Verkaik, Jarno (author), Sutanudjaja, Edwin H. (author), Oude Essink, Gualbert H.P. (author), Lin, H.X. (author), Bierkens, Marc F.P. (author)We discuss the various performance aspects of parallelizing our transient global-scale groundwater model at 30′′ resolution (30arcsec; °1/41km at the Equator) on large distributed memory parallel clusters. This model, referred to as GLOBGM, is the successor of our 5′ (5arcmin; °1/410km at the Equator) PCR-GLOBWB 2 (PCRaster Global Water...journal article 2024

Verkaik, J. (author), van Engelen, J. (author), Huizer, S. (author), Bierkens, Marc F.P. (author), Lin, H.X. (author), Oude Essink, G.H.P. (author)Fresh groundwater reserves, being of vital importance for more than a billion of people living in the coastal zone, are being threatened by saltwater intrusion due to anthropogenic activities and climate change. High resolution three-dimensional (3D), variable-density (VD), groundwater flow and salt transport (FT) numerical models are...journal article 2021

Verkaik, J. (author), Hughes, J.D. (author), van Walsum, P.E.V. (author), Oude Essink, G. H. P. (author), Lin, H.X. (author), Bierkens, M.F.P. (author)Worldwide, billions of people rely on fresh groundwater reserves for their domestic, agricultural and industrial water use. Extreme droughts and excessive groundwater pumping put pressure on water authorities in maintaining sustainable water usage. High-resolution integrated models are valuable assets in supporting them. The Netherlands...journal article 2021
