Conjunctive surface water and groundwater management under climate change, (Frontiers in Environmental Science)
Conjunctive water management: What is it? Why consider it? What are the challenges?, (Toccoy Dudley and Allan Fulton)
Conjunctive use is a term used to describe the planned use of both surface water and groundwater resources to maximize total water availability in a region long-term. For example, a region with surface water supplies may choose to undertake an aggressive water recharge program in wet years, with the goal of having additional groundwater in storage that can be used during dry years.
Conjunctive use is not a new concept in California. Indeed, many agencies have implemented conjunctive management programs as buffers against drought, subsidence and groundwater level decline. Conjunctive management can be large-scale, like the Semitropic Water Storage District’s 2.1 million acre feet (MAF) capacity operation or in urban environments, like the Compton Water Department’s 2,289 acre feet (AF) groundwater bank.
Conjunctive management projects have many benefits. They improve local water supply, reduce groundwater overdraft, increase flood protection, help meet environmental needs, improve groundwater quality, and counter subsidence.

Protection of Recharge Areas
Protecting natural recharge areas helps to maximize natural recharge to groundwater basins, provide flood protection, and improves water quality.
