WebApr 12, 2024 · The mean annual groundwater discharge varies from 6 to 350 mm, and is highest in the upland slopes in the southeast of the region. Spatially, catchments with higher groundwater discharge tend to have lower inter-annual variation as indicated by the coefficient of variation. WebGroundwater recharge depends on several factors such as infiltration capacity, stochastic characteristics of rainfall, and climate factors. The spatial and temporal distribution of the rainfall mainly controls the natural groundwater recharge.
