Understanding water movement on a global scale is essential for society to predict floods, droughts and the effect of land use on water balance. However, large scale hydrology is difficult because from a hydrological point of view, every field, every street, and every part of the world is unique. We are able to understand and describe how water moves in these locations at a small scale, but due to the extreme spatial variability it is difficult to capture such processes at a global scale. We call this the curse of locality.
On top of this, existing hydrological models exist in a huge variety of programming languages, standards etc. which limits their re-usability and reproducibility.
With the eWaterCycle platform, we have developed a framework in which hydrological modellers can work together in a collaborative environment. In this environment, they can, for example, easily;
- generate input data for their models from weather reanalysis (ERA5) or climate models (CMIP) using ESMValTool,
- run models in an isolated and portable way using containers and grpc4bmi,
- compare their model results with observation data from GRDC or USGS
