Managed Aquifer Recharge, MARISS

About

Due to climate change, groundwater recharge, in addition to demand management, is an important measure to conserve, convey and safeguard groundwater systems and to protect and improve water quality. Managed aquifer recharge - MAR-, also called groundwater recharge, water banking, and artificial recharge is the targeted recharge of water in aquifers for later recovery or environmental benefit. It includes methods such as bank filtration, streambed weirs, infiltration ponds, and injection wells, and uses natural water sources and appropriately treated urban stormwater, wastewater, and other effluents to increase groundwater storage and provide supplies during drought and emergencies. MAR can play an important role as a measure to control over-abstraction and restore groundwater balance, and can also be used to maintain or improve ecosystem function and groundwater quality. The two-week MARISS International Summer School focuses on sharing and exchanging knowledge and new ideas in the field of MAR and Riverbank Filtration (RBF). MARISS is structured in a series of lectures, practical work, group projects, and technical excursions to MAR/RBF sites in Saxony and waterworks. The lectures are divided into 6 Blocks: Hydraulic Aspects, Well Design and Site Selection, Numerical Modelling, Water Quality Aspects, Monitoring and Post-treatment, Regulations, and Guidelines.
