Knowledge Graphs
for Water Management
An intensive, in-person academic program uniting environmental engineering, sustainable water governance, and advanced semantic technologies.
Target Audience
Designed for Doctoral (PhD) and Postdoctoral researchers working at the intersection of:
- Environmental Science
- Water & Waste Infrastructure Management
- Data Science, Semantic Web & Knowledge Graphs
- Affiliated to EULiST Universities
Fusing Theory, Practice, & Interdisciplinary Projects
To address critical global issues and reporting targets on UN Sustainable Development Goal 6 (Clean Water and Sanitation) indicators, the EULiST Alliance presents an immersive, hands-on scientific camp hosted at Leibniz Universität Hannover.
In the first half of the program, participants will collaborate on sharing and integrating water-related data from diverse disciplines and repositories. In the second half, intensive group project sprints will empower participants to apply semantic models to resolve complex environmental challenges. Informal evening sessions create an open environment for discussing research, networking, and exchanging innovative ideas.
Vision for Intelligent Water Systems
Accelerating the digital transformation of water management with integrated, sustainable semantic technologies.
Topics and Learning Outcomes
Upon completion, participants will have acquired robust framework skills and practical knowledge in semantic system design:
Semantic Water Interoperability
Conceptual understanding of how Knowledge Graphs (KGs) and semantic models enhance water data integration across complex disciplines.
Real-world Resource Applications
Insight into water resource management, decision support frameworks, and regulatory sustainability policies using water metadata structures.
ORKG Infrastructure
Hands-on experience in structured scientific mapping and semantic research comparison using the Open Research Knowledge Graph (ORKG) tool and LDM.
|
Knowledge Graph Construction & SPARQL
Practical development skills in ontology design, semantic triples construction, graph architectures, and writing robust SPARQL data queries.
Personal Research Mapping
A customized, personal conceptual model applying knowledge graphs directly to your own PhD thesis or postdoctoral research work.
Interdisciplinary Project Sprints
Collaborative teamwork experience in building, resolving, and presenting team-designed semantic models for municipal water systems.

Hannover Water Systems
Klärwerk Herrenhausen
One of the primary wastewater treatment operations in Hannover and the oldest of its kind in Lower Saxony. Explores purification cycles before water is safely released back into the Leine River.
Blue-Green Infrastructure Walk
Explore Hannover's progressive urban architectural sites combining green elements (vegetated parks, green roofs) with blue infrastructure (rainwater capture basins, local stormwater retention systems) to mitigate urban heat islands and boost climatic resilience.

Questions about the program?
If you are interested in participating or have any questions about the EULiST Summer School, please reach out to our organizing committee. We look forward to welcoming you to Hannover!
How to Reach Hannover & LUH Venue
The summer school primarily takes place at the main campus of Leibniz University of Hannover (Welfenschloss) and the TIB Leibniz Information Centre.
By Air (Hannover Airport — HAJ)
Hannover Airport has direct connections to major European hubs. From the airport, take S-Bahn line S5 directly to Hannover Hauptbahnhof (central station) in approximately 17 minutes.
By Train (Hannover Hauptbahnhof)
Hannover is a major ICE high-speed rail hub. Frequent connections from Hamburg (~75 min), Berlin (~100 min), and Frankfurt (~140 min).
Local Tram to Campus
From Hannover Central Station, walk ~5 minutes to Kröpcke. Take tram Line 4 (direction Garbsen) or Line 5 (direction Stöcken) to stop "Universität" — approximately 5 minutes, 3 stops.
