Managed Aquifer Recharge as a Tool to Enhance Sustainable Groundwater Management in California [PDF]

, 2018
A growing population and an increased demand for water resources have resulted in a global trend of groundwater depletion. Arid and semi-arid climates are particularly susceptible, often relying on groundwater to support large population centers or ...
