Hydrological Variability and Water Resource Management in Central Chile
Summary
Central Chile, stretching roughly between 30° and 38° S, exhibits a Mediterranean‐type climate marked by strong seasonal contrast and a pronounced interannual variability in precipitation. The region has endured a protracted megadrought since 2010, with rainfall deficits exceeding 25 %–70 % of historical norms, driving declines in snowpack, river flows, reservoir volumes and groundwater levels. Hydrological memory—influenced by the interplay of snowmelt retention, aquifer storage and catchment characteristics—modulates the propagation of meteorological drought into streamflow deficits. Agricultural and urban demand, mining abstractions and a legacy of water rights allocation have compounded water stress, leading to conflicts and challenges for equitable allocation. Management responses have included reservoir operation adjustments, improved irrigation efficiency, enhanced monitoring networks and nascent groundwater governance reforms. Nevertheless, persistent deficits and climate change projections point to increasingly limited surface and subsurface supplies, underscoring the need for integrated strategies that couple adaptive infrastructure investments with demand‐management policies to safeguard ecosystems, rural livelihoods and regional food security.

Hydrological Variability and Water Resource Management in Central Chile publication trend
The graph below shows the total number of articles in hydrological variability and water resource management in central chile across all publications each year (not limited to Nature Index journals).
Technical terms
Hydrological memory: The delayed response of streamflow to precipitation, influenced by snowpack storage and groundwater contributions.
Megadrought: A prolonged drought event lasting multiple years or decades, with rainfall deficits exceeding typical interannual variability.
Catchment: A land area drained by a common river system, where topography and geology determine runoff and storage dynamics.
Groundwater recharge: The process by which water percolates from the surface into aquifers, replenishing subsurface storage.
Precipitation‐runoff relationship: The empirical link between incoming rainfall and resulting streamflow, modulated by land cover and soil properties.
Snowmelt contribution: The portion of streamflow derived from melting snowpack, critical in snow‐dominated basins with seasonal water supply peaks.
