eWaterCycle II

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 local 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. In the eWaterCycle II project, we are developing a framework in which hydrological modellers can work together in a collaborative environment.
