MARISS 5 – The international exchange on managed aquifer recharge in Germany 2023

The two-week summer school MARISS 5 was held in Dresden, Germany from 02/07/2023 to 14/07/2023. This includes courses and lectures which are divided into 6 blocks on various groundwater recharge methods such as: site selection and design of bank filtrate catchments, numerical groundwater modeling, hydraulic and hydrogeochemical methods, removal of microorganisms and organic trace substances, regulations and risk assessment, as well as laboratory and field experiments to simulate managed aquifer recharge (MAR) processes at HTW Dresden and TU Dresden. In addition, the participants will get to know well-functioning systems during two technical excursions to the waterworks Görlitz and Dresden-Hosterwitz.

Due to climate change, prolonged periods of drought are becoming more frequent, affecting recharge of groundwater. In addition to demand management, groundwater recharge is an important measure to meet water demand and ensure water quality. MAR is the targeted 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 from treated urban rainwater or wastewater are used.

Prof. Thomas Grischeck talks about the effect of clogging in the connection between aquifer and river after a flood and affect on MAR

The Project Climate resilient management of groundwater and geohazards (CRMGG) funded for three NAWAPI young professional staff to participate in this summer school.
