Managed Aquifer Recharge as a Tool to Enhance Sustainable Groundwater Management in California: Examples From Field and Modeling Studies

摘要: Abstract A growing population and an increased demand for water resources have resulted in a global trend of groundwater depletion. Arid semi-arid climates are particularly susceptible, often relying on to support large centers or irrigated agriculture in the absence sufficient surface resources. In effort increase security resources, managed aquifer recharge (MAR) programs been developed implemented globally. MAR is approach intentionally harvesting infiltrating depleted storage. California a prime example this problem, with three cities that over million residents agricultural industry was valued at 47 billion dollars 2015. The present-day overdraft 100 km3 (since 1962) indicates clear disparity between supply within state. face anticipated effects climate change, many new projects being constructed investigated throughout California, adding those existed decades. Some common types utilized include injection wells, infiltration basins (also known as spreading basins, percolation basins), low-impact development. An emerging type actively winter flooding fields using existing irrigation infrastructure excess MAR. therefore provides excellent case study look at historical use performance MAR, ongoing challenges, novel applications, potential expansion Effective essential tool increasing security, both scale. This chapter aims provide overview most applications State neighboring regions.
