Two new publications in AMS Journals

Two new publications appeared in journals of the American Meteorological Society with contributions from our group: 1) In BAMS: a position paper calling for setting up a global drought forecasting infrastructure. Our group may contribute one of the global models that can calculate soil moisture drought and hydrological drought. Pozzi, W. et al., 2013: Toward global drought…

Fieldwork at Lirung Glacier Nepal

Walter Immerzeel, Steven de Jong and Marc Bierkens have conducted field work at Lirung Glacier in Langtang National Park, Nepal (4000-5000 m amsl). Marc, Walter and Steven at 5007 m altitude Using an unmanned aerial vehicle (UAV) they made overlapping photo’s of the glacier with the goal to construct a digital elevation model (4-10 cm…

Our recents efforts to model terrestrial hydrology and human impacts at (very) high resolution

The Following initiatives are underway in higher resolution modelling PCR-GLOBWB 2.0: in development.  It operates at 6 minutes globally and is coded in PCRaster-Python.  In PCR-GLOBWB 2.0 we will fully integrate the PCR-GDEM water demand calculations and then add at run-time demand-driven water withdrawal, consumptive water use and return flows as part of the global hydrological…
