PCR-GLOBWB is a global hydrology and water resources model based on a grid system, developed at the Department of Physical Geography, Faculty of Geosciences, Utrecht University, the Netherlands. This model comprehensively represents the terrestrial component of the hydrological cycle. For each grid cell and daily time step, PCR-GLOBWB simulates moisture storage and water exchange between the soil, atmosphere, and underlying groundwater reservoir. The model fully integrates human water use, estimating demands for irrigation, livestock, industry, and households. These demands are then translated into actual withdrawals from groundwater and surface water sources, such as rivers, lakes, and reservoirs, considering water availability and maximum groundwater pumping capacity.
