Simulating the effects of managed aquifer recharge

The paper makes a case for achieving agro-ecological benefits by modifying water management, and particularly irrigation operations, to store surplus surface flows underground by over-irrigating farmers’ fields. While this sounds like a high-risk venture, the authors identify the theoretical conditions for it to work. They present a simulation study of water supply and demand in an agricultural region focusing on benefits of artificial recharge during wet winters when there is a surplus of surface water and fields are not cultivated. Simulation results show increases in recharge, groundwater storage, and crop production. Managed aquifer recharge (MAR) is a hot topic and tools such as this could help evaluate the cost-benefit of its implementation.
