Leiden we have created a common pre-processing system for Hydrological modeling, based on technology from the climate sciences, in particular ESMValTool and Iris. We additionally created era5cli, an easy-to-use download tool for ERA-5 data.

During this talk we will explain how the different components make up our platform, and show how each can be used and re-used independently.
