The 3rd International Summer School on Groundwater Recharge took place at HTW Dresden.

This year's Managed Aquifer Recharge International Summer School (MARISS) was attended by Master's students, PhD students, post-docs and young academics from 15 countries. The event was hybrid: in addition to the 13 participants on site in Dresden, 13 others took part online.
Due to climate change, prolonged dry periods are becoming more frequent, affecting the recharge of groundwater. In addition to demand management, groundwater recharge is an important measure to meet water demand and ensure water quality. Managed aquifer recharge (MAR), also known as groundwater recharge, water banking or artificial recharge, is the deliberate injection of water into aquifers for later recovery. This includes methods such as bank filtration, streambed weirs, infiltration ponds and injection wells. Natural water sources, appropriately treated urban rainwater or wastewater are used.
The two-week summer school included courses on various groundwater treatment methods, such as Managed Aquifer Recharge (MAR) techniques, hydraulic and hydrogeochemical aspects, siting and design of bank filtration catchments, web-based numerical modelling, removal of microorganisms and trace organics, laboratory experiments to simulate MAR processes, regulations and risk assessment. In two excursions, the participants visited the waterworks Sdier and Hosterwitz in Saxony. In addition, laboratory practicals took place at the Institute for Water Chemistry of the TU Dresden and at the HTW Dresden.
The summer school was supported by lecturers from the Institute for Groundwater Management, INOWAS and the Institute for Water Chemistry at TU Dresden, among others.
The international summer school is funded by the DAAD as part of the "HAW.international" project.
