The Analysis Node is coordinating the efforts within DANUBIUS-RI regarding innovative, interoperable and customized sampling and analysis. The expertise and facilities bundled within the Analysis Node allow to develop and test sampling strategies and analysis methods for River-Sea Systems.
Overview
- Coordination: Technische Universität Dresden, Institute of Urban and Industrial Water Management, Institute of Hydraulic Engineering and Hydromechanics, Center for Advanced Water Research (CAWR)
- Cooperations: Terrestrial Environmental Observatories (TERENO), Modular Observation Solutions for Earth Systems (MOSES), Urban Observatory Dresden, Long-Term Ecological Research (LTER)
Challenges
- Obtain a maximum of information with limited resources: develop fit-for-purpose measurement concepts for River-Sea Systems, which efficiently and economically provide high resolution data in time and space by combining long-term monitoring, event-based measurements and laboratory experiments;
- Provide an interdisciplinary overview of the state of surface waters;
- Identify critical states and analyse trends regarding gradients of pollutants and pollutant clusters;
- Generate data for scenario-based modelling regarding the development of pollutant inputs and water quality, as well as for assessing the efficiency of measures using compound flux modelling (in cooperation with Modelling Node);
- Untangle long-term trends and event-based effects in surface waters by conducting event-based measurements as well as long-term monitoring campaigns;
- Identity and quantify emerging pollutants;
- Quantify degradation rates of pollutants by developing boat-based online sensoring methods which enable continuous measurements along rivers (lagrangian approach);
- Identify the sources of particle-associated pollutants by innovative fingerprinting methods.
Research Priorities
- develop innovative sampling, analysis and measurement methods and concepts for River-Sea Systems;
- integrate all relevant disciplines for a system-oriented assessment of the state of River-Sea Systems, such as hydrology, geomorphology, chemistry, ecology, biology, ecotoxicology and hygiene;
- assess the value of information obtained from given data sets as a function of their temporal resolution;
- assess the value of information of high frequency measurements from online measurements of indicator substances;
- develop a sampling strategy by combining stationary sampling with lagrangian sampling in order to enhance information density;
- develop a coordinated sampling strategy and customised sampling protocols for all involved disciplines.
