Global, quantity only | GLOBGM, 2024, 1*1km2, 2 model layers, transient | 3 | As a first new enabled application, GLOBGM was developed, the world's first time-dependent global groundwater model with a resolution of 30 arc seconds (~1 km). The METIS graph partitioner was applied in both a straightforward and (hydrological) area-based manner. Three continental-scale groundwater models and one for all the smaller islands were derived, for a total of 278 million grid cells. Necessarily, parallel pre-processing of input data was applied. With a relatively low number of cores (up to 382 cores; with a speedup of 138 with 224 cores for Afro-Eurasia), 58 years could be computed in parallel in one night. This demonstrated that GLOBGM could also be used by modelers who do not have access to very large computer clusters. | PhD Thesis Jarno Verkaik | Quantitattive models: MODFLOW6: Verkaik, J., Sutanudjaja, E.
