Managed Aquifer Recharge (MAR) is one of the options to improve aquifer conditions and raise groundwater levels. MAR is the intentional recharge of water to suitable aquifers for subsequent recovery or to achieve environmental benefits; the managed process assures adequate protection of human health and the environment. MAR can also reduce the occurrence and degree of flooding. Various methods are used to recharge aquifers, including bank infiltration, infiltration in boreholes and wells, in-channel interception and run-off harvesting. Some of these methods are more nature-based than others, e.g. infiltration via wells may be considered a less natural approach. MAR is already widely practiced across the world. The most common incentives are to increase the buffer capacity for seasonal droughts, manage saline intrusion and to create a strategic reserve for emergency situations. Benefits may extend to ecology and in specific cases to protection of wooden pilings or manage land subsidence. The suitability of the subsoil in Europe for aquifer recharge (not taking actual demand into account) was estimated using the PCRGLOB-WB model (Figure 6.5).
