In the gwTriade project, an assessment concept for groundwater ecosystems is being developed
The development of an assessment concept for groundwater ecosystems is the focus of the new research project "gwTriade - Integrative Monitoring of Groundwater Quality". As the Institute for Socio-Economic Research (ISOE), which is involved in the project, reports, it is about the discrepancy between the high importance of groundwater and its often too low quality.
Are groundwater reservoirs in danger?
Groundwater is the most important source of our drinking water. But drought and increasing consumption are becoming a problem. Experts expect conflicts over the scarce but vital resource in the future.
With a kick-off event at the University of Tübingen and at the ASG well in Kiebingen, the collaboration of numerous experts for sustainable groundwater management began on Thursday. The research project "GW 4.0" will provide important data and tools to ensure the protection and use of this important resource even in times of climate change.
Drone-based multispectral sensors enable the detection and investigation of exchange processes between surface water and groundwater. The main tasks of WWL in the StressRes collaborative project are the monitoring of the spatio-temporal surface water-groundwater interaction using thermal drone imagery and the development of the StressRes demonstrator.
Groundwater is alive and threatened. Heat inputs pose a major challenge to biodiversity in the subsurface. In the joint project called "CHARMANT", measures for groundwater protection in cities are being jointly developed using the examples of Berlin and Karlsruhe. Interested citizens are invited to participate in the work.
The aim of the gwTriade project is to develop an integrated assessment concept for groundwater ecosystems based on ecotoxicological characterization, chemical analysis and recording of faunal diversity. Through the socio-ecological analysis, the groundwater assessment criteria developed in the project will be tested and prioritized in relation to societal objectives.
Almost 30% of the Hessisches Ried is forested. The forest plays a central role in groundwater extraction in the region and is therefore not only significantly affected by groundwater lowering, but also has an important function as the location of groundwater recharge facilities.
The aim of the proposed project is to develop and use innovative process and source indicators as well as reactive solute transport models to provide a comprehensive status description of selected groundwater bodies with regard to water quality, water quantity and ecological status.
In April, the BMBF-funded research project "gwTriade: Ecological and ecotoxicological groundwater monitoring based on an integrative triad approach" starts.
The project develops an assessment concept specifically for groundwater systems. The innovative triad approach combines the three pillars essential for holistic groundwater monitoring: ecotoxicological assessment, chemical analysis and fauna diversity.
In the joint project "WaRM", a total of ten partners from research, industry and administration will develop a water system model over the next three years under the leadership of the Fraunhofer Institute for Systems and Innovation Research ISI, using the Frankfurt/Rhine-Main metropolitan region as an example.
Groundwater is an essential part of the natural water cycle and a vital water resource for humans. In order to protect groundwater as a drinking water resource and ecosystem, the German Federal Ministry of Education and Research (BMBF) has launched the funding measure "Sustainable Groundwater Management" (LURCH).
