Global two-layer transient groundwater model published (and more)

We are happy to announce that Inge de Graaf published a paper about our newly-developed global two-layer transient groundwater model. This version is coupled one-way with the global hydrology and water resources model PCR-GLOBWB. A newer version also has a two-way (at time-step) coupling with PCR-GLOBWB and will be reported on shortly. You can find the paper here!

Furthermore, Yoshihide Wada (vice-director Water at IIASA and senior research associate at UU) and colleagues published a new paper in Nature Geoscience in which they show from analyses of satellite and local well data spanning the past decade that long-term changes in monsoon precipitation are driving groundwater storage variability in most parts of India either directly by changing recharge or indirectly by changing abstraction.

This is where you’ll find us at AGU 2015!

International Workshop on Hyper-resolution Global Hydrological Modelling

Toward global-scale models that are relevant at local scales!

On February 13/14 an international workshop was organized at Utrecht University, bringing together hydrologists from around the world that are involved in large-scale high- to hyper-resoluytion modelling of terrestrial hydrology. A succesfull workshop lead to the foundation of the HYperHydro network with three working groups:

  • WG1: Setting up a testbed for comparing different large-scale models at different resolutions.
  • WG2: Around computational challenges, including parallel computing and model component coupling.
  • WG3: With the goal to think about delivering the information needed to achieve hyper-resolution (< 1 km) globally: parameter sets, model concepts and forcing.

A splinter meeting will be organized at EGU 2014 in Vienna to further the network activities. You are welcome to join any of the groups by sending email to Marc Bierkens.

The workshop program and pdfs of the presentations can be found here!
